nice video ! I can't understand why it takes so long for JR employees to couple and uncouple trains ! for uncoupling a passenger train it shouldn't take more than a minute to do so ! just unplug the Head End Power cables and pull the pin and move the units forward, the air brake cables will disconnect themselves, there is no need to disconnect them by hand and to plug them ! this checking things 2 or 3 times seems like a waste of time and irritating.
I also noticed the crew member with the yellow hard hat wasn't wearing steel toe safety boots - just addidas running shoes - a BIG NO NO on Canadian Railways !
