On May 22 1957, the BBC produced a live television program at the railway. Wynford Vaughan Thomas and Huw Weldon road the train from Dolgoch to Abergynolwyn. As a result of the television program, more people used the train. Over 57,000 people road the train that summer. The money that those people paid helped the Society improve the railway. In 1958, the original "Talyllyn" locomotive was put back in service.
