Both routes mainly operate on the U.S. Route 1 corridor between Rhode Island Avenue in Northeast Washington, D.C. and College Park, Maryland. Route P10 trips are roughly 50 minutes long and route P1X trips are roughly 45 minutes long.

== Route == thumb|left|250px|Route P1X along Baltimore Avenue Both the P10 and P1X operate out of Landover division. The P10 runs local while the P1X runs express. Route P10 operates every 30 minutes between 5:00&nbsp;AM and 12:00&nbsp;AM, while Route P1X operates every 20 minutes between 5:30&nbsp;AM and 12:00&nbsp;AM.

The former 83 and 86 also operated out of Landover division seven days a week. Both 83 and 86 originally operated out of Bladensburg Division up until June 2019, when they were shifted to make room for other routes at Bladensburg Division when Northern division closed due to structure failures.<ref>{{cite web |last1=Dodds |first1=Alex |title=WMATA plans to rebuild its 14th Street bus garage with retail, and keep its diesel fleet for now |url=https://ggwash.org/view/71278/wmatas-redeveloped-bus-garage-is-almost-ready-all-it-needs-is-the-electric-buses |website=Greater Greater Washington |access-date=9 November 2019}}</ref> During the week, Route 83 operated every 30–60 minutes between 4:35&nbsp;AM and 11:20&nbsp;PM, while Route 86 operated every 30–60 minutes between 5:00&nbsp;AM and 10:50&nbsp;PM.

Later around 1961, DC Transit Bus Route 82, was extended north of its Branchville terminus, to Hollywood, via Rhode Island Avenue, Lackawanna Street, 53rd Avenue, 52nd Place, and Rhode Island Avenue.<ref>{{Cite web |title=Vintage 1961 Washington DC Transit System Map Bus {{!}} #3867867277 |url=https://www.worthpoint.com/worthopedia/vintage-1961-washington-dc-transit-3867867277 |access-date=2024-04-18 |website=Worthpoint |language=en}}</ref> Then, around 1968,<ref>{{Cite web |title=1968 Washington DC Transit Lines System Guide Map Bus Routes Virginia Maryland {{!}} #4595483377 |url=https://www.worthpoint.com/worthopedia/1968-washington-dc-transit-lines-4595483377 |access-date=2024-04-18 |website=Worthpoint |language=en}}</ref> 82 was extended to the Seven Springs Village Apartment Complex (Hollywood) on Cherry Hill Road in College Park, Maryland, via Edgewood Road, Baltimore Avenue, and Cherry Hill Road. The line was eventually taken over by WMATA and officially became a Metrobus route on February 4, 1973, when WMATA acquired DC Transit.<ref>{{cite web |title=History |url=https://www.wmata.com/about/history.cfm |access-date=20 May 2020}}</ref>

====Route 84==== The 84 operated as part of the Maryland Streetcar Line as an extension of the 82 Streetcar Line between Branchville and Beltsville from 1902 up until 1949 when it was ultimately discontinued.<ref name="DC Transit" /> Eventually around 1973, when the WMATA Metrobus System was formed, the 84 was brought back to operate on the Maryland Line between Potomac Park and East Pines, operating parallel to Routes 82, 86, and 88 between Potomac Park and Mount Rainier, then via the former DC Transit '''East Riverdale-Cheverly Line''' Route B4's routing between Mount Rainier and East Pines, when the B4 got discontinued. The 84 eventually stopped operating as part of the Maryland Line on December 3, 1978, when it got split off into its own separate Metrobus Route named the '''Rhode Island Avenue–New Carrollton Line''', operating between Rhode Island Avenue station and New Carrollton station.

====Routes 86 and 88==== Both the 86 and 88 were created around 1973 when WMATA's Metrobus System was formed. The 86 originally operated between Potomac Park and Riverdale, mostly following 82 and 84's routing, only except diverting off Baltimore Avenue onto the intersection of Riverdale Road and then operating via Rhode Island Avenue and Queensbury Road to reach its Riverdale terminus, which is currently where Riverdale Park Town Center station is located.

