This greatly reduces the time lost by the first train to arrive at the crossing loop for the opposing train to go by. This system is referred to as a dynamic loop. For example, the Windermere branch line will be getting one to permit a 2tph service pattern.

Some railways fit catch points at the ends of crossing loops so that if a train overruns the loop, it is derailed rather than collide with an opposing train.
