At Pacific Central, Amtrak uses VIA for Ticketing/Baggage and for the Cascades in the station. RIght next door is VIA's Vancouver Maintence Facility, where Amtrak has time to time done repairs and maintenance of the Cascades locomotives and even some Talgo work. It would be kind of hard to replace all those services in one spot in Vancouver but could be done between several contractors and facilites, which at that point, you might as well build that Scott Road station....
With that said, I asked of the Seattle engineers about the Charger showing up on the International runs and he said it would probably show up on the 510 and 517 for final evaluation so it does a quick turn that day. He said VIA could care less on what ever locomotive they put in the caged area on the platform, but their VMC team will want to look at it to see if they COULD work on it if necessary in their shops.
New Westminster to Amtrak 516, whats up with the extra 4 axles, over?
