  Picture above: The Sm6 Pendolino unit 01 is rounding the curve in the Kerava junction. The unit has just arrived from the high speed track and is emerging to the main line on it's route to Helsinki depot in Ilmala. Although the trains look externally at the first look very similar to the VR-Yhtyma Sm3 Pendolinos, there are significant technical differences. Picture by Stanislav Voronin.

  Picture below: The motor car for the Allegro Pendolino is being lowered from the ship in the Vuosaari harbor. The new generation Pendolinos are built to withstand extremely snowy conditions and coldness associated with dampness. This means the Pendolinos went through as 1 year of testing before the revenue traffic started in December 2010, just ahead of the heavy travelling season for the Russians around the new year.

Karelian trains class Sm6 number 03 in Pasila, Helsinki, Finland


Karelian Trains owned four Allegro Pendolino units replaced in December 2010 the trains "Sibelius" (owned by VR-Yhtyma) and "Repin" (owned by the RzD) between St Petersburg, Russia and Helsinki, Finland. First few years were time for big successes, trains working relatively well and passenger numbers skyrocketing. This lasted until Russian forces invaded Crimean peninsula, part of independent Ukraine, in 2014. Movement started a decline, that has not stopped yet by 2015, effect multiplied with the decline of oil prices. However, unlike many other trains between Russian and Western Europe, these four units are still running 4 daily return trips between Helsinki, Finland and St Petersburg, Russia. Decline might give Karelian Trains a chance to try out other destinations in Finland and St Petersburg, Russsia, most likely end station being Tampere, Finland.

Each Allegro Pendolino multiple unit consists of seven tilting cars, out of which four at the ends are powered. There are first and second class compartments on the EMU. One end of the train also has a little playing erea with a slide for kids, as is custom for VR-Yhtymä modern trains. The middle coach has among others accommodations for the border control offices, something totally new between the two countries. Border control can be made in the mowing train. Although Allegro Pendolinos look just like 400 series Pendolino, they have much in common with the newer 600 series.

Rebuilt track, new high speed rolling stock and other arrangement have cut the travel times dramatically. But until Russian and Western realtions will normalize, there will be no bigger boom using these trains.

4 Allegro unit are currently maintained by manufacturer Alstom and VR-Yhtyma, which is also responsible for the maintenance 18 other Pendolino units in use in Finland. Alstom also shares some maintenance duties.

Using the Allegro lead in early years to dramatic 30% - 50% yearly increase in numbers of travellers between Russian and Finland, so the service can be seen as a great success. Also the trains are working extremely well for a Pendolino design (being of the newer breed of it), so the manufacturer Alstom has quite clearly made progress on technical issues.

  Class Sm5 Flirt1 Commuter Train of JK* (*Pääkaupunkiseudun Junakalusto Oy)
Junakalusto Sm5's 01 and 02 meet at Pasila, Helsinki, Finland
  Picture Above: The Swiss Stadler built Flirt trains stop at Pasila station, the busiest station in Finland. Flirt trains arrived to Finland in 2009, and by 2015 all ordered 41 units will be operational. For the first time in Finland the owner for the local trains is not solely VR-Yhtyma, but the cities around Metropolitan Helsinki and VR-Yhtyma, forming a train owner company Junakalusto. Picture by Stanislav Voronin.

Junakalusto Sm5 number 01 in Leppavaara, Espoo, Finland
The Sm5 Flirt (Fast Light Innovative Rail Transportation) trains are arriving to Helsinki metropolitan area commuting. First 40 units out of 41 ordered have been spotted so far. The type replaces the much aged, exhausted and technically obsolete type Sm1.

Flirt trains bring more modern low floored capacity to the Helsinki local transit. This kind of easy access travelling has been a norm for a decade in other forms of transportation, but rarely on railways. Many Sm4 units which are also partly low floored were also used earlier for the local traffic, although Sm4 was built for regional traffic, where it was much needed too.

The great winter operating capability of the 4 module Flirt train was proved after the two years extensive trials. Junakalusto, the owner of the trains, was convinced about the train type at late 2011 and ordered 9 more for 7,2 million euros each.

  Sm4 of VR-Yhtyma, "Rabbit" "Pupu", Regional Traffic EMU

VR-Yhtyma Sm4 number 6328/6428 in Mantsala Finland
  Above: An Sm4 unit 6328/6428 is seen on the way from Helsinki to Lahti near Mäntsälä. This regional train still beats the cars on its route on the motorway right next to the track, even though 160 km/h (100 mph) might seem a bit slow for the high speed track. Picture by John McKey.

  Below you can make a comparison between the 4 module Flirt class Sm5 and class Sm4 Rabbit with it two modules. Picture by Stanislav Voronin.
VR-Yhtyma Sm4 and Sm5 Flirt pose for sizing at Kerava, Finland

The Sm4 for VR-Yhtyma arrived to Finnish network in 1998 - 2005. The train is very comfortable and quiet for the passengers and features partly low floor, something totally new for Finland at the time. On summers heat the air conditioning works well and keeps the train dry in the winter. Each train has two very well designed roomy bathrooms, that are accessible with a wheel chair too. The trains' technology is located to the roof to keep it dry in the demanding northern conditions. The Sm4 "Rabbit" sports interesting double doors with a round window, which also serve as an easy spotting feature.

