Helsinki Sm5 trains

On-Board System for Helsinki Sm5 trains in Finland
Stadler selected Teleste’s On-Board System for Helsinki Sm5 trains in Finland in 2007. The system is comprised of the following modules: PIS, CCTV, Public Address, LED and TFT displays, phones and intercoms, Ethernet network, rear view, system interfaces and remote management functions.

Stadler, a Swiss rolling stock manufacturer, has been building trains for 75 years. Stadler is headquartered in Bussnang in eastern Switzerland and has a workforce of over 7,600 based in various production, service and engineering locations across Switzerland, Germany, Spain, Poland, Hungary, the Czech Republic, Belarus and the United States.

In 2008, the first two Sm5 trains were delivered to the end customer, Pääkaupunkiseudun Junakalusto Oy, who is also the owner of the fleet. The company is a subsidiary of the cities of Helsinki, Espoo, Vantaa and Kauniainen and the VR Group. The units are leased to the Helsinki Regional Transport Authority (HSL), but VR operates the trains.

Sm5 trains are operating in the metropolitan area of Helsinki. The project is comprised of 32 commuter trains. Currently, after options, the fleet contains altogether 81 trains.

The customer was looking for a modern, integrated and flexible on-board system to support the existing back office systems and to have capability to further develop new functionalities. They also wanted to have an effective maintenance process and streamlined multiple traction operations, for example automated coupling and uncoupling of train units. One of the targets was to improve work efficiency with more automated functionalities such as Driver Only Operations using camera views for door surveillance. Teleste’s On-Board system is one of the first IP-based systems on the market.
