Sometimes a slightly over gauge wheel set is forced by the check rail on the point to ride up on the frog and hence derail.

Therefore, Eric’s thoughts plus a NMRA guage should make the problem obvious. If as Eric mentioned with “S” bends, place a piece of straight track after the switch to add length for the lok to travel on such tight radius as would be used in a freight yard.

A lot of modern loco’s don’t like the very sharp bends of older tracks, and the bogies don’t turn far enough, especially if there is an S turn in there.
