Timetable run #808 Providence to Boston Back Bay South: running CTC cab, btw, but not a train issue. At a point 9.1 miles south of Boston Back Bay South, I keep encountering a red signal. PTT denied permission to proceed at restricted speed. I checked the route map and found approximately 5 northbound trains all stuck in front of me, behind red signals, with no intersecting traffic visible in any direction. No traffic moving across an interlocking, just traffic sitting ahead of me blocking the route. Is anyone else seeing this traffic lockout which makes it impossible to complete the run? Btw, newest update installed this AM, I thought some of this nonsense was resolved?
