 However, these changes arrived too late to be of much use; the tractor arrived 7 months later, and the new wagons did not start arriving until May 1955.That same month, the Progress League conceded that the guarantees would not be honoured, with only 12,500 of the promised 28,815 carried to date.Though the performance of the railway did improve, it was not enough, and on 15 August 1955 the Prime Minister announced that the railway would close on 3 September.
