The Signal Box was originally located at the level crossing, Llandrindod Wells, and known as No 2 box. It was dismantled and relocated to its present position on the station platform, formerly the site of the No 1 box.
British Rail handed it over to the Town Council at a ceremony during the Victorian Week in 1990. Since then the Council has opened it for limited periods during the Summer months. It is more than a hundred years old and contains, in exceptionally good condition, many of the original furnishings and machinery.
It is very popular with visitors, particularly during Victorian Week, and the many railway buffs arriving on the special steam trains.
