Though I'm sure you've seen it NJP, for anyone else curious there's a cool video of some unusual engineering floating around covering the Cascade Tunnel. It's so long that it needs powerful blowers to force air into it to vent the locomotive's exhaust, and to ensure that the air flows through the tunnel, one end has a door that closes to keep the air moving the right direction. Have a look!
