The Liverpool Overhead Railway

I found this cool strip map of the Liverpool Overhead Railway, the first elevated electric railway in the world. It opened in 1893 and was dismantled in 1957 because the company could not afford to make the necessary repairs. This map is dated "c1938".

According to the Flickr page, the map was folded into three and placed in a guide booklet. Here is a detail of the downtown area.

The railway served the docks but also billed itself as a "scenic tour" as you could see into the docks from above.

The map is adorned by flags of the various shipping lines and some facts about the railway and dock system. There were 70 docks served by the railway. As a nice touch there's also an arrow at the northern end pointing you to "Sunny Southport"
