what is it?

The OR23 was a Soviet experimental locomotive built in 1949. Its cylinders were placed above the center driving axle, and had rods on both ends which transferred power to the wheels. The purpose was to balance the driving forces on the wheels, allowing the counterweights on the wheels to be smaller and reducing hammer blow on the track.
