Trolleybuses: Wires becoming charging infrastructure for in motion charging

State-of-the-art in motion charging (IMC) trolleybuses present many opportunities for cities. This Knowledge Brief aims to show cities how their existing trolleybus technology can be advanced with emerging IMC technology to ensure the application of efficient, functional, trouble-free solutions proven in large-scale, real-life operational contexts.

Furthermore, reaching zero-emissions goals can happen much faster in cities deploying IMC technology, since IMC buses scale very well.

This publication follows from the Knowledge Briefs “In Motion Charging Innovative Trolleybus”, published in 2019, and the “Infrastructure for In Motion Charging trolleybus systems” from 2021.

The Knowledge Brief has been compiled by UITP’s Trolleybus Committee. In expressing our gratitude, we wish to extend special acknowledgment to the late Jiří Kohout, who served as the Trolleybus Committee Chair and Head of Transportation at PMDP in Pilsen.

Jiří was not only a dedicated champion of public transport but also a highly esteemed member of UITP. The invaluable contributions made by him during his tenure, including his pivotal role in shaping this report, stand as a testament to his knowledge, guidance, and support. Many significant milestones, such as the completion of this report, were achieved under his leadership, and his legacy continues to inspire our commitment to advancing public transportation.
