Stops to keep cars from rolling?

[Boyd]

What do you use on sidings to keep cars from rolling out of position?

Bumpers on the ends. I don't need anything on the switch side because my track is level. If your track isn't level then you could wedge a piece of scotch tape on the track under the trailing truck of the first car.

If you mean like on display, I've used the real small binder clips, cliped to the rail then remove the "wings" leaving the clip behind

Slide the Gargraves tie to the end of the track, Krazy Glue 2 stained  vertical pieces of hobby shop  square stock to the tie. Want to get complicated? Purchase a blinking diode and build your own woodstyle end of track barrier.

I've used a strip of clear styrene just long enough to reach above the axels and glued to a track tie.
