(svn r9967) -Fix (r9938): autoreplace would in certain conditions move dualheaded engines in a train (usually to the rear)
-Change: moving an engine in between the two ends of a dualheaded engine will now move the rear dualheaded engine to the front of the newly added engine (instead of moving the new engine to the rear of the rear dualheaded engine)
This can make a difference if there are wagons in the train
