Mineral revenue was about twenty times the value of passenger receipts, and the latter declined further in the 1920s and 1930s as reliable road transport was developed. While railways had an inherent advantage in transporting heavy minerals, the line's viability was dependent on the commercial success of local quarries, and when this declined the finances of the line became irretrievable. Glanyrafon station opened soon after the opening of the line. The passenger train service in 1922 consisted of three trains each way between Oswestry and Llangynog, with an extra train on the first Wednesday of the month. The Glanyrafon stop was by request only. In July 1938 the service was more complicated: successive trains ran from Oswestry to Llangynog respectively on Wednesdays; daily except Wednesday and Sunday; Monday, Tuesday and Friday; Wednesday Thursday and Saturday; daily except Saturday and Sunday; on Saturday only; and on the first Wednesday of every month, but also on 30 July. The return service was a little simpler, running respectively on Wednesday; weekdays only; weekdays only; Monday to Friday; and Saturdays only. By this time the Glanyrafon stop had become definite. Absorbed by the Cambrian Railways Opening its line in 1904, the Tanat Valley Light Railway Company was in the hands of the receiver continuously from that year, as its income did not enable it to pay the interest on loans. The Cambrian Railways subsidised it, but by 1921 it was obvious that improvements to the track and bridges were required, and this was beyond the financial resources of the bankrupt company. Takeover by the Cambrian was the only way out, and this was authorised by Order of the Light Railway Commissioners. The Cambrian Railways were themselves taken over by the Great Western Railway the following year. Closure Passenger services were discontinued on 15 January 1951. The line west of Llanrhaiadr was closed completely in July 1952, a residual goods service continuing as far as that point for the time being. The line closed completely in December 1960.
