This station is a request stop used mainly by trekkers and cyclists, since it is the nearest stop to the Sugar Loaf vantage point, although it was originally built to serve a number of cottages occupied by railway workers (such as signalmen and track gangers). The children of the workers travelled by train to school in Llanwrtyd Wells. South of the station the line reaches the summit at above sea level and then passes beneath the hills via the Sugar Loaf tunnel, which is approached by gradients as steep as 1 in 60. It then descends steadily for the next down to . The climb up to the summit here was a challenging one for train crews in steam days (especially northbound) and the use of banking locomotives was commonplace.
