The Isle of Man Railways:

The Ramsey Pier Railway

As well as the remaining steam railway from Douglas to Castletown; and the horsedrawn and electric railways from Douglas to Ramsey and Snaefell, the Isle of Man had a large number of smaller railways for both passenger and goods. The Ramsey Pier railway was a very short line that carried passengers along Ramsey Pier - either for its own enjoyments sake or to access the vessels that used to visit the pier.

Ramsey Pier - aka Queen's Pier - is currently derelict. Historically it is of great interest. It is also very long! In 2014 an agreement was apparently reached with a new lessee to restore the entrance initially, followed by a certain number of metres (15?) per year thereafter.
The entrance in 2009.
Another view showing the remaining decking - also 2009.
In 2015, I at last managed to visit the (free & highly recommended) Jurby Transport Museum (not to be confused with the flashy new Manx Motor Museum on the same site - which is still finding its feet) and was astounded to find that they have there the last loco used on the Ramsey Pier Railway.
The Jurby Transport Museum also has a lot on the pier and railway's history - including its various royal patronages.
