 "Rocket" passed the trial requirement of achieving an average speed of over by over 40 percent.Demonstrations also saw "Rocket" consistently and easily haul a carriage of over 20 person up the Whiston incline at over , and light engine running of around .No other locomotive at the trials was able to achieve anything like the level of performance reliably, with partners Booth and Stephensons sharing the £500 winnings, and perhaps more importantly the need for stationary engines being demonstrated as unnecessary with sceptics such as Rastrick on the way to conversion.
