After several years of operating Pesa-built diesel railcars of types 610M and 620M, Ukrainian Railways decided to purchase two-car units from the same manufacturer.

[1]The 630M cars are directly derived from the Pesa 620M diesel railcars, with modifications such as replacing one driver’s cabin with additional passenger space and adding an inter-car passageway.

[7] A notable difference from the Ukrainian Railways models is the updated front design, along with enhanced accessibility features – two lifts and a specially equipped toilet.

[2] The units ordered by Lithuanian Railways also include a higher maximum speed and a distinct front design compared to previous models.

Both vehicles were intended for services connecting Hrechany [pl] with Vinnytsia and Shepetivka in the South-Western Railway Directorate.

By the end of October 2012, the Kazakh unit was operating three times a week, completing 51 pairs of trips and covering a total distance of 22,184 kilometers.
