11. As a result . the rebuilt Class 18E locomotives were equipped with rheostatic braking instead of regenerative braking. 12. Locomotive electric brake ratings are ~ in regenerative mode and ~ in rheostatic ( resistor-only ) mode. 13. All units also feature a separately excited rheostatic / regenerative brake, which is coupled to the air brake. 14. In DC mode, rheostatic braking by self-excitation of traction motors available until 17 km / h. 15. The General Electric-powered cars used forced air to cool the rheostatic resistors used for acceleration and dynamic braking. 16. This arrangement gives improved control of traction current over conventional rheostatic systems and gives fine control when starting a train. 17. The rheostatic braking fades as the speed drops below, and so slow speed braking was always by friction brake. 18. In addition to the usual slipper brake, hand brake and rheostatic brake, they had a magnetic runback brake. 19. The trains have air-operated ( pneumatic ) and rheostatic brakes, with an emergency stopping distance of 350m at. 20. Subsequently, many of the older cars in this class were retrofitted with airbrakes and had their rheostatic braking systems removed.
