throughstation

A throughstation is a railway station where trains can pass without stopping, typically because the platforms are located on an island between two main lines. This design allows for continuous movement of trains, increasing the operational capacity of the railway network. Throughstations are common in high-traffic areas or where the need to stop every train is not present, such as on high-speed lines or freight corridors.

The primary advantage of a throughstation is its efficiency. By avoiding deceleration and acceleration for trains that do not require a stop, significant time and energy savings are realized. This is particularly beneficial for long-distance or express services. Furthermore, throughstations can reduce congestion at other stations by allowing trains to bypass them.

In some contexts, a throughstation might refer to a station that is part of a through route, meaning a route that connects two points without requiring passengers to change trains. This contrasts with terminal stations, where trains terminate and originate. The concept of a throughstation emphasizes the station's role in facilitating uninterrupted rail traffic. The design typically involves platforms situated on either side of one or more through tracks, with separate tracks for stopping services if they are also accommodated.
