The Dudley Canal Line No 1 runs from Tipton Junction with Old Main Line of the Birmingham Canal to Delph Bottom Lock where it joins the Stourbridge Canal. The canal is 4.6 miles (7.4 km) long and has 12 locks. 1.8 miles (2.9 km) of that length are covered by the Dudley Tunnel.
The Dudley Canal Line No 2 runs from Park Head Junction with the Dudley Canal Line No 1 to Hawne Basin, where it currently terminates. The canal is 5.5 miles (8.9 km) long and has no locks.
