A scaled down version of ‘Captain Baxter’, this loco also spent its entire working life at the Betchworth quarry. It was the very first loco to arrive at the Bluebell, but was soon moved on by its owning group, the Narrow Gauge Railway Society, to the more appropriate location of the Brockham Museum Trust, and then in 1982 to the Amberley Museum. Ownership of Townsend Hook was handed over to The Amberley Museum railway project on 26th February 2002. Sadly its unusual gauge means there would be little purpose in restoring the locomotive to working order. The locomotive had been resident at Eastleigh College from 1995, as a long-term restoration project, but is now back at Amberley Museum, with a team of volunteers having undertaken a thorough cosmetic restoration of the components, replacement of missing parts, and re-assembled and repainted the locomotive. More details of the project are available via Townsend Hook’s Facebook page. The photo (with thanks to Amberley Museum) shows No. 4 in June 2016 ready for transport to Tywyn for the ‘Talyllyn 150’ gathering of Fletcher Jennings locomotives, which also involved ‘Baxter’.
