Solaris building bi-articulated 24-metre trolleybus
In the course of over 20 years Solaris Bus & Coach S.A. has accustomed clients to regularly expanding its offer, as it kept adding more innovative vehicles to the vehicle range. In 2006 Solaris was the first European producer to launch serial production of hybrid buses, whereas since 2011 its offer includes electric buses. The latest project of Solaris’ Office of Research and Development (BBiR) is a bi-articulated trolleybus of 24 metres.

After the recent unveiling of an innovative trolleybus equipped with hydrogen fuel cells as range extenders, made for Riga operator Rigas Satiksme, the development department of Solaris Bus & Coach is now working on a completely new addition to the company’s offer - a bi-articulated, three-unit trolleybus measuring over 24 metres.

The idea behind the prototype vehicle - the new Solaris Trollino 24 - is to create a platform for the future, serial production of 24-metre hybrid or electric drive vehicles and trolleybuses. The end of the production of the bi-articulated trolleybus is scheduled for mid-2018. Next they will be delivered for test drives to selected European cities and during those rides the vehicle attached to a trolleybus overhead line will undergo further type-approval tests before it can be released for passenger traffic.

The latest Solaris product will be highly advanced in technical terms. The driveline will consist of two traction motors propelling two drive axles. A pack of 94 Ah (58 kWh) batteries installed in the bus will be recharged during the drive, collecting current from the overhead line via a bipolar pantograph traditionally applied in trolleybuses. What is more, the energy accumulated in the batteries will be used to fuel the trolleybus whenever it detaches from the electric traction. In order to ease manoeuvres in urban traffic, the fourth axle of the vehicle will be a steering axle. Apart from featuring a unique door layout of 2-2-2-2-2, the vehicle will also be fitted with an electric power steering (EPS) pump.
