OpenRail Overhead Line Designer

OpenRail Overhead Line Designer

 OpenRail Overhead Line Designer introduces a new, comprehensive modeling environment for rail overhead line and track design. Developed jointly by Bentley Systems and Siemens Mobility, it combines OpenRail Designer technology with Sicat Master. The application brings 3D to the world of overhead line catenary systems, advancing workflows beyond traditional plan production into the development of digital twins with asset information for the entire lifecycle. Implementation of digital twin technology will significantly decrease production time of construction deliverables, including plan layouts, reports and detailed structural erection diagrams.

OpenRail Overhead Line Designer enables rail designers and engineers to:

  • Design overhead line electrification systems with custom design standards and 3D modeling of wires and structures.
  • Use Siemens Sicat Master functionality for advanced overhead line analysis.
  • Use OpenRail Designer for design of track and corridor models.
  • Bring real-world settings to your project by quickly gathering context data from a variety of sources, such as point clouds, 3D reality meshes, terrain data, images, and geospatial information.
  • Easily share project information across teams, locations, and disciplines with precision and security.
  • Perform regression analysis, horizontal and vertical alignment, cant design, and turnout placement to international standards.
  • Improve asset quality and reduce rework with a fully localized application.
  • Share realistic visualizations with the public and stakeholders to gather feedback, improve public engagements, and speed project approvals.


Rail placement capabilities ensure calculation of precise rail coordinates and joints with track widening tables and cant data. You can also create simple and long sleepers based on your geometry and turnout locations.

Convert surveys of track data into full alignments using regression analysis. Determine the best fit geometry alignment of your track from a range of survey data types, including transition types and cant. You can then use this geometry to produce design changes.

Utilize the Documentation Center for automated production of high-quality drawings, including multi-discipline documentation sets that are consistent across the entire project. Get a live view of the project in sheet orientation. As the design changes, so will the sheets. Make edits directly in the sheets and OpenRail Designer will update the source geometry.

Create profiles and cross sections from any point within the design. View updates on the fly as the design is modified with dynamic cross sections. You can see the ground changing to reflect design edits. Include surface features, corridor components, and notations such as construction limits or stationing.

Use immersive corridor modeling capabilities that support complex modeling and file federation demands required by BIM Level 2 and beyond. Streamline the complex development of every aspect of the railway in a single, parametric presentation. You can move rapidly along a corridor at controlled intervals, viewing and dynamically designing all railway components in concert.

Use local standards and geometry of the underlying track to make span calculations, locate foundation locations, and calculate height and stagger values for your wire runs. Parametric design capabilities enable modeling of cantilever sets, masts, portals, and wires. Produce schematics and 3D models of your OLE system.

​Configure and place signals within a rail model. Build signals interactively from items such as hoods, aspects, and masts. Then use linear referencing to place and orient your signals relative to the track. Geographic and schematic views of the same signal scheme can be produced if required.

Clearly understand existing conditions and accelerate design modeling workflows with the ability to easily integrate imagery, point clouds, and 3D reality meshes into design and construction models. Integrate geospatial information to ensure that models are precisely geospatially located.

Ensuring appropriate drainage is included within rail designs is vital to ensuring the availability of the railway. Preventing storm or floodwater from damaging your rail network through effective design will reduce maintenance costs and increase availability of the network.

Combine survey, design rules, and operational requirements to generate optimal geometry for your track. Use engineering workflows to produce horizontal and vertical alignments and cant design that comply with local design rules.
