A train shed is a building adjacent to a station building where the tracks and platforms of a railway station are covered by a roof. It is also known as an overall roof. The first train shed was built in 1830 at Liverpool's Crown Street Station.
The earliest train sheds were wooden structures, often with unglazed openings to allow smoke and steam to escape. The oldest part of Bristol Temple Meads is a particularly fine – and large – example, designed by Isambard Kingdom Brunel with mock-hammerbeam roof.
The middle of the nineteenth century saw many large stations covered by iron, steel and glass train sheds, inspired by The Crystal Palace at The Great Exhibition in 1851. The best have been described as "like cathedrals" and feature curved roofs; other structures have pitched roofs.
Surviving examples of curved roof train sheds include:
After many years with few, if any, significant new train sheds, recent years have seen some major stations given graceful train sheds by using modern technology.
Longyang Road station on the Shanghai Maglev Train line
Gwangmyeong Station, Seoul, South Korea
Jefferson Station, Philadelphia, United States (while station is located underground, it has above-ground structures for the purpose of sheltering the platforms and trains)
Stillwell Avenue subway station, New York City, United States
In the United States, the Walt Disney World Monorail System has some trainsheds along its route, including the entrance-gate station and the main hall (or Grand Canyon Concourse) of the Contemporary Resort.
Open-air canopy
The Union Station (Denver, Colorado), Denver, Colorado, USA features an open-air canopy structure covered with Teflon.
