For the second time in this series we concentrate on the trailers performing a valuable service to MER.

The oldest of the operational trailers on the Manx Electric Railway is 51. Built in 1893 for the opening of the line this trailer has carried no fewer than four different numbers over the last 125 years although for the majority of time has been known as 51. It is caught on camera here at Derby Castle with 1 for company on 7th September.
