The National Traction Engine Trust's "Steam Apprentice Club" present their "Formula Mamod" track at the 2023 County of Salop Steam Engine Society's "Shrewsbury Steam Rally" held at Onslow Park.
They do them as time trials if people want to take their own Mamon along to 'race'. On occasion will run two together at opposite ends of the track - obviously if one is faster then it will gradually catch the other up. It's all great fun to watch 😃
