I have an O72 switch in a tunnel and it's been trouble free. It's a FasTrack switch and they're pretty reliable. It's also just inside the tunnel entrance so I can still get at it. Deeper in you'd want to make sure you have an access panel. That's one other thing to plan for: if you do tunnels make sure you have access to the entire length. You can usually reach about 12-18" into a tunnel, after that you'll want an access hatch of some manner. Rest assured that a train in a tunnel will always derail 1/4" out of reach!
