All it takes is a little money. No, let me rephrase that. All it takes is a LOT of money, and maybe another one or two hundred additional volunteers. We do the best we can with the resources we've got. We are a lot better off than most museums, yet there is never enough money and enough manpower. In fact, I think we have done one heck of a job over the last few years improving all aspects of the museum. if you want us to do more, come out and volunteer.
And remember, a goodly chunk of what is at the museum is Georgetown Loop Railroad equipment, over which the museum has little or no responsibility, and no resources to maintain. For now it is a mutually beneficial relationship to have the GLR equipment on the museum grounds. Additional track would require lots of additional resources and volunteer hours and would result in more wear and tear on old, fragile equipment. Additional land is always on everybody's mind; if or when it will happen remains an open question. Write us a BIG check, and maybe we could erect a car shed (or course, then we would be flooded with complaints that the equipment is too hard to see and to photograph). What tomorrow will bring is anybody's guess.
The D&IM interurban has undergone restoration by the Rocky Mountgain Railroad Club, which has owned the car since 1950; check them out at:

IIRC, the Birney was also privately owned; I don't know its current disposition.
I have no knowledge of any Denver Tramway street cars. If they were at the museum, that was a long time before my time at the CRRM. Maybe if Dirk Ramsey is following this thread, he can tell you.
