After introducing the 214M Partner diesel railcars to the Polish market in 2001,[5] Pesa decided to produce similar vehicles for broad-gauge railways.

The Belarusian vehicles were produced in collaboration with Belkommunmash in Minsk, which was responsible for tasks such as interior outfitting.

Following the experience with the 620M, railways in Ukraine and Lithuania decided to also order a more spacious, two-car version of these vehicles – the Pesa 630M.

Ukrainian Railways initially planned to order diesel railcars from the Czech company Vagonka Studénka.

[1] Originally, the order consisted of four diesel railcars intended for use on lightly trafficked routes.

[15] This vehicle, painted in colors reflecting the flag of the Autonomous Republic of Crimea,[4] was officially launched on October 26 at the Simferopol railway station.

[19] In 2008, Lithuanian Railways placed an order for 620M railbuses to service local lines with low traffic volumes.

[20] In 2009, the four delivered Pesa units also serviced routes from Vilnius to Šeštokai, Radviliškis to Mažeikiai, and Šiauliai to Rokiškis.

Besides the previously mentioned routes, the 620M units also operate connections from Vilnius to Stasylos [pl], Kalveliai Eldership, Ignalina, and Marcinkonys, from Kaunas to Marijampolė, Kybartai, Šeštokai, and Trakai, and from Radviliškis to Šiauliai.

[28] In 2013, Pesa signed another contract for the delivery of additional rail vehicles to Belarus, specifically three units of the 730M type.
