Building drawings

[torikoos]

    Here is the Davis station building.
I'm now looking on how to best construct this building. It maybe styrene, although making castings and use hydrocal may work better for the big walls. Balsa wood is another option. I am planning to get the dimensions roughly from the pictures, however if someone knows where to obtain a copy of the real drawings (a scan or so) then that would be great. Do I approach Amtrak for that, or would it be the archives of the town of Davis perhaps? Any ideas?

Cheers,
