Lidingöbanan

Lidingöbanan is one of Stockholm’s older railway operators and it has faithfully served passengers for nearly a century. In 1914, the very first train departed, and though many aspects are still unchanged, technology and the trains themselves have evolved.

The traffic management system used by Lidingöbanan is a great example of how operations can be modernised gradually, and by simple means, such as using a single workstation that also doubles as a server.

A mixed technical environment – in every way
In addition to this, Lidingöbanan is a great example of Cactus’ ability to merge old and new technology, and create a working blend of different makes of equipment. The system features a central relay interlocking system with a main control PLC. Along the line, there are relay interlocking stations that accept orders and submit indications via a Dupline system.

A single dispatcher
The dispatching routines at Lidingöbanan were transformed by the new Cactus traffic management system.

A single dispatcher was now able to supervise the entire Lidingöbanan line. All traffic along the line is easily monitored by way of two screens. One screen is generally used to display a general view of the entire line, while the other is generally used for more detailed information. However, dispatchers have the option to select the views they need.

Another useful feature is that the detailed views are scrollable, using a ruler feature at the bottom of the display. This enables dispatchers to easily scroll down to the section of the line they would like to obtain more detailed information about.
