However, existing children's railways continued to be used, and new tracks and locomotives were built even after the break-down of the Soviet Union.

Most of these railways operate diesel engines, but some of them occasionally fire up old steam locomotives.

The Kambarka Engineering Works began in 2008 with the development of a modern diesel locomotive specifically for use on children's railways.

Using experience with older models, the following changes were implemented: the locomotives have two equal cabs with an ergonomically designed dashboard and HVAC (heating, ventilation, air condition), a JaMZ 6563.10 (ЯМЗ 6563.10) diesel engine with 169 kW (227 hp) at 1,900 rpm, and a four gear Voith Type D864.5 hydraulic gearbox.

Most of the locomotives were painted in a variation to a common RŽD livery in the Russian national colours, except TU10-002 of Nowomoskowsk.
