The Edge Hill cutting is rectangular in shape, bounded on three sides by the vertical walls of the cutting, and at the east by the Chatsworth Street overbridge. North of Chatsworth Street the tracks continue, still in a cutting, to join the main line north of Edge Hill Station.
At the western end three tunnels enter the west wall of the cutting. The northernmost (the 'Stephenson' tunnel) to Crown Street and the central one to Wapping date from the opening of the line while the southernmost tunnel was driven through an original storage recess in about 1846 and was further opened up when the south cutting wall was cut back by three metres after 1864 to accommodate an extra track. Of the three tunnels the Stephenson tunnel is the smallest, being 5.15 metres high to the crown of the arch, and 4.60 metres wide. At the far end, which is now blocked, there is a date stone of 1829 set into the roof. There is also a hole in the floor dropping down into the roof of the Wapping Tunnel. The tunnel is cut through solid rock and unlined with brick arching; internally it is in good condition with a large quantity of long stalactites hanging from the roof.
