With downsizing and outsorcing, now when your parcel gets loaded in the van, the van is loaded on a flat and shipped by rail to wherever you live. Yeah right, 13 brand new Daimler vans, most likely from Dartmouth, NS are heading West to serve you. Such loads are somewhat common on CN IMS trains, not sure why this one is on a manifest. Please note the van variety: various window configurations, extended versions and downright minibusses.
About the bottom photo, as the train was moving I managed to get two sideshot rosters, of the 1st and 5th flat respectively. I thought it'll be a good idea to digitally stich them as the middle cars, but the results are downright bad. For starters looking at the main photo you clearly see that the shorter TTX flats are at the side, plus the grass and clouds overlap for obvious reason - the two photos were taken seconds apart on the same set of track, same zoom, same position...
