Virginia Museum of Transportation.
What is this(if I may show my lack of train knowledge)
poling pocket - indentation or cup on a rail car or locomotive in which to insert the pole. The pole was about 12 feet long made of hard wood with a steel cap on each end. With the pole inserted between the poling pockets of a locomotive and a car on an adjacent track, the locomotive could push the car. This was dangerous to the crew as the pole was difficult to place and often broke. Poling is rarely if ever used today.
Thanks I would have never got that one on my own.
Got any pictures which show roping staples?
