The Sm6 Allegro is a high-speed train which runs between Helsinki, Finland and St. Petersburg, Russia. The service started on 12 December 2010.[2][3] On board the inaugural service were Finnish president Tarja Halonen and Russian prime minister Vladimir Putin.[4]

Overview

The Sm6 appears similar to VR's earlier Sm3 Pendolino series, but is based on the fourth generation[5] 'Pendolino Nuovo' or 'New Pendolino' designs and its construction differs from the Sm3 in many ways.[1]

Unlike the Sm3, which has a Fiat-designed hydraulic tilting mechanism, the Sm6 is equipped with Alstom's newer tilting bogies with pneumatic operation. The top speed of the train in passenger traffic is 220 km/h (140 mph) and the train can run at a speed of at least 200 km/h (120 mph) between Tikkurila and Luumäki and Vyborg and Saint-Petersburg after extensive rail works[5]. The aim is to reduce travel time between Helsinki and Saint Petersburg from 5½ hours to three hours.[6] The travel time in 2011 is 3:36.[7]

The trains are owned by Karelian Trains, a 50–50 joint venture between VR Group (Finnish Railways) and Russian Railways (RZhD).[2]

The Sm6 is equipped to operate on both the Finnish and Russian standard railways. The units have a dual electric system for using both the Finnish 25 kV, 50 Hz alternating current and the Russian 3 kV direct current. The wheelsets are built to run at over 200 km/h (120 mph) speeds on both the Finnish 1,524-millimetre (5 ft 0 in) and the slightly narrower Russian 1,520-millimetre (4 ft 11.8 in) gauge, and the doors are equipped with a retractable step to make boarding from both Finnish 550 mm (22 in) high and Russian 1,100 mm (43 in) high platforms easy. The units are equipped for both the Finnish and Russian railway technical systems, which differ substantially.[8]

Sm6 stands for electric multiple unit (Finnish: sähkömoottorijuna, literally 'electric motor train') model 6. The name Allegro is the musical term for quick tempo.
