Olskroken is one of the most important infrastructural nerve centres in the rail system of Sweden. To support the vast infrastructural needs, Trafikverket has put one of the largest projects in Sweden out to tender. The objective of this project is to re-organize the entire nerve centre which handles a train passing every two minutes.
An essential challenge during the execution of this project is that the railway will be in operation during the entire process. This puts a lot of pressure onto the railway monitoring requirements, in that the winning contractor has to assure a safe track for the passing trains. Traditional monitoring methods are not an option due to two primary reasons: the operating railway and the need for frequent measures.
The winning contractor of the project, valued at 2,9 billion Swedish Crowns, is PEAB, together with the subcontractors WSP and Infranord. The project began early 2018 and is expected to last until 2025.
Railmonitor supports the track monitoring
To support the monitoring of the tracks, Railmonitor has delivered a truly wireless solution. In order to ensure a continuous and adequate condition monitoring it consists of 166 reliable and robust wireless tilt sensors. The sensors are installed on several parallel tracks from where they are sampling and sending out data per 15 minutes. The sensors are monitoring the condition of a track section of one kilometre altogether.
As part of the truly wireless solution, a battery-powered gateway (LH) is installed nearby the sensors. Solar cells (RH) charge the battery.
Railmonitors condition monitoring platform assures PEAB an easy access to all of the measured data in the intuitive user interface. From here, they can get a quick overview of the track condition in real-time. Furthermore, all of the data is being processed and fully exploited which makes it possible to get an insight of changes in cant, twist, slope and bend.
When the changes exceed the allowable thresholds, warnings are immediately sent out to all the relevant people in the form of SMS and e-mail. When needed, PEAB easily can devise condition reports in PDF format which can give relevant collaborators and authorities a current status of the track condition.
The system assures that PEAB, together with Trafikverket, has a constant insight into the track condition. This makes it possible for them to meet the strict monitoring requirements for the railway, that will be in constant operation.
