Great catch! Love that SD70ACC leading! Hot-shot too, given the UPS & ToFC traffic.

Nice catch - question for you. When the operator double stacks containers, how do they secure the two together?

[@TruveIo]

I have no idea. There are holes and slots on each container but there must also be a way of securing them properly.
