This standard plan was referred to as the 24' x 64' plan. It contained living quarters for an agent/operator. It came with two floor plan configurations, one with a single waiting room, one with segregated white and colored waiting rooms.
At first glance, this looks quite a bit like the old depot at Bragg City, MO, MP 222.1, Leachville Subdivision, Caruthersville Branch. I'll have to confirm, but meanwhile I can't wait to start scratch building. Thanks for posting, Karl. Best Regards,