The 88 follows the 82, 84, and 86's routing between Potomac Park and Mount Rainier, then operating via the former DC Transit '''East Riverdale-Cheverly Line''' Route B6 and B8's routing between Mount Rainier and Cheverly, when the B6 and B8 both got discontinued. The B6 and B8 operated on almost the same routing between Mount Rainier and Cheverly, only with the exception that B8 would divert off Landover Road to serve the Prince George's Hospital, before operating to Cheverly. The 88 followed B8's diversion off Landover Road to serve the Prince George's Hospital. Route 88 was ultimately discontinued on December 3, 1978, when Cheverly station opened and its routing between Mount Rainier and Cheverly was replaced by Route F2.

===Later History=== On March 27, 1976, Routes 82, 84, 86, and 88 were rerouted to divert off the intersection of Rhode Island Avenue NE to serve the newly opened Rhode Island Avenue station.

On February 19, 1978, 83 was created as a brand new Metrobus Route to operate parallel to 82 between Potomac Park and Hollywood, except making limited stops to provide a speedier trip during weekday rush hour/peak period times.

During this same time, the 86 was rerouted to operate between Potomac Park and College Park, to replace the former Route G6 '''Hyattsville Line''' routing between Mount Rainier and College Park when the G6 was rerouted to operate as part of the Rhode Island Avenue Line alongside Route G4 between Avondale and Metro Center station. The 86 would retain its original routing between Potomac Park and the intersection of Rhode Island Avenue & 38th Street in Brentwood, then operate via 38th Street, Hamilton Street, 40th Avenue, Oglethorpe Street, 42nd Avenue, Queensbury Road, Belcrest Road, Prince George's Plaza, East-West Highway, Queens Chapel Road, Baltimore Avenue, College Avenue, Dartmouth Avenue, Calvert Road, and Rhode Island Avenue.

On September 24, 1978, as Metrorail Service increased its frequency, Routes 82, 83, 84, 86, and 88 were truncated to only operate up to Rhode Island Avenue station, The B6 was created as a brand new Metrobus Route to operate as part of WMATA's Eckington Line between the Rhode Island Avenue station and Metro Center, to provide alternative service to the 82, 83, 84, and 86 Metrobus Routes between the Rhode Island Avenue station and Downtown Washington D.C.<ref name="1978 change">{{cite web|last=Feaver|first=Douglas|date=September 21, 1978|title=Metrobus Routes Change as Subway Service Increases|url=https://www.washingtonpost.com/archive/local/1978/09/21/metrobus-routes-change-as-subway-service-increases/e49ed523-b338-44c2-9640-9922d6eb0dfd/|website=Washington Post}}</ref> despite not operating up to Potomac Park.

The 88 was eventually discontinued on December 3, 1978 shortly after the Cheverly Station opened. The 84 was split off into its separate line named the '''Rhode Island Avenue–New Carrollton Line''', after route 84 was extended from Riverdale (East Pines), to operate to the newly opened New Carrollton station.

In August 1988, when Queens Chapel Road was closed along East-West Highway in University Park to make room for the construction of the underground Green Line tracks, the 86 was rerouted to no longer operate on Queens Chapel Road and operate along East-West Highway itself to Baltimore Avenue. The reroute eventually became permanent due to the wishes of University Park residents.

In October 1989,<ref>{{Cite web |last=Kessler |first=Rick |date=2021-07-23 |title=Cherry Hill Park: 100 Years & Five Generations Later |url=https://woodallscm.com/cherry-hill-park-100-years-five-generations-later/ |access-date=2024-04-19 |website=Woodall's Campground Magazine |language=en-US}}</ref> when the Cherry Hill Park Campground opened, routes 82 and 83 were rerouted to operate to Cherry Hill Park via the Seven Springs Apartments Complex. Also the 82 and 83's former Hollywood Loop north of Rhode Island Avenue and Edgewood Road in College Park was eliminated.

