Friday's VIA 15 left Halifax with CN 8817 (SD70-2M) on the head end, leading VIA 6400 and 6405. Apparently 6400's air reservoir froze, so a line was run from 8817 bypassing the two VIA locomotives to the train consist. The water in the Renaissance cars is operated by air supplied by the locomotives. The doors and steps are also operated by air.
Luc Doiron spotted reported VIA 15 by Rogersville at about 1930 with VIA 6410, 6400 and 6405 but without the CN engine, which was taken off at Moncton.
Geoff Doane has a nice shot of the train near Halifax.
Phil Ross shot 8817 beside VIA 15 in Moncton later on.

EDIT: Luc is in Montreal; he was told by someone else about VIA 15's passing!
