I uploaded a photo of BCER boxcar X-50 to the Files section, but seems
I forgot to make a post with my question.
Though the picture was taken after 1960, the car itself is rather
older. Just yesterday I learned that it was probably acquired
secondhand from Canadian National, who had used it in special service
for a specific commodity. My question is regarding the door: I've
never seen such a door. Does anyone have any information about this
type of door?
