Which term describes a switch over which a trailing move can be made regardless of switch point position?

Explanation:
Trailable switch describes a switch that allows a trailing move to pass through regardless of how the points are set. In yard work, cars or a cut can be pushed from the rear through such a switch and end up on the desired track without needing the points reconfigured for that specific direction. This flexibility speeds marshalling and reduces the need to stop to adjust the switch. The other terms describe situations where the switch alignment matters for the train’s approach or refer to different yard infrastructure, not the ability to move through on a trailing move regardless of switch position.
