Once I read some information about the X2000 (and X2001, then never version,
but runs under the X2000 name).
The engine does not tilt, only the cars. If you look for X2000 on the net
you can find pictures showing the train in curves with an upright engine.
All passenger cars can tilt up to 8 degrees, but will stay upright in case
of any error in the tilt system.
The cylinders are indeed a main part of the tilting system, which could have
been the other way. Some older Finnish cars had a tilting mechanism too, but
it was pure mechanical, where the bogie somehow would lift the outer sideof
the car (the cylinder is connected to the end of the car, not the middle). A
reason for using the middle of the car might be weight reasons, secondly by
adjusting that part they have 50% more tolerance to work with.

Really great model; I have been thinking of building one myself.
