The History of Railroad Innovations

Roads of rails called Wagonways were being used in Germany as early as 1550. These primitive railed roads consisted of wooden rails over which horse-drawn wagons or carts moved with greater ease than over dirt roads. Wagonways were the beginnings of modern railroads.

By 1776, iron had replaced the wood in the rails and wheels on the carts. Wagonways evolved into Tramways and spread though out Europe. Horses still provided all the pulling power. In 1789, Englishman, William Jessup designed the first wagons with flanged wheels. The flange was a groove that allowed the wheels to better grip the rail, this was an important design that carried over to later locomotives.

The invention of the steam engine was critical to the invention of the modern railroad and trains. In 1803, a man named Samuel Homfray decided to fund the development of a steam-powered vehicle to replace the horse-drawn carts on the tramways. Richard Trevithick (1771-1833) built that vehicle, the first steam engine tramway locomotive. On February 22, 1804, the locomotive hauled a load of 10 tons of iron, 70 men and five extra wagons the 9 miles between the ironworks at Pen-y-Darron in the town of Merthyr Tydfil, Wales to the bottom of the valley called Abercynnon. It took about two hours.

In 1821, Englishman, Julius Griffiths was the first person to patent a passenger road locomotive.

The History of Steam Engines

Inventors: Thomas Savery, Thomas Newcomen, James Watt

Thomas Savery (1650-1715)

Thomas Savery was an English military engineer and inventor who in 1698, patented the first crude steam engine, based on Denis Papin's Digester or pressure cooker of 1679.

Thomas Savery had been working on solving the problem of pumping water out of coal mines, his machine consisted of a closed vessel filled with water into which steam under pressure was introduced. This forced the water upwards and out of the mine shaft. Then a cold water sprinkler was used to condense the steam. This created a vacuum which sucked more water out of the mine shaft through a bottom valve.

Thomas Savery later worked with Thomas Newcomen on the atmospheric steam engine. Among Savery's other inventions was an odometer for ships, a device that measured distance traveled.

Thomas Newcomen (1663-1729)

Thomas Newcomen was an English blacksmith, who invented the atmospheric steam engine, an improvement over Thomas Slavery's previous design.

The Newcomen steam engine used the force of atmospheric pressure to do the work. Thomas Newcomen's engine pumped steam into a cylinder. The steam was then condensed by cold water which created a vacuum on the inside of the cylinder. The resulting atmospheric pressure operated a piston, creating downward strokes. In Newcomen's engine the intensity of pressure was not limited by the pressure of the steam, unlike what Thomas Savery had patented in 1698.

In 1712, Thomas Newcomen together with John Calley built their first engine on top of a water filled mine shaft and used it to pump water out of the mine. The Newcomen engine was the predecessor to the Watt engine and it was one of the most interesting pieces of technology developed during the 1700's.

The Ambarawa Railway Museum

The museum was established in the 1970s primarily to preserve a wide selection of the steam locomotives which were then coming to the end of their useful lives on the 3ft 6in (1067mm) gauge railways of the Indonesian State Railway (the then Perusahaan Negara Kereta-Api, PNKA). These are parked in the open air next to the original station, originally a transhipment point between the 4ft 8½in gauge branch from Kedungjati to the north-east and the 3ft 6in gauge line onward towards Yogyakarta via Magelang to the south. It is still possible to see that the two sides of the station were built to accommodate different size trains.

Ambarawa lies some way above sea level and was an administrative centre for the Dutch colonialists. It is now a popular area for local tourists, particularly with the nearby hill station of Bandungan and the Hindu-Buddhist temples at Gedong Songo. Foreign tourists pass through the area particularly in conjunction with visiting the Buddhist temple at Borobudur. Hence the museum is well situated and its development into a world class site is not only desirable but feasible with the right kind of backing. Currently it is still part of the State Railway who have supported it to the best of its ability since formation although funding has never been generous.
