This is RTV 31 (Research Test Vehicle) propelled by a Linear Induction Motor (LIM) along a concrete guideway. On 7 Feb 1973 RTV 31 reached a speed of 104 mph (167 km/h) on a one mile section of test track. Just a week later funding for the project was cancelled. In 1996 Railworld, next to the Nene Valley Railway Peterborough station, acquired RTV 31 and placed it on display.
