Eastern Railroad Discussion > Where is it & are there more such RR diamonds in the US?

This set of diamonds is likely a pretty well known if not busy location with up to 8 road freights plus a handful of local movements each day.
I'm interested to know what other diamonds on bridges exist and are in use by freight RRs today in North America (ie, transit systems and throat trackage for major passenger terminals shouldn't be considered). Is this bridge unique? Thanks.

CPBD Binghamton NY, RT 11 (Court St Overpass)?...That's the only diamond crossing I've ever seen on a bridge.

Here's anothber: https://goo.gl/maps/LGXGghwymoHmokVv7

TAW

Another one

Pretty neat stuff! I never would have dreamed about doing that on a model railroad.

TAW's location is the Crow's Nest. This is somewhat more unique in that it is open deck, or at least used to be when I took this photo

What RR is this and where? Thx.

Soo Line (single track, now CN) crossing the C&NW (now UP/Metra)

Deval tower, DesPlaines IL

Typhoon's example is Mayfair Tower, Chicago.

TAW

There is one in Dalhart, TX on the Golden State route (UP) crossing BNSF. This would have been a high tonnage diamond due to coal routed to Tx a decade ago for BNSF and UP on trackage rights.

The 12 diamonds of Tower A2 at Western Avenue in Chicago are all atop a bridge, but it's a wide, filled bridge so it's not nearly as visual as some of these smaller examples.

Better than mere diamonds; they're puzzle switches.

Some diamonds, but not all, by my reckoning - although it appears the diamond-only ones have moveable-point frogs.

Deval IL in July of 81.

"Viaduct" ... and yes, technically a diamond over a bridge.

At A-2 all the "crossings" have moveble point frogs.
Metra Milwaukee Dist. MT 3 also has double slip switches where it crosses
the C&NW tracks.

At Kensington in Chicago, I believe there are one or two diamonds above the Kensington Avenue
underpass just south of the tower.  CSS&SB mains crossing the IC Thoroughfare tracks.
This was an excellent idea for a thread and great reader responses too.

 

How can one not miss the busiest railroad intersection in the world?  Lake & Wells in downtown Chicago!

"... in use by freight RRs today in North America (ie, transit systems and throat trackage for major passenger terminals shouldn't be considered)."

That would eliminate the "L" and other passenger only systems.

As for 115th St / Kensington (NICTD South Shore connection to Metra and CN for freight:

The viaducts throw me off due to the volume of dirt between the tracks and the underlying bridge. There are viaducts where each track or track pair has it's own bridge with zero or minimal ballast on the bridge. I didn't start the "find a freight diamond on a bridge" challenge but the viaducts seem to be more technicalities.

Very interesting information! Thanks to all for contributing!
