Several old 'car pushers' are still around too (I recall using one to spot a
hopper @ a Sanding facility) - could inch cars using that 6-7' pole with small
wheel on end pushing underneath a car wheel. Gerald

Glen, An old carman showed me how to move a car by myself at least a
ew feet. By grabbing hold of the flange right where the wheel is
itting on the rail and pulling straight upward the car will start to
ove. Works easier on empties of course. They also showed us how to
et a jam (two knuckles closed together and not coupled)opened so the
rack can be coupled up. Many of these old Indian tricks saved a
rainman a lot of steps and time. Archie

This isn't related to a car rolling on its own, but I was on a B&B
gang that had to move a material gon a few fit on a spur track, and
5 of us were able to move it (by pushing and using pinch bars) on
level track with the brakes released. It was then that I realized
it doesn't take much effort to get a freight car to roll.

It seems to me that everyone on this list is here because we admire,
love, and are generally curious about all the aspects of
railroading. So, this question, though off-topic, might be of
general interest to all, and of specific interest to those who know
physics.
Railroading began and continues to be a popular and effective way of
moving freight because a rolling steel wheel on a steel rail is very
efficient. I have seen reports that an 8- wheel freight car rests on
less than 2 square inches. And, it is steel on steel - little
friction. Moreover, I am sure all of us have witnessed the very long
distances that a very slow moving freight car can roll on its own.
It is phenomenal. So
here's a theoretical question:
If an ordinary, empty, boxcar resting on 2 roller-bearing 4-wheel
trucks was given a 50 mile an hour push on a perfectly level,
perfectly straight railroad track on a windless day, how far would
it go before stopping on its own?
It also would be interesting to hear some of your stories known from
personal experience regarding long distances rolled by railroad cars
moving on their own. Another phenomenon worthy of comment would be
just how silently they roll. I'm sure many have stories about that,
too.
