Innovative technologies and future trends in the rail industry: insights from Dr Joachim Warlitz

The International Exhibition of Track Technology (iaf) is once again presenting itself as a showcase and a driving force for the rail construction industry. Dr Joachim Warlitz, Vice President of the German Association of the Railway Industry (VDEI) and Head of the VDEI Academy for Railway Systems, provides exclusive insights into the latest developments and challenges in the industry.

Mechanical engineering in focus

This year's iaf puts the spotlight on state-of-the-art mechanical engineering and proven engineering skills. ‘One focus is on optimising track construction using high-performance machines, supported by software and AI-controlled processes,’ explains Dr Warlitz. A noteworthy trend is the extension of product lifetimes through software updates and add-ons, similar to modern automobiles.

Sustainable drive technologies

One significant innovation is dual-system vehicles that can be operated both electrically and with hydrogen. This technology is particularly relevant for tunnel work, where low-emission vehicles improve working conditions. ‘However, we are facing the challenge of developing powerful yet affordable electric motors,’ emphasises Dr Warlitz.

Slab track vs. ballasted track

An exciting topic in track technology is the debate between ballast and slab tracks. The slab track offers advantages such as higher ride comfort, longer service life and lower maintenance. ‘The lifetime of a slab track is around 60 years, compared to a maximum of 40 years for a ballasted track,’ explains Dr. Warlitz. However, the investment costs are higher and subsequent corrections are more difficult.

International perspectives

Germany is considered a pioneer in the use of slab tracks, especially on high-speed lines. In Austria and Switzerland, this technology is mainly used in tunnels. Asian countries such as Japan and China are also increasingly using slab tracks on high-speed lines.

Customer-oriented future

The future of the rail system lies in the seamless integration of different means of transport and the provision of door-to-door solutions. ‘We need intelligent navigation that accompanies the customer throughout the entire journey, even in the event of delays or disruptions,’ says Dr Warlitz. Digitalisation, including AI-supported systems, plays a key role here.

Challenges and opportunities

The iaf highlights the current requirements for track technology machines, including high working speed, precision, multifunctionality and environmental friendliness. The focus is on future-oriented topics such as digitalisation, automation and improved diagnostic capabilities.

Safety as the top priority

Cyber security is an important aspect, as rail infrastructure is considered critical infrastructure. ‘We are operating in an area that is of interest to cyber attackers. Accordingly, highly intelligent and efficient security systems are required,’ emphasises Dr Warlitz.

The iaf once again underlines its importance as an international platform for innovations and future trends in the railway industry. It not only offers an overview of current technological developments, but also shows solutions for the challenges that the industry will have to face in the coming years.
