Re: White material protruding from car doors.

The white material is canvas, which covered the side and end walls of the box car.
This was to keep cloth flour bags clean and protect them from snagging on anything that could rip them.
The floor was similarly covered to protect the flour bags and keep them clean.
Bagged flour weighed 100 lbs. In cloth bags it was tricky to handle or carry.
Picked up the wrong way, a bag could sometimes tear in half.
Oddly, multi-layered paper bags that replaced cloth in the 1950's was more forgiving.
