SierraSoft Rails is a BIM software for the design of railways for low and high speed, single and double track.

The BIM functions of SierraSoft Rails allow you to produce, modify, share, and analyze railway information models.

Design and information modeling occur simultaneously with a strong optimization of activities and cost containment.

In one product you have all the tools for design, policy control, information modeling and quantities calculation.

SierraSoft Rails is a powerful software that allows you to integrate land surveying work, infrastructure design and construction within the processes, guidelines and tools used for BIM. Information exchange, information modeling, information analysis, and information verification occur through the functionality of BIM software extensions (SierraSoft BIM Modeling, SierraSoft BIM Exchange an SierraSoft BIM Checking)

With SierraSoft Rails you can manage big quantities of data. Your projects will have no limits.

SierraSoft Rails is international by nature and manages different languages (English, Italian, Spanish, Portuguese, German, French) and several units of measure. You can choose different languages among interface, project data and printouts. So you can work in your favourite language and deliver your work in the language that your client wants.

    It is possible to control the design like never before, drastically reduce designing time thanks to 3D real time cross-section on planimetry. By changing a parameter everything is updated automatically. The result can be immediately checked even before creating the final project. Maximum control over the entire design and over every detail.
  • Dynamic engine - The results in real time
    SierraSoft Rails is equipped with a dynamic processing engine, which combined with the parametric engine allows you to obtain complex results in real time and facilitate all design and modeling activities
  • Point clouds: Upload and manage point clouds in a very simple way
    SierraSoft Rails easy handle one or more point clouds of any size. Loading and display are really fast, drawing and extraction functions occur in real time. A special tool โ€œSierraSoft Mass Data Converterโ€ converts LAS, XYZ, PTS, XCF, E57 and DEM GeoTIFF files so that you can manage them with ease.
  • Help: Learning by doing
    Learning tools are included in SierraSoft Rails. The Smarthelp guides the user while working with the software by providing context-sensitive information. The user guide of the product is integrated in the Interface through retractable control panels and always available.
  • BIM Software: Modeling, sharing, checking
    SierraSoft Rails is a powerful software that allows you to integrate land surveying work, infrastructure design and construction within the processes, guidelines and tools used for BIM. Information exchange, information modeling, information analysis, and information verification occur through the functionality of BIM software extensions (SierraSoft BIM Modeling, SierraSoft BIM Exchange an SierraSoft BIM Checking)
  • Mega projects: When size matters
    With SierraSoft Rails you can manage big quantities of data. Only necessary data are loaded into memory and the ones on the disk are automatically compressed in order to create small files. Your projects will have no limits.
  • Policy - Free to design where you prefer
    Calculations, checks and policies checks: SierraSoft Infra Design Studio checks if your project complies with the policy. Check the congruence of the design parameters of the axes with the selected policy. Generate and test the visibility diagram and the speed diagram. Generate the speed diagram. The calculation of the superelevations and widenings takes place automatically. The calculation of the overhangs and widenings takes place automatically. Get a detailed report of the verification, element by element, with the provisions of the policy. The software will suggest, where possible, the maximum and minimum values to be adopted. Several policies are already present in the software, and thanks to an open and intuitive system, you can extend the existing regulations with the new ones you need.

Open Rails features and specs

  • Cost
    Open Rails is completely free to use, which makes it accessible to anyone interested in train simulation without the need for a financial investment.
  • Compatibility
    It supports content from Microsoft Train Simulator, allowing users to leverage existing assets and expand their experience with a wide range of routes and rolling stock.
  • Modding and Customization
    The platform is open-source, which encourages community contributions and allows users to create and share modifications, leading to a diverse range of custom content.
  • Performance
    Open Rails is optimized for modern hardware, offering improved graphics, larger worlds, and better performance compared to older train simulators.
  • Realism
    The simulator provides high levels of detail in physics and operations, which caters to enthusiasts looking for a realistic train simulation experience.

Possible disadvantages of Open Rails

  • Learning Curve
    The complexity of the simulator can be overwhelming for beginners, requiring time and effort to learn and master its features effectively.
  • Limited Documentation
    While there is community support, official documentation can be sparse, making it challenging for users to find guidance on specific features or troubleshooting.
  • Graphical Limitations
    Despite performance improvements, the graphics of Open Rails may not be as advanced as newer commercial train simulators, which could be a drawback for users seeking cutting-edge visuals.
  • Dependence on Community Content
    The quality and availability of content can vary greatly as it primarily relies on community contributions, which may affect the user experience if certain content is unavailable or not up to standard.
  • System Requirements
    Although optimized, users may still need a relatively modern computer to run Open Rails smoothly, potentially excluding those with older systems.

  • New made consists in TSRE or ConBuilder doesn't show in MSTS, any solution for that?
    I recommend getting http://openrails.org/ . It is a free and legal version and with some searching you can find great freeware addons online. Source: almost 3 years ago
  • What train sim should I get?
    How about free. http://openrails.org/. Source: over 3 years ago
  • Best Train Simulators for Budget Laptop
    Give Open Rails a shot! It's continuously being updated, but is also backwards-compatible with original MSTS content which was designed for much older computers. It's quite lightweight as a result, while still allowing for modern content to be developed. http://openrails.org/. Source: almost 4 years ago
