Full Steam Ahead: An Additional 20 Trams with Voith Traction Systems are Destined for the Streets of Helsinki
- Energy efficiency, reduced life cycle costs and increased availability were the key criteria used in order to secure the contract
- The successful operation of the current fleet further assisted in securing this order
- A conventional bogie mechanism is combined with modern low-floor technology
Finnish rail vehicle supplier Transtech Oy, which forms part of the Škoda Transportation Group, commissioned the first of the 40 new low-floor trams in 2013. Delivery of this series is scheduled for completion in 2017. The follow-up contract recently signed, includes the subsequent delivery of another 20 trams featuring complete drive systems from Voith. Each system comprises of high-voltage equipment, two double traction inverters and eight complete drive units, consisting of motor-gear units and complete wheel sets. The Voith scope of supply also includes the monitoring and diagnostics system for the entire vehicle.
The Artic© low-floor tram achieves a 100% low-floor configuration despite a freely pivoting bogie. A separate motor-gear unit with a continuous output of 65 kW drives each of the eight axles of the 27.6 m long vehicle. The traction motors receive their input power via two EmCon double traction inverters with a continuous output of 2 x 220 kVA each.
"The specifications to be met by trams in the Finnish capital are especially stringent due to the challenging weather conditions and the knock-on effects for the transport network," explains Alfred Gmeiner-Ghali, Vice President Sales & Marketing at Voith Digital Solutions Austria. "Alongside maximum driving comfort and minimal running costs, the particular robustness of the vehicle coupled with their reliable traction system were the decisive factors in awarding us the order for our electrical drive systems. We are delighted about this follow-up order and regard it as confirmation of our successful collaboration to date with Transtech Oy and operator HKL in particular."
Ollipella Heikkilä, Head of Rolling Stock at Helsinki City Transport is also impressed: "The high efficient and most reliable Voith traction systems in our new Škoda ForCity Smart Artic trams are an important part to achieve the lowest LCC we ever have experienced in Helsinki."
