The Conwy Valley Railway Museum () is located at Betws-y-Coed railway station, Betws-y-Coed, North Wales, on the site of the old railway goods yard.
Museum
The museum was founded starting with a former standard gauge railway carriage which today acts as a licensed buffet and restaurant car. The current museum was built later, and contains various railway artefacts.
Miniature railway
Other attractions include a gauge miniature steam railway which runs for on the site. The railway is a single track running around the perimeter of the site. It is curved round 180 degrees at the South of the site with a balloon loop at each end which are superimposed at the North of the site. Use of several spring points allow trains to complete a circuit without manual adjustment of any points. Passing loops allow more than one train to use the circuit simultaneously.
Tramway
There is also a one-third full-size (1:3) electric tramcar which runs for a on the site, on track of gauge. This is one of only two electric tramways in Wales (the other being a short gauge electric tramway in Heath Park, Cardiff, owned by Cardiff Model Engineering Society).
