PT Kereta Api Indonesia(Persero) provides extensive passenger services.
Various classes are available, from "'Argo'" class with reclining seats and plane - like facilities, executive class with air conditioner and reclining seat comparable to the better classes of other countries' railways, business coaches which recently have been equipped with air conditioner and reclining seats much like executive class, to the hard bench, but still air conditioned economy class coaches for cheaper trains.
In last couple of years, the business and economic class are in the process of being equipped with air conditioned system.
The whole process was completed in early 2013.

Sleeper trains have existed in Indonesia.
The last all-sleeper train service was Bima express train which ran from 1967 to 1984 when it was changed to mostly coach, leaving only one or two sleeping cars.
It ran in this configuration until 1995, when the sleeper cars were withdrawn and modified into seating coach.
Since 2018, sleeper trains have been re-activated for the Argo Bromo Anggrek (Jakarta to Surabaya), Taksaka (Jakarta to Yogyakarta), Argo Lawu and Argo Dwipangga (Jakarta to Solo), and Gajayana (Jakarta to Malang).

In Java, most trains connect Jakarta and the hinterland - regional (or "cross-country" services) have not been fully developed.
Between pairs of important cities such as Jakarta and Bandung, intensive hourly services are provided.

Most passenger trains in Indonesia, except commuter locals, are named.
The names varies from plainly descriptive such as Depok Ekspress (a fast service between Jakarta and Depok), through Logawa (name of a river near Purwokerto, which is served by the train), Argo Lawu (Mt. Lawu, an extinct volcano near Solo, which is served by the said express train), to more or less meaningless, though romantic, names such as Bangunkarta (abbreviation of names of cities it serves: Jombang-Madiun-Jakarta) and Matarmaja (Malang-Blitar-Madiun-Jakarta).

Railway passenger services experienced a renaissance in the 1995-1999 period, with the introduction of many new passenger express services.
With the advent of cheap airplane tickets, PT Kereta Api has experienced a downturn in the number of passengers carried, though the number has stabilized and most trains remain at more than 50% occupancy rate.
