Electric Heritage, Sustainable Future: Prague's Trolleybus Revival and Electrobus Strategy
Prague is bringing trolleybuses back and expands its electric transit legacy—metro and trams—with dual-pole charged e-buses and partial trolleybuses to decarbonize hilly routes. A smart, clean and sustainable solution rooted in tradition.
About this Project
Prague’s hilly terrain challenges full electrification of bus transport. While metro and tram networks are already electric, many bus routes remain diesel-powered.
Our solution introduces dual-pole charged electric buses and partial trolleybuses, enabling clean mobility even on steep routes. It revives trolleybus infrastructure in a modern form, using overhead wiring only where needed.
Two lines are already in operation, including a double-articulated trolleybus to the airport under the eBRT 2030 project. Several more lines are in preparation, with additional launches planned for 2026.
This complements Prague’s electric transit legacy and supports climate goals by reducing CO₂ emissions and improving air quality.
Synergy effect brings connection to the tram wiring infrastructure and recovery energy in metro and tram sector while braking or descending hills.
Key Highlights
Prague’s project innovatively revives trolleybuses with dual-pole charging and partial overhead wiring, enabling zero-emission operation in hilly terrain. It complements the city’s electric metro and tram networks, which already feature regenerative braking.
This recovered energy is used to charge trolleybuses and e-buses, creating a smart, circular energy system. Two lines are in operation, including a double-articulated trolleybus to the airport under eBRT 2030, with more planned by 2026. The modular infrastructure and synergy with existing systems make it a scalable model for sustainable urban transit.
Facts & Figures
- Two lines already operate with zero-emission trolleybuses and e-buses, replacing diesel vehicles.
- The airport line (eBRT 2030) uses double-articulated trolleybuses. CO₂ emissions reduced by up to 90% on converted routes
- For example only 14 e-buses in length 12m saves 252,000 liters of diesel and 71 tons of CO₂ annually.
- Regenerative energy from metro/trams powers charging. More lines launch in 2026, expanding impact.
