Track motor car DMSu-889


The DMSu-889 (ДМСу-889) is a track motor car designed for the maintenance and repair works of the overhead contact system of an electric railway. Later it has been adapted for measuring contact lines by replacing the liftable platform with an older type current collector (pantograph).
