Golden Dragon electric minibuses using pantograph charging have been introduced on trial routes in Kowloon Tong, advancing Hong Kong’s transport decarbonisation efforts.

Nine Golden Dragon Kast models have commenced service, utilising overhead fast-charging technology designed to reduce emissions and address the limitations of range in electric public transport.

Traditionally, Hong Kong’s 6,000 diesel-powered minibuses have faced challenges transitioning to electric propulsion, particularly due to concerns over range and refuelling time.

The new Golden Dragon vehicles are fitted with 128 kWh fast-charging batteries and use pantograph charging. The system supports a theoretical charging power of up to 500 kW. In practice, this allows a 5-minute top-up to deliver around 30 kilometres of range, while a full charge can be completed in approximately 40 minutes. This enables operators to recharge during scheduled breaks without significantly disrupting service schedules.

Since the first two pilot vehicles entered service on 14 February 2025, they have completed several months of operations in live traffic, including navigating hilly terrain and dense urban roads. Operators report consistent performance in terms of charging reliability and battery range.

The Golden Dragon Kast models introduced in Hong Kong were developed with local conditions in mind. Their dimensions match those of existing minibuses, allowing continued access to narrow streets and constrained terminal spaces.

Safety features include seatbelt reminders, tyre pressure monitoring, a 360-degree camera system, and electronic parking brakes. The vehicles also include dual charging capabilities: in addition to pantograph charging, they are compatible with standard plug-in charging stations, offering greater flexibility in energy replenishment.

The electric powertrain is designed to maintain performance on Hong Kong’s sloped road networks while delivering a quieter ride in dense commercial areas.

This pilot initiative forms part of Hong Kong’s broader ‘Green Minibus Transformation Plan,’ which aims to phase out diesel minibuses by 2035. The programme supports the city’s climate action targets, including significant reductions in carbon emissions from the transport sector.

If the trial proves successful, pantograph charging could become a core part of Hong Kong’s low-emission urban transport strategy.
