 The "H" class of wagon were part of the goods fleet of the Isle of Man Railway and consisted of a four-wheel two-plank construction; these had all been scrapped by the time the railway was nationalised in 1978 but in 1999 the Isle of Man Steam Railway Supporters' Association took on the ambitious task of building one of these vehicles from scratch.Through a fund-raising campaign this was achieved and the wagon is now part of the rolling stock of the railing and has been numbered "H.1", being the re-used number of the first vehicle of the class, long since destroyed.This was the second project undertaken by the supporters, the first being the building of a similar vehicle M.78.
