the ending of evening and Sunday services, the deferral of track maintenance, and cuts to train mileage as locomotives became unserviceable. To further reduce expenses, there were winter closures of the Peel line (1960–61 only) and the Ramsey line after September 1961, but A. M. Sheard, the then general manager, refused to close the Ramsey line which by this time was losing a considerable amount of money each year. Following the closure of the County Donegal Railways in 1960, the IMR purchased the CDR's two most modern diesel railcars, which were then largely used on the Peel line in summer, and after 1962 worked the whole of the winter service except when withdrawn for maintenance. The system closed after the 1965 season but was briefly revived when the Marquess of Ailsa obtained a lease and reopened all three routes in 1967. Both the Peel and Ramsey lines shut following the 1968 season, but goods services between Peel and Milntown (just short of Ramsey) continued until mid-1969. Traffic was poor on the two northern lines, especially that to Ramsey, so after the end of the 1968 season, Ailsa decided to concentrate on passenger service on the South Line for three more seasons until he took the option to end his lease at the close of the 1971 season. There were occasional empty coaching stock workings between Douglas and St John's in 1970 and 1971 for the retrieval of stored stock between seasons. During this time most of the early wooden framed carriages were moved to St John's, where they were lost in a fire in July 1975. The Peel and Ramsey routes and the Foxdale line were lifted in 1975. The IMR operated services between Douglas and Port Erin after Lord Ailsa took his five-year option, beginning in 1972 through the centenaries of the Peel and Port Erin lines in 1973 and 1974 respectively. In 1975, the Port Erin line operated only from its southwestern terminus to Castletown, but it was found that half a railway made twice the loss. The government sponsored a short extension of the service from Castletown to Ballasalla in 1976, and, after extensive campaigning during the 1976 Tynwald elections, the railway returned to Douglas in 1977, the last year in which the railway was operated by the IMR. Following nationalisation the railway has continued to be operated seasonally, for many years from Easter weekend until the
