Collectible On Bernina

Hi

There 1 collectible of each kind on the Bernina that are located inside a hangar at the station in roughly the middle of the run, I can see the collectible through the windows of the hangar, however I can not find how to get inside the hanger to get the collectible, and they are the only one missing from completing the task

 

Great. Couldn't name the station or make a screenshot, could you?

 

solution can be found here

There is also a hat under the circular viaduct near Brusio, that can't be reached because of the invisible wall.

 

THank you for the help :-D
