Knockcroghery, Co.Roscommon, is located west of Athlone on the Mayo line to Westport. The line was first opened by the Midland Great Northern Railway in February 1960, who were taken over by the much larger Midland Great Western Railway. Knockcroghery station was closed in June 1963, but the station remained a block post with the signal cabin controlling the loop and crossing gates. Recently however, CTC has been introduced on the Mayo line rendering the mechanical signalling redundant. The station building at Knockcroghery is semi derelict, but retains both its up & down platforms. CTC has also re-aligned the passing loop away from the level crossing to allow new automated one to be installed. The signal cabin is of MGWR origin, and is built in brick similar to Castlebar's and others on the Mayo line.
