Just thought I'd mention we have about 1 meter (about three feet) of snow here, and currently the thermometer shows -28 degrees Celsius (last weekend we had -32 degrees).
Everything else works fine, except the Pendolino trains (locomotives made in Italy), of which one crashed right into the Helsinki Railwaystation a couple days ago. Dunno who the smart one was who decided Italian locomotives is a brilliant idea in this climate... They freeze every winter, usually they just don't move, but this time the brakes of the locomotive had frozen (the brakes on the carriages worked, which was the reason the train didn't crash in at full speed, but a train moving 20 km/h still does make an impact). Good thing the train was mostly empty, just the personell in.
