[1] Meitetsu saw prototype railbuses developed by Fuji Heavy Industries as a solution, and planned replacing electric multiple unit trains on those sections with railbuses to remove the electrification equipments which reduces upkeep costs.

[2] Although all lines owned by Meitetsu were electrified, the company had experience in running and maintaining diesel multiple unit trains, such as KiHa 8000 series which provided service to Takayama through the Takayama Main Line owned by Japanese National Railways.

Hunting oscillation was observed during the test run, but the executives dismissed this as an unavoidable issue and approved introducing railbuses.

[6] The 10 series were constructed using feedback from prototype railbuses used in test runs on Yaotsu line.

The railbus expected usage in two-car formation on rush hours and therefore has a gangway connection on the front.

The two cars were retired following the Kurihara Den'en Railway's closure, and is now preserved in Wakayanagi.

[11][13] A single car was introduced in 1987[11] to service the Sanage side of the Mikawa line.

[5] Four additional cars were built and introduced in 1990 following the increase in de-electrified railway sections to service the Hekinan side of the Mikawa line.

Although the Myanmar Railway used the push–pull train method, the cars broke frequently as they were not designed to be used that way.

The car increased in length by a further meter, and an additional pair of doors were installed in the middle.
