Rullning vs amerikanska ånglok? (Järnväg allmänt)

av Ingwar Åfeldt, Wednesday, January 02, 2008, 01:14 (6269 dagar sedan) @ HP

Att stanna med dragkraft på är för att hålla kopplen sträckta. Lokbromsen är alltså inte aktiv då. I längre amerikanska tåg är det mycket slack i centralkopplen och för att minimera slacket håller man kopplen sträckta vid inbromsning genom att låta loket/loken dra med reducera dragkraft.
