a) The locomotive is operated with a train of 300 t wagons behind it, on a route section with an application slope of 10%. How long can the speed of this train be increased from 66 km/h to 150 km/h on the exit side? b) Calculate the load that the locomotive can pull on this route (in the exit direction) at a regime speed of 150 km. • The specific resistance will be calculated by the relation a w 0=2+- 40000 kg/t
