Some really great videos and pictures, all!
FYI, for those that may not be aware, the Lionel Standard O scale 3-bay American Car & Foundry (ACF) cylindrical hoppers that they paint up in CN, Alberta, Saskatchewan, etc. are not prototypical; the cylindrical hoppers that the Canadian roads use are 88- and 100-ton 4-bay Government of Canada grain hoppers. Currently the only correct scale Canadian cylindrical hoppers in O gauge are the ones offered by MTH in their Premier line. The two cars may at a glance seem similar but there are actually quite a number of significant spotting differences between the two types of cars. They are different lengths, the bottom bay chutes and doors are completely different, and the tapered bulkhead ends are at completely different angles in addition to the frame ends for starters. Basically, both being cylindrical hoppers is where the similarities end.
Again, that just info for those that may not know or may be interested in knowing.
