Unlike the PRR that had an extensive infrastructure smaller roads (like the Monon) could only turn cars (and locomotives) at certain locations, so it took some planning.  As the need to turn steam diminished turning locations were eliminated.


As an interesting side note, in the intermodal era (starts in earnest about 1954) all trailers loaded and unloaded on the Monon had their noses facing north.  Thus no turning required. 


As interline piggyback cars were accepted turning once again had to be managed.

Why would you want to turn a freight car around to run the opposite direction down the line? You simply add the car. In the RARE circumstance where a car must be directionally spotted for unloading (end door must face a ramp, for example) the car would be turned using the closest turntable or wye. However, generally, there was no need to "turn" freight cars.

OK.  That brake wheel (and for all of the other cars facing you in the photograph) raises a question I have been thinking about for the last month or so.  It's not like all trains go in the same direction.  So let's say these cars are all headed west.  A freight consist that has been traveling east enters the yard.  Short of running them out on a wye, how does one turn around an incoming car to add to the westbound cars?