On December 11, 1993, when the Green Line extension Greenbelt opened, Route 82 was truncated to only operate on short trips between the Rhode Island Avenue station and Mount Rainier during early morning, late night, and PM rush hours only eliminating service to Cherry Hill. Route 83 would replace the 82 and operating the same routing as the 82 except it would serve the newly opened Greenbelt station in between via Greenbelt Road and Cherrywood Lane.<ref name="1993 change">{{Cite web |url=https://www.washingtonpost.com/archive/local/1993/12/09/metro-shuffling-its-bus-schedule/29c11358-4cae-44aa-91f7-d1b863257131/ |title=METRO SHUFFLING ITS BUS SCHEDULE |last=Robert E. |first=Pierre |date=December 9, 1993 |website=Washington Post}}</ref><ref>{{Cite web |url=https://metroventure.wordpress.com/2012/04/24/81-82-83-86-college-park-line/ |title=81, 82, 83, 86 – College Park Line |date=April 24, 2012 |website=Metro-Venture |access-date=April 1, 2019}}</ref>

Route 86 was also extended from its College Park terminus at the intersection of Dartmouth Avenue & Knox Road, to operate further north up to Centerpark Office Park (Calverton), to replace the segment of route R2's former routing between the intersection of Baltimore Avenue & Campus Drive (University of Maryland) and Calverton, via Baltimore Avenue, Rhode Island Avenue, Powder Mill Road, and Beltsville Drive, which was discontinued.<ref name="1993 change" /> Route 86 was also rerouted off Belcrest Road to serve the newly opened Prince George's Plaza (now {{wmata|Hyattsville Crossing}}) station.

Between 1996 and 1997, Route 81 was shifted from the North Capitol Street Line to operate as part of the Maryland Line between Rhode Island Avenue station and Cherry Hill via Greenbelt station, to simply operate as a variant of Route 83's routing, as 83 was rerouted to serve College Park–University of Maryland station via Baltimore Avenue, Paint Branch Parkway, and River Road, instead of serving Greenbelt station.

On January 13, 2001, the line was renamed as the '''College Park Line'''.<ref>{{cite web |url=http://wmata.com/metrobus/servicechange_011301_md.htm |title=Metrobus service changes effective January 13, 2001 Maryland |date=February 10, 2001 |accessdate=June 15, 2020 |archive-url=https://web.archive.org/web/20010210013516/http://wmata.com/metrobus/servicechange_011301_md.htm |archive-date=February 10, 2001 |url-status=dead }}</ref>

On May 15, 2003, the original bus bays at Prince George's Plaza Shopping Center were closed to build a new Target store. As a result, route 86 and other routes stopped directly entering and looping inside Prince George's Plaza.<ref>{{Cite web |url=http://www.gazette.net/gazette_archive/2003/200320/hyattsville/news/158762-1.html |title=Metrobus service suspended at Prince Georges Plaza |date=May 15, 2003 |website=The Gazette |access-date=April 1, 2019 |archive-url=https://web.archive.org/web/20190329001034/http://www.gazette.net/gazette_archive/2003/200320/hyattsville/news/158762-1.html |archive-date=March 29, 2019 |url-status=dead }}</ref>

On June 27, 2004, route 86 was rerouted at the request of the city of College Park to directly serve the College Park–University of Maryland station by operating along the 83's routing along Baltimore Avenue, Paint Branch Parkway, and River Road instead of operating along College Ave, Dartmouth Ave, and Calvert Road.<ref>{{cite web |title=Metrobus service route changes in Maryland begin the week of June 27 |url=https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=3051 |website=www.wmata.com |access-date=4 June 2019}}</ref><ref>{{cite web |title=Metrobus service to change on June 27, 2004 |url=http://www.wmata.com/metrobus/062704_service_changes.cfm |date=June 27, 2004 |access-date=June 15, 2020 |archive-url=https://web.archive.org/web/20040624182003/http://www.wmata.com/metrobus/062704_service_changes.cfm |archive-date=June 24, 2004 |url-status=dead }}</ref>

