The Milntown Railway was in fact a short 3 ft (914 mm) narrow gauge spur off the ex Manx Northern line just south of the terminus at Ramsey, Isle of Man. It was constructed only in the final year of operation for the purposes of transporting fuel oil from Peel to Ramsey by rail. The siding was a direct spur off the main line and was on a very tight curve directly into the yard that it served.
