An Encyclopedia of the History of Technology part 59. This one of a kind encyclopedia presents the entire field of technology from rudimentary agricultural tools to communication satellites in this first of its kind reference source. Following an introduction that discusses basic tools, devices, and mechanisms, the chapters are grouped into five parts that provide detailed information on materials, power and engineering, transportation, communication and calculation, and technology and society, revealing how different technologies have together evolved to produce enormous changes in the course of history | PART THREE TRANSPORT Evidently Seguin quickly discovered their inadequacy for he too was soon using exhaust steam to draw the fire. Americans too were at this stage closely observing railway development in Britain. In 1829 Horatio Allen obtained the locomotive Stourbridge Lion from Foster Rastrick Co. of Stourbridge. Her sister locomotive Agenoria is now the oldest locomotive in Britain s National Railway Museum. She was intended for a railway belonging to the Delaware Hudson Canal Co. but on trial she caused excessive damage to light track laid with wooden rails and iron straps and was not put into regular service. The mainstream of locomotive development continued to be that of the Stephensons in Britain. Rocket s cylinders were originally inclined at about 45 which enabled her to be carried on springs but she was still cumbersome at speed. The cylinders were soon lowered so as to be nearer horizontal. Then in 1830 Robert Stephenson designed the locomotive Planet for the L MR with cylinders positioned horizontally beneath the smokebox and drive from the connecting rods to a crank axle. In its layout Planet was the ancestor of all later conventional steam locomotives. THE RAILWAY AT WORK The Liverpool Manchester Railway was opened on 15 September 1830. It had been promoted to carry freight between the growing port of Liverpool and the growing industrial town of Manchester but it was in fact as a passenger carrier that it saw great and near-instant success. Britain at this period was crisscrossed with a highly developed network of horse-drawn coach services over the previous fifty years improvements to the roads and in administration of coaches had halved journey times see Chapter 8 . Coaching was an effective and admired means of transport for passengers and mails. Yet however good the administration however smooth the roads coaches could never exceed the speed of galloping horses which in practice allowing for halts to change horses every ten miles or so meant .
