Similar to the Moffat Tunnel, Tennessee Pass Tunnel has a curtain! You are looking at it here, rolled up outside the east portal. However, the purpose of the curtain is quite different from that of the Moffat. Whereas the curtain at the Moffat is designed to help vent the tunnel of exhaust, the curtain at Tennessee Pass is used to keep snow and ice out of the tunnel during the winter.

I'm flabbergasted that the curtains have been left open. I would have thought they'd be closed and virtually welded shut to keep people out of the tunnel.
