Western Railroad Discussion > Interesting track layoutDate: 01/20/22 10:58 Interesting track layout Author: SlideSellerII Found this on the giggles while spying on the old DOT Pueblo facility. Anyone know what it could be used for?
Date: 01/20/22 11:17 Re: Interesting track layout Author: DLM It appears to be our governments version of a reverse loop.
Date: 01/20/22 11:41 Re: Interesting track layout Author: PHall Endless runaway track?
Date: 01/20/22 11:53 Re: Interesting track layout Author: KM-ML4000 It is called the "Screech Loop" and I believe is largely used for transit/subway type vehicles.

150-foot radius, so not sharp enough to be a test for streetcars, and too sharp for passenger cars. Date: 01/20/22 12:20 Re: Interesting track layout Author: BN6339 Interesting area to satellite railfan. What is going on here?

It is very possible that is what is going on in the picture.

Date: 01/20/22 19:10 Re: Interesting track layout Author: upkpfan I agree with Typhoon. There is a smaler one SW of Salina, KS. upkpfan
Date: 01/21/22 03:49 Re: Interesting track layout Author: dcfbalcoS1 You cannot 'reverse' on that loop, such as turning power. You can do testing for sharp curves OR pull in with equipment behind you, and then get on the other end of it and pull out. DOubtful anyone would have equipment short enough to make it worth while. Try flange and rail wear tests instead.

But within the realm of modern heavy rail transit and light rail systems. There is a freight rail example of this track arrangement at a grain loadout in Polo IL on BNSF's Aurora Sub: https://www.google.com/maps/@41.997557,-89.5929449,1595m/data=!3m1!1e3 As I understand, trains loaded here are destined for points east or south. I don't get out that way much anymore but I have seen two trains on this loop. One was a 2x1 DPU so I assume the crew swapped ends to depart and the other train had 2 locomotives but fit entirely on the loop so it would appear they moved the locomotives from one end to the train to the other.
