Railbuses designed for use specifically on little-used railway lines were commonly employed in countries such as Germany, Italy, France, the United Kingdom, and Sweden.
The NZR RM class 88-seaters were a class of railcar used in New Zealand. New Zealand Government Railways (NZR) classified them as RM (Rail Motor), the notation used for all railcars, numbering the 35 sets from RM100 to RM134. They were the most numerous railcars in NZR service. Their purchase and introduction saw the demise of steam-hauled provincial passenger trains and mixed trains, and was part of a deliberate effort to modernise NZR passenger services at a time of increasing competition from private motor vehicles. Being diesel powered and lighter the railcars were less expensive to operate and able to maintain quicker timetables, although became plagued with mechanical and electrical problems, with a number of the class eventually being turned into depowered locomotive-hauled carriages and reclassified as the AC class "Grassgrubs".

The Capital Express was one of the six daily intercity trains operating between Istanbul and Ankara on the Istanbul-Ankara railway before the Yüksek Hızlı Tren high-speed train service replaced all intercity trains on the line.

The train would complete its journey in just over four hours and in the Eskişehir Province, trains would reach conventional speeds of 150 km/h (93 mph), which still hold the record for fastest conventional train service in Turkey. When the high-speed rail service was opened between Ankara and Eskişehir on 13 March 2009, the Capital Express, along with the other five intercity trains, were cut back between Istanbul and Eskişehir.

TCDD UIC-X coaches were a type of passenger railcar that the Turkish State Railways operated on most express and regional trains from the 1970s to the early 2000s.

Before the TVS2000 became the new standard of the railway, these coaches were the most popular railcar in the country. Beginning in the 2000s, they have been slowly phased out, with a large majority of them being retired or refurbished into modernized railcars, similar to the TVS2000s.
