At the February 2011 meeting of the board it was agreed to provide a new signal to replace the time-expired one on the northern approach to Castletown Station; the extant post was one of the few remaining old telegraph poles that were used to replace original versions some 30 years ago.  Whilst it would have been preferable to have located this new post on Pumphouse Curve on the other side of the station where it would be more easily viewable from the road, this post was replaced only three years ago and still has many years service.  It was also pondered whether to site the post beyond the Malew Road bridge where the final remaining slotted post was located until a few years ago, but in this location it would not be used.

The new post brings back a part of the railway's history which disappeared with the demise of the Malew Road distant signal and happily, our new post incorporates as many remaining components of this signal as possible.  It has been a long time since a slotted post signal has been used on the railway, so in addition to being a practical and useful appendage, there will be some historical context too. We are indebted to member David Booth who prepared all the working drawings based upon the old post, which after removal was stored in the yard at Port St. Mary.

A new ladder was fabricated and the job of manufacturing the post was given to the Boston Lodge Works of the world famous Ffestiniog Railway in North Wales. The post also features the unusual system whereby the lamp is sited on a metal pole parallel to the post which rotates to change the colour of the lamp depending on the position of the signal. The cost of the project was in the region of £2,000 and the new signal was erected in time for the 2012 season. It is operated manually by cable and a windlass situated on the platform end at Castletown Station.
