At the end years 1820, Gurney worked on a more viable project and consisting in one before steam-powered, light train, to four wheels, foreseen to pull a tows would take places passengers where.
August 12, 1829, to Hounslow, the limber was harnessed to a convertible where to four rooms represented among other personalities, the duke Wellington (the winner of Napoléon Ier to Waterloo in Belgium) and Stephenson Robert (the author of the island to the treasure).
The car of compact and light shape was used like car deprived by George Cayley (the father of the British aeronautics) that finishes one day by striking a shop window of a store.
In 1830, the vehicle of Gurney was equipped of wheel to full disk in order to value traction on railroad track, it only succeeds in extricating 20 tons to the speed of 8km/h.
In 1831, a named Ward conceived the project of passenger's regular service in the region of Glasgow, he asked Gurney to send a vehicle that he would buy. But Gurney committed the mistake to send him by boat instead of to bring of it to him by the road, and besides, it was necessary him, once to arrive to harness it to bring up a coast, so that scared Ward gave up his project and Gurney came back with his machine.
Still in 1831, sir Charles Dance proposed a regular service between Gloucester and Cheltenham, and ordered three limber to Gurney that only delivered an of it. The car functioned 4 months then its axle broke himself on a heap of stone that was maybe due to a sabotage of diligence owners that believed of a bad eye the arrival of these machines to steams.
At the time of the accident, it had done 396 journeys for a whole of 5840 km, either the third of that that was foreseen; one can think therefore that there were a lot of mechanical boredoms.
