21. The dynamic brakes of the fourth locomotive, SP 9340, operated sporadically and were of limited use. 22. The trams had dynamic braking , where the motors were connected so they acted as a Westinghouse. 23. Before leaving the cab, the engineer applied the locomotive's dynamic brake , but failed to do so. 24. It weighs approximately 390, 000 dynamic brake . 25. It weighs approximately 277, 000 dynamic brake . 26. The only restriction is that the consist cannot be a third trailer section equipped with dynamic brakes . 27. Diesels assigned to the branch were given modified dynamic brakes to cope with the 4.5 % grades. 28. Dynamic braking alone is insufficient to stop a locomotive, as its braking effect rapidly diminishes below about.29. The locomotives also have larger fuel tanks, dynamic brakes , and operate as " road " locomotives hauling lumber. 30. The General Electric-powered cars used forced air to cool the rheostatic resistors used for acceleration and dynamic braking .
