When I searched for Ashtabula to check out what was left of the NYC/LS&MS ore docks, Google Maps offered the following as the "signature" photo for the town.
This looked similar to a Strauss heel-trunnion bascule bridge design, but there were enough differences that I suspected it was designed by someone else and the differences avoided patent infringement. Sure enough, Bridge Hunter indicates the "Patent Engineer/Design" is Thomas Ellis Brown. And Historic Bridges indicates it is one of the few surviving Brown type bascule bridges left in the country, and the only one in Ohio.
(Update: The 1911 Bridge Hunter page for the Duwamish River Bridge was my source concerning Strauss' earlier design.) The railroad bridge may have been owned by a terminal railroad that allowed NYC, NKP and Pennsy to access the ore docks. The bridge is an early Strauss heel-trunnion design. And, unlike other early designs I have seen, this 1911 bridge has not been converted to Strauss' later design. This early design has the machinery room on top of the movable span and the operating strut is fixed to the counterweight tower. By 1919, Strauss had moved the machinery room to the counterweight tower and fixed the operating strut to the movable span. Below is a closeup of the two bridges on the South Branch of the Chicago River that have the modern design. I highlighted the operating strut of the near bridge, which is closed, in red and the strut of the far bridge, which is open, in yellow. You can see that the strut comes out the back of the tower as the bridge is raised. That photo allows you to compare the modern design with the earlier design still used in this bridge.

In this earlier design, the strut moves into the span. And you can see the machinery house on top of the movable span.

( Bridge Hunter , 3D Satellite ) I don't normally do yet another steel tied-arch bridge, but when you get a view as unique as this, I went for it. This is "reverse railfan." Specifically, it is a photo from a train instead of a train. And at the bottom is some photos of the cantilever truss that it replaced. William A.

Big Tunnel: ( Bridge Hunter , indianarrtunnels ) Big Tunnel: Satellite plus Paint Originally built in 1857 for the Ohio & Mississippi Railroad and since controlled by the B & O, it is now a part of CSX. It was shortened and brick lined in 1898. A 1700 foot companion tunnel known as "Little Tunnel" was 'daylighted' (turned into a cut) in 1899. [Bridge Hunter] It was dug for a 6-foot gauge railroad. [ IndianaRRtunnels ] Two of the several photos posted by Carlton Crasher. Jacob Leukhardt Should be one train a day Mon-Fri. The J783 local. I believe it runs between Mitchel and somewhere east of North Vernon. I believe it only runs one direction a day so for example, if it goes westbound to Mitchel on Monday, it should go east on Tuesday, then back west Wednesday and so on. Dennis DeBruler Thanks for contributing photos to Bridge Hunter and for taking photos of B&O's CPL signals . One advantage of CSX not liking this B&O route is that they don'...
I've noticed that NYC and Los Angeles have to pay a lot for water supply whereas Chicago has to pay a lot for water removal. I knew NYC dammed rivers in the mountains that are north of the city and then used tunnels (aqueducts) to transport the water into the city. What I did not know, until I studied the Cannonsville Dam , is that they also get water from the Delaware River watershed, which is a lot further away. Since I found this overview map, I'm writing this post to record it. Project Description , page 6 from nyc.gov A NY Times article about a leak in the Cannonsville Dam focuses on the people aspect of the dam. If you look at the map, Deposit, NY is downstream of the Cannonsville Dam. The residents are still bitter that 1000 people, including entire towns, were displaced over a half-century ago when the dam was built. Now they are bitter that they have to worry about the risk of living downstream of a dam. Since a big river flows right through them, they question why N...
