general question when two locos are attached together how the synchronization is made. like who controls the two engines two lp and two alp are required on one loco acts as master and the other as slave. anyone can throw some light
AFAIK , It is known as Multiple Unit and commonly phrased as MUed Locos. They are connected via communication cables provided on each side of the locos. The main control unit in the leading loco controlled by LP , controls the CU of the following loco. What ever command the LP gives to the main loco, are transferred/communicated to the CU of the following loco via the connected COMM cables, i.e acceleration , brake etc. And hence they are synchronized. Hence only 1 LP and 1 ALP is required in the leading loco. We generally get to see MUed locos as they bring heavy loaded BOXN rakes here. If anyone has more to explain, please share. #technical
what about bankers and all?? I mean to say when locos are in the front and at the end of the rake????
Bankers are MUed on the back irrespective of the leading locos. BUt they are synchronized with vacuum brakes with the leading loco. Their job is to provide enough push for gradients etc.
The combined traction force come into action. i.e e.g if 2 WDG4s are MUed, their combined traction force becomes 9000hp for hauling a heavy loaded freight.