Due to the construction of a new curb next to the new Mosaic Apartments built right next to Prince George's Plaza station around May to June 2007, all Metrobus Routes that have previously exited Prince George's Plaza station from the northbound side had to do so by exiting Prince George's Plaza via a right turn onto East-West Highway and left onto Belcrest Road. Route 86 was in the direction of Calverton to exit Prince George's Plaza station northbound, right onto East-West Highway, and remain straight on East-West Highway to past Belcrest Road but was able to keep its entire routing in the direction of Rhode Island Avenue–Brentwood station the same as the route was still allowed to turn left from East-West Highway onto Belcrest Road, make a right turn from Belcrest Road to enter Prince George's Plaza station, and make a right turn southbound on Belcrest Road.

On August 25, 2011, WMATA added a new route to the College Park Line called "83X" as a pilot route during the summer to provide additional direct service from Cherry Hill Campground to College Park–U of MD station operating four weekdays trips only from 8:30 am to 10:00 am only from the third Monday in June through the second Friday through August.<ref>{{cite web|url=http://www.wmata.com/bus/route_changes.cfm|title=Metrobus Route Changes|website=www.wmata.com|archive-url=https://web.archive.org/web/20110623032307/http://www.wmata.com/bus/route_changes.cfm|archive-date=June 23, 2011|url-status=dead}}</ref>

During WMATA's Fiscal Year of 2015, WMATA proposed to split Route 83 and 86 into four routes. Route 83 and 86 would terminate at College Park station from Rhode Island Avenue station and be renamed Route 83S and 86S or keep their same names. The second portion was to be named Route 83N and 86N or Route R6 and R8 and will operate between College Park station and Cherry Hill (83N/R6) and Calverton (86N/R8) keeping the same routing with Route 83 and 86. All existing services would still be covered but passengers will have to transfer at College Park station to continue their trips.<ref>{{cite web |title=MARYLAND PROPOSED BUS SERVICE CHANGES FISCAL YEAR 2015 |url=https://www.wmata.com/about/public-hearings/upload/MD_Docket.pdf |access-date=9 November 2019}}</ref>

During WMATA's FY2016 budget, it was proposed for route 83 to be given Sunday service replacing route 81 and discontinuing Sunday service to Greenbelt station. Routes 83 and 86 would replace route 81 in College Park while route C2 would replace route 81 between Greenbelt station and the University of Maryland. The reason for the changes was for WMATA to make the College Park Line easier to understand for riders.<ref>{{cite web |title=81 College Park Line |url=https://www.wmata.com/about/public-hearings/upload/MD-PDF-Maps-Translations.pdf |website=www.wmata.com |access-date=23 April 2020}}</ref>

On March 27, 2016, all route 81 service was discontinued and replaced by route 83.<ref name="3/16 changes">{{cite web|url=https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=6088|title=Metrobus adds Sunday service to Greenbelt, extends Metroway as part of service changes effective March 27|website=www.wmata.com|archive-url=https://web.archive.org/web/20190329013740/https://www.wmata.com/about/news/pressreleasedetail.cfm?ReleaseID=6088|archive-date=March 29, 2019|url-status=dead}}</ref> Route 83 also added Sunday service replacing the 81 but no longer serving Greenbelt station where it was replaced by route C2.

