The stock is a dual-voltage (1,500 V DC & 20 kV AC) development of the DC-only [E231 series](/source/E231_series) suburban EMU design, and can run at speeds of up to 130 km/h (81 mph) in service.[2] ## Operations - [Tōkaidō Main Line](/source/T%C5%8Dkaid%C5%8D_Main_Line) ([Shinagawa](/source/Shinagawa_Station)–[Tokyo](/source/Tokyo_Station)) - [Ueno–Tokyo Line](/source/Ueno%E2%80%93Tokyo_Line) - [Jōban Line](/source/J%C5%8Dban_Line) ([Ueno](/source/Ueno_Station)–[Haranomachi](/source/Haranomachi_Station)) - [Mito Line](/source/Mito_Line) - [Tōhoku Main Line](/source/T%C5%8Dhoku_Main_Line) ([Kuroiso](/source/Kuroiso_Station)–[Shin-Shirakawa](/source/Shin-Shirakawa_Station)) Trains are formed in 10-car (set numbers K401–K426) and 5-car (set numbers K451–K483, K551–K557) sets. 15-car formations are generally run between [Shinagawa](/source/Shinagawa_Station) and [Tsuchiura](/source/Tsuchiura_Station). 10- and 5-car sets operate singly north of Tsuchiura, and 5-car sets are used on the [Mito Line](/source/Mito_Line). 5-car cold weather sets (E531-3000 series) are used on the [Tōhoku Main Line](/source/T%C5%8Dhoku_Main_Line) between [Kuroiso](/source/Kuroiso_Station) and [Shin-Shirakawa](/source/Shin-Shirakawa_Station), to handle the change of electrification from DC to AC just north of Kuroiso. ## Formations ### 10-car sets As of 1 October 2018, 26 ten-car sets (K401–K426) are based at [Katsuta Depot](https://en.wikipedia.org/w/index.php?title=Katsuta_Depot&action=edit&redlink=1) and formed with four motored ("M") cars and six non-powered trailer ("T") cars.[3] ← Takahagi Shinagawa → Car No. 10 9 8 7 6 5 4 3 2 1 Designation Tc T M M' T' Tsd Tsd' M M' Tc' Numbering KuHa E531-0 SaHa E531-0/-2000 MoHa E531-2000 MoHa E530-2000 SaHa E530-2000 SaRo E531-0 SaRo E530-0 MoHa E531-1000 MoHa E530-0 KuHa E530-0 - Cars 3 and 8 each have one single-arm pantograph.[3] - Cars 1 and 10 have a wheelchair space.[3] - Cars 1, 5, and 10 each have a toilet ([universal design](/source/Universal_design) in cars 1 and 10).[3] - Car 8 is designated as a mildly air-conditioned car.[3] - Cars 4 and 5 are bilevel Green Cars.[3] - Car 9 in sets K412–K422 are numbered in the -2000 series and have longitudinal seating (these cars were originally cars 4 and 5 in sets K401–K406); in all other sets, they are numbered in the -0 series and have some transverse seating bays.[3] - Cars 1, 2, and 10 have some transverse seating bays.[3] ### Standard 5-car sets As of 3 March 2020, 33 five-car sets (K451–K483) are based at Katsuta Depot and formed with two motored ("M") cars and three non-powered trailer ("T") cars. ← Haranomachi Oyama, Shinagawa → Car No. 15 14 13 12 11 Designation Tc T M M' Tc' Numbering KuHa E531-1000 SaHa E531-0 MoHa E531-0 MoHa E530-1000 KuHa E530-2000 - Car 13 has one single-arm pantograph.[3] - Cars 11 and 15 have a wheelchair space.[3] - Car 11 has a [universal design](/source/Universal_design) toilet.[3] - Car 14 is designated as a mildly air-conditioned car.[3] - Cars 13, 14, and 15 have some transverse seating bays.[3] ### Cold-weather 5-car sets An E531 series train on the [Tōhoku Main Line](/source/T%C5%8Dhoku_Main_Line) in October 2017 near [Shirasaka](/source/Shirasaka_Station) As of 1 October 2018, seven five-car sets (K551–K557) are based at Katsuta Depot and formed with two motored ("M") cars and three non-powered trailer ("T") cars.[3] ← Haranomachi, Kuroiso Shin-Shirakawa, Shinagawa → Car No. 15 14 13 12 11 Designation Tc T M M' Tc' Numbering KuHa E531-4000 SaHa E531-3000 MoHa E531-3000 MoHa E530-4000 KuHa E530-5000 - Car 13 has one single-arm pantograph.