trolley:motion presentation on the Circularity Compass, a cradle-to-grave framework applying circular-economy principles (avoid-extend-transform-enable) across public transport’s vehicles, infrastructure, energy and governance, noting electrification alone cannot address embedded emissions.

CE4CE project presentation by LVB applying circular-economy principles to public-transport infrastructure, focusing on predictive-maintenance methods to extend asset life and enable early fault detection across the network.

LibroDuct presentation on automated re-wiring technology for trolleybuses, solving unsafe manual reconnection after funnel failures and improving driver appeal and the trolleybus image.

Trolleymotion 2024 presentation comparing drive technologies (depot charging, opportunity charging, trolleybus, hydrogen) via a mountain-tour analogy, arguing the trolleybus offers the highest efficiency and hydrogen is poorly suited to mobility.

Mobility ADO presentation on Mexico City Metrobus Line 3’s e-BRT with 60 Yutong electric buses achieving 40% regeneration and large energy and maintenance savings versus diesel, while highlighting TCO and business-model challenges.

eBRT2030 EU project presentation aiming to create a new generation of fully electric, automated and connected European Bus Rapid Transit systems, targeting cost-per-km and emissions reductions across six-plus demonstration sites.

Verkehrsbetriebe Biel presentation on developing a smart trolleybus system, targeting 100% trolleybus operation by 2030 with only 2.5 km of additional overhead lines, using battery modelling and dynamic charging.

ELL presentation on modern trolleybus operation solutions including battery substations for energy storage, a driver pantograph-assistant system and eBRT wayside and vehicle equipment.

Presentation on planning a hybrid trolleybus (battery/overhead-line: BOB) system for Marburg lines 7 and 27, evaluating catenary-coverage options of 35-68% with biarticulated buses on challenging topography, with approval expected in December 2024.

ebusplan presentation arguing EU rules (Clean Vehicles Directive, Fit for 55, EU ETS) make full bus-fleet electrification inevitable and analysing how much conventional service can be electrified with IMC trolley hybrids on existing overhead lines.
