Looking north from the U.S. Route 1 Bypass at the former S.E. Greystone interlocking. The siding on the left was the Greystone Quarry Lead. It used to extend down just pass the grade crossing and had a capacity of 94 cars. The passing siding was located to the right of the mainline track and had a capacity of 117 cars. The base for the southbound signal is visible towards the bottom of the frame on the left side of the track. The switch for the south end of the siding was located just out of view below the bottom frame of this photograph.
