Work will begin next week on removing the Electric Railway sign at Derby Castle.
The frame supporting the sign has become corroded and the opportunity is being taken to remove it for safety purposes ahead of winter.
The operation will involve the use of two large cranes - one situated in the Manx Electric Railway yard and another on Hague Crescent in Onchan.
The intention is to source a replacement which will be installed to coincide with the start of the 2021 railway season next spring.
The current Electric Railway sign has been in place since 1993 when the MER celebrated its centenary. Some time ago it showed ‘MER for scenery’ but was damaged by a gorse fire and was missing from its familiar position for a number of years.
