The modification work was carried out by the Manggarai railway workshop. The compartment suite service is operated on Java by Kereta Api Indonesia (KAI).
The compartment train operates on the ''Bima'' and ''Argo Semeru'' services on the {{stnlnk|Gambir}}-{{Stnlnk|Surabaya Gubeng}} route since 10 October 2023, on ''Argo Bromo Anggrek'' on the {{stnlnk|Gambir}}-{{stnlnk|Surabaya Pasarturi}} route since 1 June 2025, and on ''Sangkuriang'' services on the {{stnlnk|Bandung}}-Ketapang route since 1 May 2026. As a result, compartment services are available only on routes connecting Jakarta Gambir with Surabaya Gubeng and Surabaya Pasar Turi, also Bandung and Ketapang, Banyuwangi stations.
The service is considered a revival of sleeper train-style travel, following the end of sleeper services on the ''Bima'' and the compartment service on ''Senja Utama Solo'' in the 1990s. However, despite being called a compartment train, it is technically classified as a corridor coach, as all cabins are connected by a central aisle.
==History== Sleeper trains were operated from the Staatsspoorwegen era through the Perumka era for overnight services, including the ''Java Nacht Express'' and later the ''Bima'' train during the PNKA and PJKA periods. Over time, these services were gradually discontinued due to financial and social issues, including high ticket prices, high maintenance costs, and reported misuse of on board facilities. Sleeper train services effectively ended in the 1990s with the withdrawal of the sleeping coach service on the ''Senja Utama Solo'' trains.
To improve passenger comfort, KAI introduced a seated premium service branded as the "Luxury Sleeper" in 2018. Despite its name, this service is often mistaken for a sleeper train coach. It is not considered a true sleeper service because the seats recline only up to 150 degrees, meaning passengers remain in a seated position. Two generations of the Luxury class coaches have been produced, all manufactured by INKA in Madiun.<ref>{{Cite web|last=Media|first=Kompas Cyber|date=2019-05-27|title=Mau Naik Kereta Kelas "Sleeper"?

As a further development aimed at offering a higher level of interior comfort and privacy, KAI later introduced a corridor compartment coach branded as Suite Class. The prototype and later production builds was assembled at the Manggarai railway workshop in 2023 using refurbished executive class coaches originally built in 2008. The service, later referred to as the compartment suite, was officially launched on 28 September 2023 to coincide with the 78th anniversary of Kereta Api Indonesia, and entered commercial operation on 10 October 2023 on the ''Bima'' and ''Argo Semeru'' services between {{stnlnk|Gambir}} and {{stnlnk|Surabaya Gubeng}}.<ref name=":0">{{Cite news |last=Laksono |first=M.Y. |date=2023-10-11 |title=KAI Resmi Luncurkan Kereta Suite Class Compartment, Nih Profilnya |url=https://www.kompas.com/properti/read/2023/10/11/113000221/kai-resmi-luncurkan-kereta-suite-class-compartment-nih-profilnya |access-date=2024-10-09 |work=Kompas.com |language=id}}</ref> Starting on 1 June 2025, compartment suite coaches are also available on the Argo Bromo Anggrek train (Gambir–{{stnlnk|Surabaya Pasarturi}}).<ref name=":1">{{Cite news |last=Shaid |first=Nur Jamal |date=2025-05-31 |title=Suite Class Compartment Hadir di KA Argo Bromo Anggrek 1 Juni 2025 |url=https://money.kompas.com/read/2025/05/31/213437226/suite-class-compartment-hadir-di-ka-argo-bromo-anggrek-mulai-1-juni-2025 |access-date=2025-06-01 |work=Kompas.com |language=Id}}</ref> In addition, compartment suite coach services are also available on the Sangkuriang train beginning with its first timetable trips in May of 2026 (on the {{stnlnk|Bandung}}–Ketapang route).
