The electrictelegraph was patented by Cooke and Wheatstone in 1837, and in 1839 theysecured its introduction to govern the train service on the Great WesternRailway (England). The movements were telegraphed from station to sta-tion, and a train was not allowed to leave a station until the preceding trainhad passed the next station in advance. This was the beginning of the block system, which is a great element in the safe operation of traffic, sinceit maintains an interval of space between trains. Mr. Edwin Clarks tele-graph block system was introduced in 1853, and as traffic increased interme-diate block signal stations were established between the regular stations, soas to shorten the distances between trains. This system is compulsory inGreat Britain and is already largely used in the United States. It was at. AN AMERICAN EXPRESS LOCOMOTIVE. first held that it was not adapted to conditions in this country, where somany lines have but a single track, but experience has shown that it increasesthe facility as well as the safety of operating traffic on single and doubletrack lines alike. Steam locomotives were used on colliery railways in England as early as1804, when Trevithick built an engine, which was the first to haul a train onrails. George Stephenson built his first locomotive in 1814, and in 1825 builtthe Locomotion for the Stockton & Darlington Railway.
