Hi,
Now that strikes me as very interesting. Let me relate to you a story that happened to me some years ago.
This happened in Pomona, CA, on the Southern Pacific tracks, which are now Union Pacific. It was an interchange and a new U-25B had its rear truck on the ground, right after going through the interchange switch, turnout, trying to pick up some empties. The engineman was fairly young and fairly new to the job and really shaking, thinking that he had just lost his job. The conductor and brakeman were sympathetic, but not having a re-railer available could do nothing more than phone in the problem and await the inspector and the truck with the hook to re-rail the new engine. By the way, a U-25B does look ridiculous with one truck on the ground.
I arrived on the trusty old Schwinn, my chase car, heard the engineman's fears and told them I would try to help and look around. I went to the points of the interchange switch an lo and behold they were worn beyond belief. Pieces from the tops were actually missing. I called over the Conductor and told him that when the Inspector arrives to ask him to Condemn the Switch,, as I pointed to the worn points and ran my fingers over them.
I stuck around until the repair crew showed up, and watched them re-rail the U boat, as the Conductor and the Brakeman spoke to the Inspector. The Engineman was a ball of sweat. Finally, the Inspector takes out a special lock and red tag and attaches them to the bad switch. All proceeded well after that and the Engineman left with his crew all smiling.
