Ratty
This home-built petrol-engined inspection car was built by Adam Barber, Simon Newton and others. It has seen a number of reincarnations, and is normally based at the Cambrian Railways Society's Weston Wharf, near Oswestry in Shropshire.
Ratty visited the Quirks & Curiosities event on the FR from 30 April to 3 May 2010.
