Fitting of the truck parts: bolster, axles and side frames; all seems to be good; the wheels turn smoothly.
And now, second step: first level of the suspension; funny to put together! irritation not allowed!!
After attempt, I will have to insert a 2 mm sheet of styrene between the floor and the truck pivot to heighten the car, otherwise the trucks can't move around or a very few; result: I will have to pull down the couplers of the same high!
