Is this true? I just checked the timetables at http://www.tagplus.se/
and they do have trains going directly from Stockholm to Umeå
(Stockholm Central - Umeå Central).

Jarmo,
As Myron has already mentioned, you can get to Umeå by train, and that can
include actually arriving at the train station. But the train line is a bit
indirect and, not infrequently, it involves changing to the bus in Sundsval.
At least I think that is true, I have never actually taken the train in
Sweden, and I'm not sure why you would actually want to do this, flights in
summer can be pretty cheap. Then again, I hate travelling by train, so I am
not a good judge.
