Eighteen-meter long fully low-floor articulated trolleybuses.

The Pilsen company Škoda Electric together with another Czech company SOR Libchavy have manufactured eighteen-meter long fully low-floor articulated trolleybusdesigned for public transport. The modern Škoda vehicle facilitates transport of passengers due to five doors for boarding and exiting. The first trolleybus Škoda 31 Tr was made in the end of 2010 and it is the latest Škoda trolleybus.  Škoda Electric supplies all electric equipment and carries out the overall assembly of this three-axle vehicle. The electric equipment is stored in a container on the roof of the vehicle. If the trolleybus is also equipped with an auxiliary diesel generator, it is possible to drive the vehicle even in places lacking trolley wires. The asynchronous traction engine and microprocessor-controlled voltage inverter with possibility of recuperation significantly reduce energy consumption and maintenance costs for the vehicle operation.

The comfort of passengers is improved by the overall low-floor design of the vehicle and by wider aisles between the seats. Boarding and exiting of passengers is made easier by means of the so-called kneeling, when the trolleybus tilts to the edge of the pavement. An efficient system of heating and a well-arranged information system improve the comfort of passengers as well. There is also a tilting platform for wheelchair users. The trolleybuses Škoda 31 Tr are operated both in the Czech Republic in Hradec Králové and Brno and in Slovakia in Prešov, Žilina and in the Slovak capital Bratislava.
