We had a brand new loco to help with the construction of the new line. It is actually on loan to us from Science Projects of Hammersmith and has been constructed in their workshops by one of our members, Dick Scholefield, to his own design.
It is a 0-4-0 petrol engined loco with hydrostatic transmission. It weighs approximately 500kg and is 2.2M long. The engine is a Tecumseh single cylinder 4 stroke of 195cc giving 6HP and is connected to an Eaton Model 7 light duty hydrostatic transmission. The calculated top speed without any load is 7.9mph and it should have a continuous tractive effort of 87kg with 125kg available for starting.
Most of the machine has been built from readily available components although the frame and body have had to be made from scratch.
As all the original locos were named after towns associated with the line ran it was decided to call the new loco “Hounslow” as part of the line runs through that London Borough.
