Experiment was a steam locomotive designed and built by Richard Roberts in 1830 for the Liverpool and Manchester Railway (L&MR). The locomotive had vertical cylinders driving via bell cranks.
[edit] History
L&MR No.32[1] Experiment was built in 1833 with vertical cylinders mounted just behind the chimney, driving the wheels via a bell crank. The locomotive also had piston valves. These valves were probably the reason that the design was not a success, rather than the bell crank transmission, which was used successfully in other locomotives.[2] Another reason that the locomotive was not successful was steam leakage from the cylinders.[1] Experiment was withdrawn after a few months.[2]
Three similar locomotives were built for the Dublin and Kingstown Railway.[1] Locomotives to this design were built for the Dundee and Newtyle Railway, but they were soon altered.[2]
