It's very interesting to see what you can find on railroads. Usually, it's expected to find Western-Cullen Hayes equipment on the Union Pacific, but I found something else... US&S. Now, I've been told that UP experimented with different companies, but it's interesting to see the stuff still up and in use.
Some background info:
The Union Pacific line is the Villa Grove Subdivision. It runs all the way to Chicago. The crossing signals with this equipment can be found (so far) from St. Anne, IL to (so far) Grant Park, IL.
Let's start off with something you wouldn't expect to find on a UP crossing... a US&S mechanical bell:Click to Enlarge
A lot of the US&S equipment found on these crossings are just the lights.Click to Enlarge
Now, a lot of crossings have similar light setups... WABCO/US&S lights with UP LEDs. Additionally, that US&S bell was the only one I found out of 10+ crossings. All others either have WCH/GS e-bells, Safetran mechanical, or WCH mechanical.
Let me know if your UP line has any US&S stuff like that. I haven't seen it on the Joliet Subdivision to the west. If you want an example of what's on the Joliet Sub., look here:http://www.rxrsignals.net/Illinois/A-K/ ... od/Center/
