when i went skiing at winter park last year, i took the wonderful oppertunity to take pictures of the west portal of the Moffat tunnel, and there are several things i am curious about. <br />1. there is what looks like a small radio antenna with wires leading into the tunnel, am i correct in assuming that it is a repeater for trains in the tunnel? <br />2. as i moved closer to the tunnel, i heard the distinct sound of an air hose bleeding off air, but it was steady, and did not let off, and was still there the next day. What is this? <br />3. i have heard rumors of a "door" closing off the east portal except when a train is passing. if this is true, what is it for, how does it work, and how is it activated when a train nears it? <br />thanks in advance for any information.
