East of the station, the M train (and the E train during late nights) crosses from the express track to the local track, after which the tunnel widens to include a lay-up track that forms from the two express tracks and then merges with the northbound express track. This track is used to relay the New York Transit Museum's holiday trains in November and December. The tunnel then widens again to allow the IND 63rd Street Line ramps to rise and lead trains to merge with either the local or express tracks.
