Operation of trolleybuses equipped with batteries contributes to lowering of climate.
The City of Brașov is one of the largest cities in Romania and public transport is one of the levers to provide sustainable mobility for its citizens and surrounding areas. In 2015 the Municipality has approved a sustainable urban mobility plan that addresses the following challenge in public transport sector: improving the quality, security, integrity and accessibility of public transport services, covering the infrastructure, rolling stock and services. To answer to this challenge the Municipality has identified a solution in upgrading and expanding the existing trolleybus system.
26 new trolleybus vehicles have been contracted with a financial support from EU non- reimbursable funds provided by Regional Operational Program 2014-2020, in a joint procurement coordinated by the Ministry. The vehicles have replaced an older trolleybus fleet.
The trolleybuses are 18-metre long to provide high capacity transport. An aerial wire network provides the main power traction. The vehicles are equipped with power traction batteries to provide an wire-free autonomy of 5 km. The batteries are recharged during service operation from trolleybus grid and provide a support to extend the services ahead of infrastructure expansion, with carbon free traction system.
The main stakeholders are the Municipality of Brasov, the Metropolitan Transport Authority of Brasov. Main beneficiaries of the practice are the citizens of Brasov area who benefit from carbon-free public transport system.
- Purchase of trolleybus services: 740.000 EUR / vehicle
- Purchase of public transport management system: 2.74 Mil. EUR
- Personnel responsible for operating the trolleybuses: 3.5 drivers / vehicle
- Personnel responsible for fleet management: 15 persons
Evidence of success
So far, the newly purchased trolleybuses have performed approx. 970,000 km and by replacing the old diesel buses they produced a reduction of pollutant emissions of apox. 4800 kg CO, 11428 kg NOx, 1508 kg Hydrocarbons and 229 kg Particles. Similarly, the resulting reduction in the amount of CO2 is 1828 kg.
Setting up the partnership for the joint procurement process requires mutual understanding from all partners and moving to autonomous battery-based trolleybuses requires technical expertise in this area.
Potential for learning or transfer
This good practice has a great potential for transfer to other entities, as it is a simple and successful system which public, semi-public or private organizations can adapt to their daily habits. The ambition of the system can vary form a small and pilot project to a great electric motorbikes fleet system, depending of specific conditions.
The trolleybus system is a viable road transport solution for routes with a very long predictability, allowing a good balance of investment and operational risks between infrastructure and vehicles.
