The Crystal Palace atmospheric railway
"The Crystal Palace atmospheric or pneumatic railway was built in 1864 at the lower end of the Crystal Palace Park, and was working for a matter of months. It ran for about 600 yards in a 10-ft diameter brick tunnel between the Sydenham and Penge gates to the Park. The tunnel had a gradient of one in 15 and the railway went round in a sharp curve. It had a coach which could seat 35, and a sliding door at each end. There was a remote steam engine coupled to a fan. The railway had a collar of bristles which made it airtight and enabled the coach to be sucked along - at a speed of probably 25 mph. The trip apparently cost sixpence. The engineer was Thomas Webster Rammell, a man behind other pneumatic railway experiments in London. In fact his serious purpose was to design a pneumatic railway to go from Waterloo to Whitehall under the Thames. "
