Cross-platform interchange
Encyclopedia
A cross-platform interchange is a type of interchange
Interchange station
An interchange station or a transfer station is a train station for more than one railway route in a public transport system, and allows passengers to change from one route to another. Transfer may occur within the same mode, or between rail modes, or to buses...

. Building a cross-platform interchange may be costly due to the complexity of railtrack alignment, especially so if the railway operators insistently arrange their track without flat crossings. A common two-directions cross-platform interchange configuration consists of two selected directions of two different lines sharing an island platform, and each return directions of both lines sharing another island platform in the same station complex.

Types of cross-platform interchanges

Types of cross-platform interchanges describe which trains shall be interconnected cross-platform.

Cross-platform interchanges between different lines

Common cross-platform interchanges allow passengers to switch directions without changing to another platform between trains. This applies nearly everywhere, where trains of different directions meet in minor and major hubs, but is only found at selected interchange stations in the metro networks worldwide.

Cross-platform interchanges between different train categories

Some railway lines usually in more congested areas offer cross-platform interchanges also between different train categories, for example between express and stopping trains. Generally, this kind of interchange is used in many European railway minor hubs to connect fast trains to local feeder services as well as on surface sections of suburban lines like RER E

.

As express and stopping trains usually head for different directions, cross-platform interchange between different train categories is commonly combined with the one between different lines.

Levels of cross-platform interchange connection

Levels of cross-platform interchanges describe how the trains are connected by timetable or not.

Uncoordinated cross-platform interchange

Basically, cross-platform infrastructure only offers the possibility of easy changing of trains independently from the waiting time for the second train. This is the basic infrastructure approach without taking timetables into account. While in metro systems with short headways, waiting time is small, an uncoordinated approach could waste the advantages of stepless cross-platform interchanges in railway networks with less dense train traffic.

Coordinated cross-platform interchange

More advanced is to coordinate the lines' timetables

 railway networks, where trains of different lines meet at same platforms in numerous hubs all over the country.

Optimised cross-platform interchange with connection guarantee

Most advanced are coordinated cross-platform interchanges if interconnected trains also wait for each other to guarantee scheduled interchanges also in case of delays. In order to still ensure on-time running across the network, additional waiting time for trains is usually limited to a certain period of time depending on general network performance, further connections to be guaranteed, train category, train line and/or to which hub this shall apply.

In reality, most railways coordinating cross-platform interchanges define a certain waiting time depending on each guaranteed interchange. Some railway infracture managers don't clear the exit signals before interchange took place; Vienna

, cross-platform interchange stations first appeared at Mong Kok and Prince Edward stations when Tsuen Wan Line was opened. The interchange is two stations long, with inverse cross-platform interchange assigned to Prince Edward and same-direction interchange to Mong Kok as large volumes of traffic had been anticipated in both modes. Popular with passengers, this design was repeated on Admiralty Station when the Island Line was opened to deal with the heavy opposite-direction interchange anticipated. Years later, another interchange spanning Tiu Keng Leng Station (same direction) and Yau Tong Station (opposite direction) was built to the same configuration as Mong Kok and Prince Edward (see diagram). The interchange from Ma On Shan Line to East Rail Line is so designed that trains on the Ma On Shan Line observe right-hand traffic rules, unlike other road or rail traffic in Hong Kong. This cross-platform arrangement between southbound trains of the two lines creates convenience for most morning commutes. Another configuration found in Lai King Station makes commute in both directions more convenient by aligning both tracks leading towards city next to each other on one level, and both tracks leading away from city next to each other on the other level. By connecting East Rail and West Rail lines at Hung Hom without through-running, both lines terminate there alternating on both East/West Rail platforms to offer cross-platform interchanges.
