Funny you should mention that. Back in the '80's, when the CZ was routed onto its scenic route across Colorado, there was a Rio Grande trainman I think was named 'Billings', who loved to ham it up on the train P.A. and spin tall tales to 'entertain' the passengers. He would tell about the engineer..."Mad Dog (whatever the last name of the current engineer was), accepting a challenge from some lady kayaker to race along the Colorado River. When passing through the Moffat Tunnel, he would tell of thousands of dollars spent by Amtrak commissioning artists to paint murals inside the tunnel walls. He would then go on to say that unfortunately, the lighting was disabled that day, but that you are encouraged to ask your fellow passenger's to 'borrow their flashlight', to see the great work that Amtrak had created for them.CZ in the Moffat Tunnel, not too scenic.
As you might expect, some folks were delighted, and some were annoyed by his spiel. I believe he was later ordered to refrain.
