The following is taken from the Disused Stations in the UK website

The most famous closed railway in Liverpool is of course the Liverpool Overhead Railway.

 
 

Dingle Station, Toxteth Dock, Herculaneum Dock, Brunswick Dock, Wapping Dock and Canning being perhaps the most local. Other Liverpool disused stations also feature on the website

A site dedicated to Dennis John Norton a Birmingham photographer contains more photographs and insights into the railway.
