The County Donegal Railways Joint Committee (CDRJC) constructed the Strabane and Letterkenny Railway. It opened for public service on 1 January 1909 with a route length of 19.25 miles.
It was the last railway constructed by the CDRJC bringing the network operated by this company to 121 miles.
The company pioneered the use of diesel operated railcars, but despite this innovation, closure came at the end of 1959, and the railway was shut on 1 January 1960.
