The layout depicts the building of a dam in Wales around the turn of the last
century. It includes the massive dam wall, which is in the near completed state
with cranes on the top and an authentic temporary tunnel through to the far side.
A tall ‘Blondin’ crane is located just behind the dam to bring materials to the top.
Further travelling and swivelling cranes work on their own broad gauge line at the
top of the dam.
The stone quarry and dressing shed are the source of materials and the line zig-
zags up the confines of the valley side to gain access to the plant for mixing
cement and stone crushing. The high line also provides access off-scene to the
interchange with the mainline much further down the valley and access to other
dams being built further up the valley.
Down by the river the workers accommodation, school and chapel together with
their water supply are modelled.
The rock faces and the realistic scenic work are appreciated by many who study
the layout and help set the scene of the little engines making their way up the
The model was inspired by accounts and pictures of the dam building in the Elan
Valley and at Grwyne Fawr near Abergavenny, these dams and reservoirs are
still in use and evidence of the railways and the works and buildings can still be
seen. These projects used the temporary heavy transportation of the time -
narrow gauge railways with steam engines. Also they were very long term
projects in remote locations and required that the workers and their families lived
on the site. Typically a school, a hospital and a chapel were provided in addition
to their living accommodation as some of these villages existed for 20 years.
