Overall I feel like the Boston Sprinter route is excellent, and I must say the new sounds are excellent. The only small errors I have found so far are that the marker lights on the CTC-3 cab car seem to shut off midway through a scenario after I turned them on at the beginning. The other issue is with regards to the steps to enter the car. On low platforms they do not open (trapdoor stays down), although they do work fine on all the other cars. EDIT: It seems that they work at South Attleboro and Attleboro stations but on the Stoughton line this trapdoor is not working.
