Lethbridge Viaduct
The Lethbridge Viaduct, commonly known as the High Level Bridge, was constructed between 1907 and 1909 at Lethbridge, Alberta, Canada at a cost of $1,334,525. Overview This massive steel trestle over the Oldman River was designed by the Canadian Pacific Railway's bridge department in Montreal, Quebec. The field work was directed by CPR's Assistant Chief Engineer John Edward Schwitzer. The steel work was manufactured by the Canadian Bridge Company of Walkerville, Ontario. A 100-man gang worked on the erection of the steel. Although there were some initial problems with settlement, the bridge has proved to be an enduring engineering work and is still in use today. This bridge is the largest railway structure in Canada and the largest of its type in the world.Viaduct Facts history It was built as ...

Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...