[3] - Cars 11 and 15 have a wheelchair space.[3] - Car 11 has a [universal design](/source/Universal_design) toilet.[3] - Car 14 is designated as a mildly air-conditioned car.[3] - Cars 13, 14, and 15 have some transverse seating bays.[3] ### Original 10-car sets (July 2005 – March 2007) The original ten-car sets delivered without bilevel Green cars were formed as follows.[4] **Sets K401–K406** ← Takahagi Ueno → Car No. 10 9 8 7 6 5 4 3 2 1 Designation Tc T M M' T' T T M M' Tc' Numbering KuHa E531-0 SaHa E531-0 MoHa E531-2000 MoHa E530-2000 SaHa E530-2000 SaHa E531-2000 SaHa E531-2000 MoHa E531-1000 MoHa E530-0 KuHa E530-0 **Sets K407–K411** ← Takahagi Ueno → Car No. 10 9 8 7 6 5 4 3 2 1 Designation Tc T M M' T' T' T' M M' Tc' Numbering KuHa E531-0 SaHa E531-0 MoHa E531-2000 MoHa E530-2000 SaHa E530-2000 SaHa E530-2000 SaHa E530-2000 MoHa E531-1000 MoHa E530-0 KuHa E530-0 - Cars 3 and 8 each had one single-arm pantograph. - Cars 1 and 10 had a wheelchair space. - Cars 1, 5, and 10 each had a toilet ([universal design](/source/Universal_design) in cars 1 and 10). - Car 8 was designated as a mildly air-conditioned car. - Cars 1, 2, 9, and 10 had some transverse seating bays. ## Interior - An ordinary-class car with longitudinal seating in January 2022 - An ordinary-class car with a mixture of longitudinal and transverse seating in January 2022 - Priority seating in January 2022 - The lower deck of bilevel Green car SaRo E531-17 in January 2022 - The upper deck of bilevel Green car SaRo E531-17 in January 2022 - A toilet in January 2022 ## History The first E531 series trains entered service on 9 July 2005.[5] Pairs of double-deck "Green" (first class) cars were added to the ten-car sets from 6 January 2007, and all ten-car sets included Green cars by the start of the revised timetable on 18 March 2007. Two trailer cars from sets K401–K411 (cars 4 and 5) were repurposed as cars 6 and 9 in sets K412–K422. As there were 12 SaHa E531-2000 cars and 10 SaHa E530-2000 cars being repurposed (the latter type has an air compressor missing from the former type), the SaHa E531-2012 car was modified to become SaHa E530-2022. In September 2014, an additional ten-car set, K423, was delivered from the [J-TREC](/source/J-TREC) factory in Yokohama, four years after construction of the original fleet had ceased.[6] This was followed by seven new five-car sets (K469–K475) also delivered from J-TREC in Yokohama from December 2014 to March 2015.[7] Seven cold-weather E531-3000 series sets (K551–K557) were built between October 2015 and March 2017. Later in 2017, three more 10-car sets (K424–K426) and two more five-car sets (K476 and K477) were built. Then, between 2019 and 2020, six more five-car sets (K478–K483) were built. On 26 March 2021, set K417 was involved in a collision between [Tsuchiura](/source/Tsuchiura_Station) and [Kandatsu](/source/Kandatsu_Station). It collided with a passenger vehicle which caught fire and caused damage to the KuHa E531-17 car (car 10).[8] The damaged car was replaced with car 10 (KuHa E531-9) from set K409, which later received a new-build end car, also numbered KuHa E531-17.[9][10] ### Special liveries Set K451 in November 2021 To celebrate the 60th anniversary of the Katsuta Depot, set K451 entered service on 5 November 2021 in a wrapping reminiscent of the livery of the [401 series](/source/401_series) trains.[11] Set K423 also received this wrapping in March 2023. The two sets are scheduled to carry this livery until the first quarter of 2026.[12] ## References 1. **[^](#cite_ref-neko2009_1-0)** *JR全車輌ハンドブック2009* [*JR Rolling Stock Handbook 2009*].