Also, due to Metro closing at midnight during that period because of SafeTrack maintenance, select Route 83 trips were introduced to operate between Rhode Island Avenue–Brentwood and College Park–U of MD station on Friday and Saturday late nights only.<ref name="12/16 changes" />

On March 19, 2017, route 83 short trips between Rhode Island Avenue station and Mount Rainier during weekday peak hours were discontinued and replaced by route G9.<ref>{{cite web |title=March 19-20, 2017 Metrobus Service Adjustments |url=https://www.wmata.com/service/status/details/march-19-2017-metrobus-service-adjustments.cfm?alerts-widget-next-train-all=A05 |website=www.wmata.com |access-date=23 April 2020}}</ref>

Beginning on September 1, 2019, the College Park Metrobus loop was temporarily closed for construction of the Purple line at College Park station. As a result, routes 83 and 86 were temporarily rerouted to stops along River Road, and later to the west side of the station via Calvert Road in April 2020.<ref>{{cite web |title=Temporary Stop Relocation: MDOT MTA Purple Line Construction at College Park Station Bus Loop, September 1 |url=https://www.wmata.com/service/status/details/mdot-mta-purple-line-construction-college-park-sept-1.cfm |access-date=22 November 2019}}</ref><ref>{{cite web |title=MDOT MTA Purple Line Construction Project {{!}} WMATA |url=https://www.wmata.com/service/status/details/college-park-purple-line.cfm |website=www.wmata.com |access-date=18 May 2020}}</ref>

In May 2020, WMATA announced that route 83X would not operate during the 2020 summer season due to the ongoing COVID-19 pandemic and Metro's reduced service since March 16, 2020. Alternative service would be provided by routes 83 and 86.<ref>{{cite web |title=Route Cancelled: The 83X Will Not Be in Service This Summer {{!}} WMATA |url=https://www.wmata.com/service/status/details/route-cancelled-83x-summer.cfm |website=www.wmata.com |access-date=27 May 2020}}</ref> The 83X suspended was lasted into 2021, and was never returned to service by the September 5, 2021 changes.

On September 26, 2020, WMATA proposed to reduce the frequency of buses to every 60 minutes on both routes 83 and 86 and eliminate all route 86 Sunday service due to low federal funding. Route 86 has not operated on Sundays since March 15, 2020 due to Metro's response to the COVID-19 pandemic.<ref>{{cite web |title=Proposed Service Adjustments by Jurisdiction |url=https://www.wmata.com/initiatives/budget/upload/proposed-service-adjustments-by-jurisdiction.pdf?fbclid=IwAR2yAnFIhNZRyVMm07dbgmkZO9jhR5aZWUeuhd1dWN2Y3RrXVvi0LHrqTLY |access-date=27 September 2020}}</ref> Later in February 2021, due to low federal funds, WMATA proposed to extend route 83 to Greenbelt station to replace route C2 and eliminate all 86 service if WMATA does not get federal funding.<ref>{{cite web |title=FY22 Proposed Metrobus Service Changes Maryland |url=https://www.wmata.com/initiatives/budget/upload/Proposed-MD-Bus-Changes.pdf |access-date=6 April 2021}}</ref>

===Better Bus Redesign=== In 2022, WMATA launched its Better Bus Redesign project, which aimed to redesign the entire Metrobus Network and is the first full redesign of the agency's bus network in its history.

In April 2023, WMATA launched its Draft Visionary Network. As part of the drafts, WMATA proposed to have Routes 83 and 86 terminate at both Greenbelt station and College Park–University of Maryland station, respectively, which are named Routes MD249 and MD250 in the draft. Route 83 service between College Park and Cherry Hill was renamed to Route M349 and was extended to Goddard Corporate Park via Paint Branch Parkway and Good Luck Road. Route 86 service between Hyattsville Crossing and Calverton was also renamed to Route M248, which was extended to White Oak Shopping Center and skipped College Park station in the process. Route 86 service between 38th Street and Hyattsville Crossing was replaced by Routes DC114 and MD344.<ref>{{cite web |title=Draft Visionary Maryland Routes |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/DraftVisionaryRouteProfiles041723-EN_MD.pdf |access-date=29 July 2025}}</ref>

