The Canadian National Railway CNR, operates a large truck fleet. Some trucks haul inter modal containers for deliveries from railroad hubs. Other trucks are used in the maintenance of the company's infrastructure. They also have an assortment of specialist vehicles that are not seem very often. One of those unique trucks paid a visit to Halifax recently as part of the Port of Halifax's "One Port Day" when many of the port's users had a sort of open house.
CN's safety promotion activity involves a miniature "replica" locomotive called Little Obie, that does not run on rails, but hauls several open "cars" for passengers. The little train criss crosses the country to promote rail safety, and travels in its own special trailer, hauled by a custom Freightliner truck.
The truck is fitted with "fifth wheel" equipment to haul the trailer, and was upfitted out by Auto Truck Corp a specialty vehicle builder. It is actually operated by CN Police, the company's private police force, that has rail safety as part of its mandate.

Trains travel on wheels, and the friction from steel wheel to steel rail leads to wear. Also train wheels develop flat spots from emergency braking. The banging that results from the latter can be damaging to rails and to the rail cars themselves. Periodically wheels must be replaced and the worn wheels sent off for repair. New or reconditioned wheels ( in pairs, and on their axles and complete with end bearings) are then sent out on flat bed containers to rail rail yards where they are stockpiled for installation when needed. Worn wheel sets are picked up periodically and sent off repair.
I recently spotted one of Atlantic Tiltload's Western Stars with a Landoll tilt deck trailer, complete with special steel frame on the deck, leaving the intermodal terminal with a load of wheels. (By the look of the bearings, the rusty wheels seem to be new - the shiny ones show signs of wear.)
The multi-purpose 'Star is equipped with its own Palfinger knuckle boom crane.
