ELECTRIC TRACTION UNITS, THEIR CARE AND MAINTENANCE FROM THE VIEWPOINT OF THEIR UTILIZATION

The principal objectives of the maintenance in the engine sheds and repair shops for electric traction units of the West German Railroad System are explained. Research activities concerned with causes of damage and wear are reported. These activities coupled with rationalization of maintenance work recently have made it possible to reduce the number of production hours for maintenance. Since nevertheless the specific prime cost has grown because of increased labor costs, future efforts should be directed towards an intensified reduction in the number of the specific production hours.
