I had the problem with this Lirr Scenario that a Train blocked the way on the Single track at Country Life Press. Adam told me I should submit a Ticket to Support. They asked me for a Video of the Problem. So I start the Scenario and arrive at the said place in Garden City. The Signal was yellow, which means it would have made me drive onto the blocked path. Just before I stopped in Garden City, I contacted the signaler out of curiosity. The yellow signal jumped to red and the buggy train started moving. In case someone has the same problem. Just try calling the signaler when you drive into Gardem City. Maybe that solves the problem
