Introduction of High-speed rail(高速铁路概论) Unit 1 Stations, lines and turnouts 1-1.ppt

To complete the above-mentioned activities, at intermediate stations, there are different tracks, for example, arrival and departure track, lead track and freight track, passenger transport facilities, i.e., station buildings, passenger platform, canopy and crossing equipment, as well as freight transport facilities like warehouse, freight platform, loading and unloading machinery. 2. District Station Most district stations are found in medium-sized cities or at the start or end of locomotive traction section (routing of passenger or freight locomotives). At these stations, some or all the locomotives of trains running through adjacent sections are changed and locomotive crew shifted. Furthermore, the stations may be tasked with certain technical operations for transit trains without resorting, a certain volume of break-up and resorting of freight trains and passenger and freight transport.

Marshalling station Marshalling station is often arranged at the junctions of several main lines in the railway network and equipped with a complete set of shunting facilities to disintegrate and marshall large number of freight trains. Discussion 3 1.Why should freight trains be disintegrated and marshalled? 2.Will all freight trains be disintegrated and marshalled? shunting yard hump camel platform of hump crest Pushing section part rolling section part Hump is shunting equipment for disintegrating freight trains.
