Not sure what you mean by 'hatch bracket'? But if you mean the hinges, then it can be either direction. They made cars both ways. Not sure why but there are plenty of prototypes showing both.

AFAIK in the most cases the hatches opened to the end of the car. To cool the cars down before loading, the hatches were opened half and cold air was blowed through the car. Sometimes the hatches were left open during the transport: http://images.halinet.on.ca/8193/data?n=1
The cars I'm working on are 4 hatch 36' cars that MDC produced. I got them with the thought of putting a small butcher shop outside city limits and having them transport fresh meat to a canery, where something like "Pops Beefstew " might be served with some light street running.
I'm also going to need a can making factory.
Which all the factory's will be served by my traction line, and all the employee will ride the trolleys to work because cars are just yucky....
