Bryn Tegid

Bryn Tegid is an 009 spiral layout based some where in the mid Welsh mountains. It represents a present day heritage railway which uses small locomotives and short trains on a steeply graded line which incorporates a deviation to avoid a recent road improvement scheme.

The layout has two stations, the upper station is the “original” station site, which was partially excavated in order to create the deviation spiral. This necessitated the construction of a new lower station which has more space for the facilities expected by 21st century customers. The upper station has been retained in a “reduced” form as temporary terminus prior to completion of the final section of the line and for easy access to the mining museum (represented by Chwarel Tegid). The sidings at the station can connect directly to the same incline model which is used on Chwarel Tegid, or a shunting area which at some future point will link to Chwarel Tegid for through running. The Chwarel Tegid cutting shed can also be fitted in this space. I’m also developing a “No. 2” incline based on the restored Vivian quarry incline at Llanberis, which can operate automatically.

The layout incorporates a “(not very) hidden link” which turns the central section of the spiral into a continuous circuit. The link will be hidden by an as yet unbuilt engine shed. Both level crossings have been fully automated and will operate every time a train approaches.

Bryn Tegid – Gravity Slate

This video shows a demonstration slate train hauled in the “up” direction by Quarry Hunslet “Alice” and returning by gravity. The gravity train is actually powered by a tiny motor unit in the gunpowder van!
