Yeo was one of three narrow gauge 2-6-2T steam locomotives built by Manning Wardle in 1898 for the Lynton and Barnstaple Railway.

It had been intended that Lyd would receive Yeo's original chimney (which survived on a steamroller for 62 years) but it was found to be too corroded for further use.

[3] A set of frames for a new Yeo were built by Winson Engineering in 2000 and are currently stored waiting for construction to continue when funds are available.

[7] A 12+1⁄4 in (311 mm) gauge model was built by David Curwen in 1978 for the Réseau Guerlédan Chemin de Fer Touristique in Brittany, France.

[8] A 7+1⁄4 in (184 mm) gauge model was built by Milner Engineering in 1979 and worked in Buckfastleigh before moving to the Gorse Blossom Railway in 1984.
