Arriva has ordered 54 CNG Solaris Urbino 18 buses. The public transport company won the public tender for operating selected bus lines in the capital of Poland. The tender was issued in 2018 by the municipal transport company ZTM Warszawa. It will be the première of Solaris gas buses in Warsaw.

Already 1500 Solaris buses are operating in Warsaw, but this is the first order for CNG buses. All vehicles have to be delivered this year. The articulated Urbino 18 CNG will feature a range of green solutions ensuring a reduction of pollutant emissions. The CNG will be stored in roof-mounted tanks boasting a total volume of 1700 litres. Constituting a mixture of light hydrocarbons, the CNG will be adapted for the use in a combustion engine; the commissioned models will feature 8.9 l Cummins engines with a power of 293 kW, meeting the highly restrictive Euro 6 emission standard.

There will be 39 seats onboard each bus. Solaris will equip the vehicles with a comprehensive set of electronic systems, including voice announcement, constant surveillance of the bus interior and exterior, a passenger counting system and emergency communication for the driver. Passengers will be able to purchase tickets in ticket vending machines. The noise emission of the gas-fuelled Solaris buses will be lower than that of diesel models, which, in combination with an air conditioning system covering the whole vehicle, will significantly increase travel comfort.

CNG buses are the most common alternative drive types in use in Poland. According to the authors of the report of the Polish Congress of Alternative Fuels, replacing part of the diesel bus fleet with CNG fuelled vehicles can contribute to the reduction of nitrogen oxides (NOx) by up to 50%, and of carbon dioxide by up to 20%. Solaris has been producing CNG buses since 2004. So far, over 1100 CNG buses were produced in the factory near Poznań, having been dispatched to such countries as Norway, Sweden, Slovenia, the Czech Republic and France.
