Yes, where the box beam lowers is generally some kind of special track that requires extra space for equipment like brakes, kicker wheels, etc. In this case, that would be the trim/block brake before the turn to the transfer blocks. I believe there were 4 possible blocks prior to entering the station, which may seem like overkill, but probably helps a lot with dispatch timing while keeping things safe. There would be the tunnel, transfer track, the brake section next to the maintenance building, and then that first brake section at the end. I may be wrong and it may only be 3, and either the one before the turn isn't a block, or the entire length of the transfer table and shed may be one, but I seem to remember several rides where the train came to a complete (very brief, but complete) stop instead of just trimming before continuing the turn to the transfer area.
