The Trolleybuses Returns to Tallinn

Why It Matters

Restoring trolleybus service strengthens Tallinn’s commitment to low‑emission public transport, improving urban mobility and meeting EU climate targets. The timely rollout also showcases the viability of large‑scale electric bus procurements in mid‑size European cities.

Key Takeaways

• First of 40 new trolleybuses ready for testing
• Fleet will replace aging 49 vehicles from 2002‑2010
• Deliveries start May 2026; service resumes on four lines
• 12‑m and 18‑m models built by Škoda with SOR bodies
• Project stays on schedule, supporting Tallinn’s electric transit goals

Pulse Analysis

Tallinn’s trolleybus network, suspended in 2024, is poised for a comeback as the city invests heavily in electrified public transport. The decision aligns with a broader European push toward zero‑emission mobility, driven by stricter emissions regulations and growing public demand for sustainable travel options. By reintroducing trolleybuses, Tallinn not only reduces its carbon footprint but also revitalizes a historic mode of transport that offers high passenger capacity and lower operating costs compared with diesel buses.

The new fleet consists of 18 twelve‑metre and 22 eighteen‑metre articulated trolleybuses built by Škoda with SOR bodywork. These models, designated 32 Tr and 33 Tr, feature modern power electronics, regenerative braking, and energy‑efficient motors that can adapt to Tallinn’s traffic patterns. With deliveries scheduled to start in May 2026, the first vehicles will undergo extensive spring testing to verify reliability and energy performance. Once operational, the upgraded fleet will replace the older 49‑bus stock, many of which are nearing the end of their service life, thereby improving service frequency and extending operating hours from early morning to midnight.

The revival of trolleybus service carries significant economic and environmental implications. Faster, more reliable electric buses can attract riders back from private cars, easing congestion and lowering urban pollution levels. Moreover, the project demonstrates the scalability of electric bus procurement for cities of Tallinn’s size, potentially influencing neighboring municipalities. As infrastructure upgrades near completion, the city is set to meet its EU climate objectives while delivering a modern, resilient public‑transport system that could serve as a model for other Baltic capitals.
