Amtrak Auto Train Discussion

The hep limitations are the amp ratings of the hep cables between the locomotive and the cars, and between the cars. The amps in a electrical circuit are the same throughout the whole circuit, so every car would need to be upgraded.

I thought that all Auto Train cars had LED lighting and higher efficiency HVAC? As far as diners have not heard of any updates except LEDs.

Each 4/0 cable is rated for 200 amps. 4 cables on 4 plugs each.

I think that allowed for one extra car to be added.
