Siemens Launches Auto Access Ramps for Prague Trams

Post by : Amit

A major leap for barrier-free urban mobility in the Czech capital

In a bold move to redefine accessibility in public transportation, Siemens Mobility has introduced automated folding access ramps in the new fleet of trams deployed across Prague’s urban transit system. The initiative is part of a broader European push to make public transit more inclusive, efficient, and user-friendly—particularly for passengers with reduced mobility, including the elderly, wheelchair users, and travelers with strollers or luggage.

While sleek design and energy efficiency often dominate headlines in next-generation public transport, accessibility has long remained an underserved frontier. Siemens' automated ramp system—now rolling out across the Czech capital—isn’t just about convenience. It represents a fundamental shift toward universal design in transit, one that promises long-term gains in social equity, system usability, and operational safety.

Engineering the Ramp: How Siemens Designed for Real-World Challenges

The automated folding ramp system is more than a retractable platform. Developed by Siemens Mobility’s accessibility engineering team in collaboration with Czech transport operators, the system relies on sensor-assisted deployment that can adjust in real-time to different curb heights, platform slopes, and weather conditions such as ice or rain.

At its core, the ramp mechanism uses hydraulic actuators housed discreetly beneath the tram’s door threshold. These actuators trigger a folding aluminum ramp that extends smoothly onto the platform. A suite of onboard proximity sensors assesses distance and alignment to ensure safe deployment. Importantly, the system can be operated automatically by the tram conductor or manually by staff in special cases.

Unlike older mechanical systems that often broke down or required human assistance, Siemens’ model includes redundant safety locks, motor torque limiters, and machine learning algorithms that detect anomalies in performance. If the sensors detect debris or misalignment, the ramp retracts safely and alerts the driver.

Focus on User Experience: Seamless Boarding for All

Perhaps the most impactful feature of Siemens' new ramps is how invisible they feel to regular riders—and how empowering they are for others.

For wheelchair users, the previous boarding process involved operator intervention or assistance from other passengers. Now, boarding is fully autonomous. Riders press a designated accessibility button on the tram’s exterior, which triggers the ramp's deployment in less than six seconds. For the elderly or parents with strollers, it reduces physical strain and waiting time.

Internally, the floor of the tram aligns seamlessly with the extended ramp, removing awkward elevation changes that often cause trips or discomfort. The flooring is coated with anti-slip material, and yellow tactile edges offer visual cues for those with low vision.

Urban Transit Transformation: Prague Sets a New Benchmark

Prague has long been admired for its charming historic trams and scenic routes. But for decades, critics argued that its public transit infrastructure excluded a significant portion of its population. With over 900,000 daily tram riders, including thousands of older citizens and tourists, accessibility gaps became increasingly visible—especially on routes serving hospitals, schools, and major tourist destinations.

This deployment changes that. Siemens’ new ramps are already in use on select lines including Line 17 and Line 9, which traverse both hilly terrain and major commuter hubs. The Prague Public Transit Company (DPP) has committed to retrofitting 35 additional new trams over the next 18 months and has hinted at integrating similar accessibility features into buses and metro systems.

According to Martin Gillar, CEO of DPP:

“This is not just an upgrade; it’s a statement of inclusion. With Siemens, we are building a transport network that treats all riders with dignity and independence.”

Regulatory Push: Aligning with EU Accessibility Mandates

This innovation also arrives at a time when European Union mandates are forcing public transport agencies to comply with new accessibility guidelines under the European Accessibility Act and UN CRPD (Convention on the Rights of Persons with Disabilities). By 2025, all new rail and tram infrastructure in EU member states must provide inclusive boarding, visual and audio information, and obstacle-free access.

Siemens’ ramp system is fully compliant with EN 14752 standards for accessibility on low-floor trams and adheres to IP54 weatherproofing regulations. Its rollout in Prague is being hailed as a case study in early adoption of these requirements—positioning Czechia as a regional leader in inclusive mobility.

A Race Toward Smarter, Safer Access

While other OEMs such as Alstom and CAF have experimented with similar concepts—CAF recently began testing AI-controlled vestibule sealing mechanisms in Oslo—Siemens' focus on real-time terrain detection and autonomous deployment gives it a technological edge.

Moreover, by integrating ramp diagnostics into the tram’s central fleet management dashboard, operators receive predictive maintenance alerts and performance data. This reduces the likelihood of breakdowns, a major concern in cold or wet seasons that affect mechanical systems.

In the long term, Siemens plans to extend this ramp technology to other vehicle types, including electric city buses and intercity light rail, signaling a broader strategic shift toward intermodal accessibility solutions.

Voices from the Ground: What Riders Are Saying

Feedback from passengers during early trials has been overwhelmingly positive. Katerina Hruba, a wheelchair user and Prague resident, said:

“For the first time, I didn’t need to ask for help or wait. I felt independent and respected. It might sound simple, but it changes everything.”

Meanwhile, parents, elderly riders, and even cyclists have embraced the ramps as a long-overdue convenience.

According to Zdenek Komarek, a conductor on Line 17:

“We’ve had fewer delays, less stress during boarding, and happier riders. It’s a small piece of tech that makes a big difference.”

Could This Be a Model for Other Cities?

The success of Siemens' automated ramps in Prague could very well become a blueprint for other European cities seeking to modernize outdated systems. Cities like Budapest, Bratislava, and Zagreb have similar legacy tram infrastructure and are under pressure to comply with EU accessibility norms.

By combining cutting-edge mechanics, user-centered design, and regulatory foresight, Siemens has demonstrated that making transit inclusive doesn't mean compromising efficiency or aesthetics. On the contrary, it enhances the public image of the system and builds long-term civic trust.

The future of urban mobility won’t just be electric or autonomous—it will also be accessible by design.

A Ramp Into the Future

As cities race toward climate goals and digital transformation, accessibility can no longer be an afterthought. Siemens’ automated folding ramps mark more than a technical milestone—they symbolize a cultural shift in urban mobility where no one is left behind.

With Prague leading the way and Siemens setting the standard, a more inclusive transportation future is not just imaginable—it’s already boarding.
