Development

Engineering for the modernisation of existing vehicles as well as for the construction of new vehicles is one of Enotrac’s core competencies. Enotrac has been responsible for a large number of often very extensive projects in both areas. These include flagship projects such as the modernisation of the HGe 4/4 II locomotive of the Matterhorn Gotthard Railway.

Enotrac offers a comprehensive range of services in the field of rolling stock engineering:

• System engineering and electrical engineering
• Concepts and specifications for vehicles and subsystem
• Design and layout
• Design of electrical circuits, creation of circuit diagrams
• Specification or evaluation of components, preparation of lists of equipment and parts for procurement
• Production and installation drawings
• Vehicle documentation, production documentation (e.g. documentation for wiring) and user manuals

For more complex mechanical designs and/or FEM analyses, Enotrac collaborates with accomplished partner companies. Further tasks, such as commissioning and approval, also fall within the Enotrac experts’ area of expertise.

Special customer requirements and needs require individual solutions. Due to the usually very project-specific requirements, these are only produced in small volumes, or even as unique products. In the past, Enotrac has designed and implemented a large number of niche electronic solutions for use on rail vehicles, including, for example, a yaw damper control, the replacement of a mechanical control box with electronic upgrade and teardown logic as part of a driver’s cab modernisation and even an interference current monitoring system.

The products developed by Enotrac are type-tested and comply with all relevant railway-specific standards such as EN 50155 (electronic equipment on rail vehicles), EN 61373 (oscillations and shocks), EN 50121-3-2 (EMC) and EN 45545 (fire protection). Enotrac has a long-standing partnership with Telma AG who support the production of these electronic products.

Enotrac has a highly specialised software development team that is primarily dedicated to the development of in-house applications such as the FABEL simulation software. In special cases, however, Enotrac’s software engineers also apply their skills in customer projects. These are usually niche projects and special solutions that require a strong scientific, mathematical background and specific knowledge of the railway system. Enotrac provides all services from requirements engineering, programming and testing to operation of the software. Enotrac is not a classic software development company, but is supported by accomplished partner companies for larger projects. This means that customers can also rely on the usual high quality of Enotrac’s services in this area.

A prominent example is Switzerland’s national vehicle register, which Enotrac developed for the Federal Office of Transport (FOT) and has been operating as the register manager for many years.
