The pneumatic system was intricate: a cast-iron pipe was laid between the railway tracks, and an airtight piston in the pipe was connected to the train. The steam engine at Dalkey pumped air out of the pipe ahead of the train, creating a vacuum; and the atmospheric pressure of the air behind the piston pushed the train along. George Medhurst (–) was a mechanical engineer and inventor, who pioneered the use of compressed air as a means of propulsion. His ideas led directly to the development of the first atmospheric railway. He was born in Shoreham, Kent and trained as a clockmaker at Clerkenwell, London, but later became interested in pneumatics.

In Mendocino County, California, a two-man company hopes to bring to life a new model of high-speed train; one that promises to be greener, lighter, faster, safer and cheaper than any other competitive mechanism currently on the market. George Medhurst (), Civil Engineer of Denmark Street, London, inventor of the Atmospheric Railway. Baptised at Shoreham, Kent, the son of George and Anne Medhurst. Clockmaker at Pleasant Row, Clerkenwell, After the imposition of a duty on clocks had depressed trade, he turned to engineering, working at Battle Bridge, Clerkenwell.
The Medhurst designs were quite advanced for their time, and were an important factor in the decision to purchase the firm. We have Thomas Medhurst’s Pattern Book with his scale designs between and , and also a ‘Catalogue and Description of Medhurst’s Patent Weighing Machines, Cranes, etc’ dated to c Thomas exhibited at the Great Exhibition, and . The Dublin and Kingstown Railway opened in connecting the port of Dún Laoghaire (then called Kingstown) to Dublin; it was a standard gauge line. In it was desired to extend the line to Dalkey, a distance of about two miles. A horse tramway on the route was acquired and converted: it had been used to bring stone from a quarry for the construction of the harbour.

In view of the fact that at many points of the line both the gradients and curves will render the application of this principle particularly advantageous, your directors have resolved that the atmospheric system, including an electric telegraph, should be adopted on the whole line of the South Devon Railway.

23 May The choice of and pneumatic telegraph book atmospheric propulsion system was made after Brunel had seen the atmospheric Samuda and Clegg built Kingston & Dalkley Railway near Dublin in operation. Along with a test line at Croydon, the system had impressed Brunel for him to recommend it to the shareholders of the South Devon Railway.
An atmospheric railway is a railway in which air pressure or vacuum is used to provide power for traction. George Medhurst published, but did not patent, 'A New Method of Conveying Letters and Goods with Great Certainty and Rapidity by Air'. The science of atmospheric power. In this system, a piston (attached to the train) is contained in a large metal tube laid between the tracks.
The tube is evacuated ahead of the train by a series of engine houses (with steam-driven pumps) situated roughly every three miles along the : Philip Strange. Building upon George Medhurst’s last proposal, a number of individuals developed functioning atmospheric railway propulsion systems from the ’s to the ’s, notably the London & Croydon in and Isambard Kingdom Brunel’s South Devon Railway in Exeter.
The success of the 's railways gave rise to the Railway Mania of the 's, when interest in railway shares reached absurd levels. In that climate the proposers of atmospheric lines could find the backing they needed, and four atmospheric lines opened in a period of about 3 years. THE EVOLUTION OF PNEUMATIC RAILWAYS AND THE WORLD’S SECOND UNDERGROUND LINE by Mike Olivier, Long Branch Mike of A report of the LURS meeting at All Souls Club House on Tuesday 9 August Air pressure technology was first tried for railway traction in the s, known as Atmospheric Railways.
An atmospheric railway is a railway that uses air pressure to provide power for propulsion. A pneumatic tube is laid between the rails, with a piston running in it suspended from the train through a sealable slot in the top of the tube.

A typical example is James Pilbrow's proposal for a pneumatic telegraph in combination with an atmospheric railway and canal, see J. Pilbrow, Atmospheric Railway and Canal Propulsion and Pneumatic Telegraph, London, Grenon, Manuel pratique.
45Author: Mustafa Dikeç, Carlos Lopez Galviz. In fact, the Atmospheric Railway was a small train with an experimental pneumatic engine that ran for a few months only, in"between the Sydenham and Penge entrances of the Crystal Palace.
ever built as atmospheric railways. The next atmospheric railway to open actually appeared in. While the atmospheric railways were vanishing, the first pneumatic dispatch tubes were beginning to appear; I'll get into that later. But from that start, the pneumatic railway idea began to return also.
At first these were designed for freight. His first and favourite brainwave was a pneumatically-driven street-car, which failed because the mechanism could never be made leak-proof (for the record, Pilbrow’s Atmospheric Railway and Canal Propulsion Company involved British investors in big losses during the railway.
The London and Croydon Railway (L&CR) was an early railway in England. It opened in and in February merged with other railways to form the London Brighton and South Coast Railway (LB&SCR). /books books Thomas Telford Publishing /tlorselpotiocev The Life of Robert Stephenson, F.R.S.

Atmospheric railways, on which the tube was laid between the rails, with a piston running in it suspended from the train through a sealable slot in the top of the tube, were operated as follows: Dublin and Kingstown Railway's Dalkey Atmospheric Railway between Kingstown (Dún Laoghaire) and Dalkey, Ireland ( mi (3 km)).

Encyclopædia Britannica, Ninth Edition, Volume III — Atmospheric Railway ATMOSPHERIC RAILWAY, a railway in which the pressure of air is used directly or indirectly to propel car riages, as a substitute for steam.
The Atmospheric Railway, on the other hand, could operate virtually silently and run without smoke-belching, spark-spewing locomotives.
Most appealing to Brunel, though, was the Atmospheric Railway's anticipated ability to climb steep grades -- exactly the sort of terrain he was facing along the route of his planned South Devon : Bruce Heydt.
