I am kind of surprised no one has made a "delayed" circuit for sale. Something where you can "dial up" a time (say up to a minute) before the switch will receive power again.
Another approach would be a timed circuit where you "dial up" a time (say up to 5 seconds) of how long to apply power for a given trigger. So train hits derailing trigger and circuit fires for the short time it takes to operate the switch-machine. Then it turns off and sits idle until the trigger goes away (i.e., the entire consist passes thru). When the trigger goes away the circuit re-arms ready for the next train...which could be 1 second later.
