I have been trying to accomplish my acheivement section in TS12. In the Norfolk & Western Section, I had accomplished this section. But on the west-bound freight section, it is instructed to be cleared from the yard once you connect to the freight cars. Any ideas were you need to be positioned in order to proceed from the yard. I tried numerous times, but I had never received a clearance to leave the yard even after an hour when the east-bound train is at the wye. Any suggestions?
