Over in County Antrim there was the 3ft gauge Ballymoney to Ballycastle line run by the LMS (NCC) since 1924, but at one time by an independent company, the Ballycastle Railway. This was a single track line just over sixteen miles in length, running through level country until it came running through level country until it came near the terminus of Ballycastle where there was a falling gradient into the station that spelled disaster on more than one that spelled disaster on more than one occasion. The worst incident was towards the end of the railway's life in 1943, when a train ran out of control through the station and buffer stops, crossed over a road very near a bus stop, went through two fences, and finished up by running down a steep bank into a stream.
One small incident in the life of the Ballycastle line lives on in the memories of the older generation who once worked on it. As with the other more important routes, it was decided that the line should be equipped with mileposts, so that the train drivers would know their location more accurately. Accordingly, a junior member of the LMS (NCC) civil engineer's office was detailed to design suitable concrete posts for this purpose and these were installed one autumn. After a particularly hard winter, an inspector noticed that in place of the mileposts along the track there was now just a series of pyramids of rubble. Apparently, the concrete mix had been of the wrong proportions, and the cold winter had resulted in their almost complete collapse. The Ballycastle line closed on 3 July 1950.
