The Lidingöbanan line is one of Stockholm’s older railways, faithfully serving passengers for almost 100 years, as the first train departed in 1914. Major investments in the Lidingöbanan in recent years show that it is fulfilling at least as important a function today.

The traffic management system for the Lidingöbanan is a good example of how to modernise in small steps and with limited resources. In the first Cactus installation, a workstation was used as the system server. When the line was upgraded in 2013-2015, the traffic control system was also upgraded to a full Cactus TMS.


Proven signalling technology

When the Lidingöbanan line was upgraded, new relay-based interlockings were installed, with Cactus’s own substations to gather indicators into the central system. Axle counters and ATC were also installed on the line at that time. The line is now served by 7 new tramcars of type A36.


A single operator

For the operators responsible for the Lidingöbanan, the system has provided new facilities and improved monitoring. A single operator monitors the Lidingöbanan. This operator can see all of the traffic on three screens, two of them used to provide an overview of the traffic and the third to display other detailed information such as alarms and event logs.

The operator is completely free to choose the monitoring images he or she wants to see.
