Sm3 "Pendo" High Speed EMUs

The Sm3 Pendolinos form the backbone of VR-Yhtyma long distance high speed traffic. 18 units travel lengthy distances daily in Finland, even if the temperatures are well on the freezing side and there is lots of snow. The maintenance of the Sm3 units by the VR-Yhtyma is the best in the world so a working model has been able to form to keep the units challenging technology working, unlike in many other countries in Europe. This of course does not fix the design mistake by the manufacturer Alstom/Fiat, that the trains have a tendency to catch underfloor fires. Every time these happed, the fire brigades in Finland have expressed their grave concern in the main national news media. While similar Pendolinos in Switzerland are retired earliest possible, in Finland the train operator VR-Yhtyma has to rely on the proper maintenance and hope for as few fires as possible.

The future is green, even for Pendolinos. Below the first green unit seen in the new color sceme hiding at Turku service facilities before officially entering the service. Even the salmon is green at the Pendolino restaurant car (for real...)! Picture by John McKey 2010.

The Sm3 Pendolino of VR-Yhtyma started the new era of high speed train tavel in Finland. With scarce resources for building the high speed track, the tilting train solution has proved success economically and in some aspects 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 operations in the harsh winter climate, but the operator has been able to solve many problems. The current main problems are that of the trains have more common than normal tendency to catch underfloor 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 saved 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.

  • The white base with a broad red or soon green stripe and seen inside Finnish territory gives no room for no error.  For curiosity, the salmon on restaurant car is green!
  • The other existing Pendolino has curvy stripes, silver and large blue Allegro  text on it.

Sporting a quickly replaced coupler hatch cover to keep the snow and ice from building in the compartment the unit 02 is seen passing Kerava southwards towards a stop in Tikkurila before it's destination in Helsinki. As with any other high speed train types, Sm3 have also suffered from coupler compartment door problems.