During WMATA's Revised Draft Visionary Network, WMATA renamed the MD249 and MD250 into Routes P1X (MD249) and P10 (MD250). Route P1X kept its routing from the Draft Visionary Network, operating between Rhode Island Avenue station and Greenbelt station, but Route P10 was rerouted inside Hyattsville to serve Jefferson Street, 42nd Avenue, Queensbury Road, Hyattsville Crossing station, and East-West Highway before resuming its routing along Baltimore Avenue, following a similar routing to Route 86. Route MD248 was also renamed to Route P11 and kept the 86 routing between Hyattsville Crossing and Calverton, but was also extended to Greencastle Park & Ride via Cherry Hill Road, Old Columbia Pike, Briggs Chaney Road, and Briggs Chaney Park & Ride.<ref>{{cite web |title=Revised Visionary Network Route Summary |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/BBNR_Phase-2-Comment-Response-Summary-2.pdf |access-date=29 July 2025}}</ref> All changes were then proposed during WMATA's 2025 Proposed Network.<ref>{{cite web |title=Proposed 2025 Network Maryland Routes |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/EN-MD-Route-Profiles-05-07-24.pdf |access-date=29 July 2025}}</ref> The MD349 was also retained by WMATA as Route P46, but was cutback to College Park station and was rerouted to New Carrollton station from Doctors Community Hospital and was ultimately dropped from the 2025 Proposed Network.<ref>{{cite web |title=Revised Visionary Network Route Summary |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/EN-Visionary-Route-Frequency-Table-05-10-24.pdf}}</ref>

Throughout the proposals, Route P1X was rerouted from Greenbelt station to IKEA Way in College Park, with service between Greenbelt station and Greenbelt Road & Baltimore Avenue operated by Route P32 between Greenbelt and Fort Totten station. Route P11 was also removed from the proposals in favor of Route M44, which operated between North Bethesda station and Hyattsville Crossing station via the former C8 routing between North Bethesda and White Oak, and the proposed P11 routing between White Oak and Hyattsville Crossing.<ref>{{cite web |title=Maryland Better Bus Routes |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/Resource_2025-Route-Profiles_Maryland.pdf}}</ref>

On November 21, 2024, WMATA approved its Better Bus Redesign Network, with service on the Baltimore Avenue Line being simplified.<ref>{{cite web |title=Metro Board of Directors approves Better Bus Network Redesign, new bus routes to start next summer |url=https://www.wmata.com/about/news/Metro-Board-of-Directors-approves-Better-Bus-Network-Redesign-new-bus-routes-to-start-next-summer.cfm |website=WMATA |access-date=23 January 2025 |language=en}}</ref>

Beginning on June 29, 2025, Route 83 was renamed to Route P1X and was rerouted to serve IKEA Way in College Park, discontinuing service to both College Park station and Cherry Hill. Service was also rerouted to remain along Baltimore Avenue, discontinuing service along Greenbelt Road, Rhode Island Avenue, Edgewood Road, and Cherry Hill Road. Service between College Park station and Cherry Hill was replaced by Route M42, which operates along the former 83 routing between College Park and Cherry Hill, and extended to North Bethesda station via the former C8 routing. Route 86 was renamed to Route P10 and was rerouted along Jefferson Street and 42nd Avenue in Hyattsville, eliminating service on 38th Street, Hamilton Street, 40th Avenue, and Oglethorpe Street. The route was also cutback to terminate at College Park–University of Maryland station, with service between College Park station and Calverton replaced by Route M44 which operates between Hyattsville Crossing and North Bethesda stations, following the former 86 routing between Hyattsville Crossing and Calverton, skipping College Park station in the process. Service along 38th Street was replaced by Route C41, while service along both Hamilton Street and 40th Avenue had no replacement service.<ref>{{cite web |title=Maryland Route Profiles |url=https://www.wmata.com/initiatives/plans/Better-Bus/upload/MD_Routes_042525.pdf |access-date=29 July 2025}}</ref>
