Well, as you say, let's see:
>there's asbestos lagging on steam locomotives,
True but usually not friable, and the degree of friability is the problem.
>asbestos in old brake shoes,
Only in compositions shoes, which aren't all that common in museum equipment. Asbestos was quite common in automotive brake shoes, so you need to separate the effects of rail from those of automotive.
>asbestos insulation on wiring,
Never seen this, not even on traction motor leads.
>PCB's in old electrical transformers,
How many RR museums have old transformers? (Which had to be certified as being non-PCB at least 30 years ago).
>old waste oil,
What kind of waste oil, crankcase drainings?
>lead - based paint,
Only if the paint had white lead (lead acetate) in it, and besides you had to eat the paint or breathe particles of it created by sandblasting to get exposure. Lead primarily causes neurological problems.
>just to name a few possible carcigens you could be exposed to in a museum environment.
By the simple act of not leaving your house, you are exposed to a meteor strike.
White chrysolite asbestos, the kind used in the US, isn't anywhere near as dangerous as the "blue" stuff used in Europe and elsewhere.
