Hybrid Subway System Transitions Seamlessly Between Suburbs and Downtown
The city of Sheffield in the UK is installing the first tram-train in the country.
The city of Sheffield is installing the first ever tram-train in the UK. A tram-train is a hybrid public transit vehicle that can run both as a street tram servicing commuters in the city center and a commuter train that can use all existing rail network.
Trams and trains run on different kinds of tracks. Tram wheels run inside grooves on tracks — allowing trams to make tight corners. Train wheels, on the other hand, run on top of raised rails. A tram-train has wheels that are designed to work on both types of tracks. This means a tram-train can transition easily from one rail network to the other, eliminating the need for passengers to switch trains during their commute.
