Try without the "drive to trackmark" command, as this command is actually included in the "couple at trackmark" command.

OK, I took out the drive to track mark command. Now the engine just sets at the location where the "Couple at Trackmark" was encountered. The DCC Throttle has dropped down. What can I do to get the locomotive to move to the track mark and couple to the car waiting there?
