Since VIA predominantly uses CN's track (with some exceptions), does CN dictate which numbers VIA can use, or can VIA use any number they want? It seems that, with the exception of the Sudbury-White River train (which uses CP track exclusively), VIA only uses numbers less than 100 and in the 600's.
Yes. Their train numbers need to work within the host railroad's numbering schemes, so that everyone can communicate with everyone else.
Thankfully, VIA's trains on CN already have a pre-set prefix - P. This is then followed by 3 numerical digits, a region code and then a date code. (Anything with less than 3 digits gets prefixed with 1 or 2 zeros.) This allows them to identify every train on their system correctly, even if there are multiple trains with the same number active (such as the Canadian).
Admittedly I know less about CP's dispatching system, but seeing as how CN's can handle 4-digit train identifiers, it may be that in the future we see that become their standard. GO has already done this.
