On the issue of vibration....
I really dont think this is a big deal unless the trains are 
running under the building! most instruments are reasonaby 
resistant to external vibrations - anyway they have enough 
attached computer fans to be sure they have plenty of 
internal vibration !!!

Actually , the real point is dont let them put your center in 
the basement....its just a borrible place to live - I know - I 
have suffered from other peoples wonderful decisions to put 
flow labs in the basement for 20 years....its usually because 
someone tries to make a big deal of vibration or light or 
something.....and I think its pretty much pointless........I feel 
like a mole now..
