I am playing the CRR timetables with the CRR SD-40. Extra 3014 South - Southbound Coal Approximately 10 miles from Dante I get a red signal. When I stop I see another train coming the other way but stopped. About 10 minutes after I stop at the signal the engines uncouple from the cars and come to the crossover in front of my signal. They switch tracks and reverse back to pick up a string of hoppers in the siding. The engines then return to the cross over but instead of reversing down to the waiting original consist they just sit there as if waiting for a signal to proceed. I left it for 15 minutes but still no movement Has anyone else encountered this and is there any solution to this seeming bug?
