Found a pic of where the train was parked in Nantes.

Nantes Siding

Caption reads:
MMA #1 is leaving Nantes, for Montreal, after switching the MMA Remote control caboose, and shuffling some units. The locos (along with the Remote Control caboose) for MMA #2 leaving in the evening, are in the siding.

MMA #1 and #2 are the "oil trains" to the Irving refinery in St. John, so we're talking about the same trains at the same location where #2 (the eastbound train) was parked.

And, apparently, an overnight at this location is SOP.

The freight on the #1 looks mixed rather than being a returning unit oil train.

I'm sure that parking overnight with one loco running to keep the whole train brakes on was SOP.

Too bad there was a fire in an unattended vehicle.
