Title: TECHNICAL PROGRAM IN LOCOMOTIVE EQUIPMENT. NINTH FIVE-YEAR PLAN: SOME ASSESSMENTS AND PROSPECTS IN THE DEVELOPMENT OF RAILWAY TRACTIVE STOCK
Abstract: Within the context of the plan for renewing railway equipment, tests are currently being carried out on models of electric and diesel locomotives, for both freight and passenger traffic and also on new types of motive and trailer stock. The writer briefly examines the technical characteristics of the new locomotives and their constructional features. He describes the modernization work on old rolling stock, and the improvement of production line rolling stock. Some of the major improvements obtained in freight locomotives are as follows: increase in axle load to 27-30 t for a.c. electric locomotives, and to 25-27 t for d.c. electric locomotives; increase in the axle rating to 700-800 kW for d.c. electric locomotive, to 1,000 kW for a.c. electric locomotives with 27-tonne axle loads, and to 1,300-1,500 kW for a.c. electric locomotives with 30-tonne axle loads. For diesel locomotives, it is planned to increase the rating to 1,000 h.p; fitting of regenerative braking on a.c. locomotives; use of non-commutator motors and multiple-unit running. With regard to the future of a.c. electric freight locomotives, it is planned to construct an 8-axle locomotive with a rating of 10,000 to 12,000 kW (1,300-1,500 kW per axle). For high-speed, d.c. lines, technical specifications have been drawn up for the supply of a CS200 model double electric passenger locomotive, with 8-axles and an output of 8,400 kW, designed for a maximum speed of 220 km/h.
