I recommend talking to someone with experience shipping reefers in Europe because small seemingly irrelevant details will make or break the design. I assume that Europe uses a lot more international reefers that don't come with their own gensets so many trains would already have power in the form of generator cars. It might be impractical to hook them up to train power without a way to synchronize all the coolers so that they don't all turn on at once and brown out the train in the middle of a climb. IIRC international reefers require three phase power with a 50 amp breaker so even 800 amps won't get you very far if they all start up at once.
