Temporary Speed Restrictions (TSRs)

Temporary speed restrictions (TSRs) may be required in order to ensure the safe operation of your rail network, which can have a major impact on operations and revenues.

The WillowTwin™ for Rail platform has features that allow its users to see the location and number of speed restrictions currently affecting their network. As well, additional information related to TSRs is also accessible in order to help determine the root cause of each restriction and identify the best course of action for maintenance and the ultimate removal of a TSR.

TSR information can be viewed in various places in your twin, including:

  • Map panel
  • Asset details
  • Performance > Restrictions dashboard

TSRs Map Layer

Whether on the Assets, Ticketing, and Performance tabs, users can enable views of TSRs on their map by clicking either the enabling the TSRs layer from the Map filter menu. From here users will have the ability to filter by:

  • Status
  • Type
  • Group Cause

As well as configure the display to show:

  • Point Clusters (historic + current)
  • Type (cluster)
  • Type (line)


Users can view areas of temporary speed restrictions on the map by enabling the layer from the map filters:

TSR Reports & Metrics

The performance tab provides users with a dashboard and summary of the temporary speed restrictions that have occurred over time. Divided into 3 sections users will see:

  • TSR metrics
  • TSR Map
  • Summary Graphs & Table data


Users will find the same TSR filtering and display options described in the Map filter section also apply here, however, those filters do not apply to the summary graphs or table data displayed just below the map. The table data visible on the Temporary Speed Restrictions tab in the bottom 3rd section will display all TSRs, each column includes an option to sort the data or to filter the data as needed.
