VIA uses a split bus system for its HEP.  All cars take HEP on the right front and it exits on the rear left to next car.  Then the car also takes HEP from its front left and exits it to right rear.  The car only takes power from one of the feeds ( do  not remember which )  So 2 cars take the different sources.  When 2 or more locos on same train set up in locos so each loco provides power to say  its right feed/  Nest  loco also feeds to its right feed.  That is why  VIA can have 35 passenger cars powered on a train.  If just one loco somehow the buses are both powered from the one loco.   If one bus should fail the cars with lost power have a transfer relay to the powered bus.  On long trains OBS crew have to load shedwhen one loco fails power.

I thought CN and GO used a different HEP system than the American operators, I wonder what modifications were needed for the GP40TC to power them?

North of the border most if not all passenger operators use 575v three phase AC for HEP. 480v is not common in Canada as a utility voltage.

They were leased as GO explored the possibility of using bi level cars, which ultimately led to the development of the now ubiquitous octagonal Bombardier coaches.

Regardless, the Detroit 12v149 HEP genset in those must have sounded awesome.
