I haven't been keeping up on the CSXT General Bulletins, but the last time I read anything was before the line was given to MBCR. There was a General Bulletin stating that all switches in Beacon Park were spiked to allow only one way in and out of Beacon Park. From CP-4 the route is lined to Lead 3, to TV-1 down to the Engine House Lead under the Mass Pike where the lead to CP-3 & Grand Jct are. With that being said, The RBBB Circus train could still in fact access The Grand Jct. However, the question would lie....what about the flat cars for trucks and equipment? In years past, the animal cars and passenger cars be parked on The Grand Jct, while the flat cars would be parked on TV-2 in Beacon Park. Of course, now that Beacon Park is closed, who knows what will happen this year.