Top speed of 160 km/h (100 mph) makes the train well suitable for the regional traffic, but since the rolling stock situation around Helsinki area was earlier quite desperate, especially in the winters, the Sm4 sometimes often arrived to save the day for the commuters. Now the Sm5 (Flirt) trains have most of the time released the Sm4 "rabbits" to their intended regional use.

Rabiits main grazing grounds are on the main line from Helsinki to Riihimäki and beyond to Tampere. Units are also run on the Z-route from Helsinki to Kerava and Lahti.

Most rabbits have by now been painted and vinyled sallad green during their regular maintenance at VR-Yhtyma. The type has been running trials also for some more rural regional traffic, but the benches facing each other were not favored by many passengers and trains were withdrawn to back to help traffic around bigger cities.

The VR-Yhtyma green Sm4 number 6319 in southern Finland


  Sm4 number 6319/6419 was the first unit to be painted new salad green VR livery. Here seen on the main track serving as a H train between Riihimäki and Helsinki.

The whole Sm4 fleet is slowly receiving the new VR faded green livery with animal figures. This will make them look uniform to the long distance fleet of the operator. By mid 2012 half of the fleet has received the green paint.

A green Pendolino nose at Turku service facilities before the train was unveiled, Turku, Finland

The Sm3 Pendolino of VR-Yhtyma started the new era of high speed train travel in Finland. With scarce resources for building the high speed track, the tilting train solution has proved success economically and in some aspects of the system also technically. Finland also has much younger and more developed class Sm6 Allegro Pendolinos on its networks for International traffic.

There were initially strong doubts about the tilting Pendolino Sm3 operations in the harsh winter climate, but the operator has been able to solve many of the problems. The current main problems are that of the trains have more common than normal tendency to catch under floor fires (usually no danger to customers), the under floor compartments flooding with snow and ice in case of motor malfunction and braking cardan axles causing much havoc under the trains. You add the fact that due to the manufacturer initially saving money on electronics all the pulling wheels on half train sets have to be of exact same size, these all add cost to the train operation. No wonder the Swiss SBB has expressed they wish to retire their very similar fleet of similar Pendolinos earliest possible in 2014. If the VR trains could be modernized to same level as the Sm6 Allegro Pendolinos, all these problems would be solved.

In 2011 it was announced, that the class Sm3 will receive ice melting tubes to their bogies to speed up thawing while at depot. Also the couples casing at the ends will be improved chancing the looks of the trains. Hope the units will receive some of the other upgrades too to extend their life cycle from the current.

Sm1 and Sm2 dorming

The Sm2 "Sami" second generation local EMUs for the Helsinki local traffic sported the aluminum body for better durability and added enhanced air support to bogies for comfortable travelling. Otherwise the units are very similar with the class Sm1. The Sm2 and Sm1 units can also be mixed and matched to run in multiple. The type runs lightly and behaves well on rails except for occasional sideways rocking because of the bogie solution. Most commuters around find these trains comfortable to travel, but poorly accessible.

Today all units are finally painted to red-white-gray scheme instead of the old reddish look. In 1980's it was believed that the electric multiple units were harder to spot than their diesel or steam cousins and painting everything yellow at least at the ends would cause fewer run overs. 1990's finally brought the rugged fences around urban railroad lines that finally solved the issue once and for all. And the EMUs could again be painted to what ever the most fashionable color for the moment at VR might be.

All the units were refurbished between 2002 - 2011 despite their obsolete design, meaning they are still unsuitable for effective and comfortable traffic according to the local standards in the Helsinki area today. Imagine elderly, young children and hard walking citizens climbing aboard these high floored trains!

The Sm1 local EMUs have been the backbone of Helsinki commuter traffic since the early 1970s when they replaced Dm7 diesel rail cars plus steam and diesel engine hauled wood sided local trains. At its heyday the 50 unit "Sami 1" fleet provided the commuters for the time great and reliable way to get to work and back home. Progress in EMU technology happened though and the trains have also aged severely. The handicaps in the early 2000s were already obvious: more failures on the way, high floor making it difficult of impossible to transport bikes, luggage, wheel chairs, baby carts, older passengers, etc. Year 2010 the unit 6008/6208 was the first to retire and more rusty, windows broken and fixed with stickers units are following it one by one, replaced by the air conditioned and modern fleet of the Sm5 Flirt trains.

The Sm1 will probably be the only part of the VR rolling stock not ultimately receiving any of the salad green livery.

Easy recognition guide

  • Red-white-gray VR livery, all units
  • striped sides
  • distinctive ends, almost all units have broken windows at the ends. NON curved windows at ends.
  • electric motors whine loudly when accelerating (you can hear at the other end when a person is making a call while in Sm1 or Sm2)
  • Unit 6038/6238 has dark rounded area at the ends so while it is unique, it can also be mistaken with the quite similar looking Sm2 units from the distance.
