Hey has anyone had success getting intermodal services to get moving forward? I went through the hill start training session (with success) and I've tried to use a similar technique with these services. But I get the throttle up to 4 and the train stretches out and stops then I try throttling up to 5 and the wheels just spin like nuts. then I reset the throttle to 0 and the train contracts again. It's like the end of the train is tied down or the brakes on the cars aren't releasing. All the services I've tried start on level ground.
