Oh, Ah. My bad. Please continue your search for a good question!
Here's an amusement while I try thinking of a real question.
Why isn't this installed incorrectly?
Is it part of a counterwight on a trunnion (bascule) drawbridge?
Or you just took the picture or processed it upside down?
Ooops, apologies. Wrong shadows for that!
rcdryeIs it part of a counterweight on a trunnion (bascule) drawbridge?
But you are getting ever so slightly warm...
Where would the fun be in that?
There is a very good reason why what you see is so. And an interesting one...
is it normally under water?
No.
Is it a turntable bridge made out of a bridge, or a bridge made out of a turntable bridge girder?
Exactly so.
The interesting thing about this one is that the original 'flat' side that had the track is facing down, and the belly in the center (which on this one is a fairly pronounced V-shape) faces up.
Which of the two, and who, how, where, and when?
So - a former deck span (ties and rails on the flat side of the girder) turned "belly up" and widened to be a through span turntable bridge.
There were lots of former turntable bridges in use as regular bridges.
The bridge is installed at Frankstown, Pennsylvania, and can readily be searched up on the Web by that location.
It was my naive expectation that most of the converted turntable bridges would be 'right side up' with shoes at the outer ends on abutments, and the deck widened from the flat 'railroad' surface by longer bridge-tie supports, welded brackets, or some other expedient short of separating the webs and inserting a whole new deck structure.
Is the turntable bridge in Frankstown Township? There's also a Frankstown section of Pittsburgh.
Here's a question that ZO would like...
Before 1948 a train carried through sleepers from a major city, passing through four state capitals before handing off some of its through cars. The second, connecting, train went through two more state capitals before reaching its final destination, and handing off the sleepers to another, third, train which passed through four state capitals before the cars' run ended in another major city. The connecting train also received cars from another train from the same origin point that only went through two state capitals on their way to meet the second train.
Postwar upgrades changed the competitive picture, ending the through service, but some form of the connections lasted up to the early 1960s.
Some parts of this question have been asked in a different form. What I'm looking for are the state capitals touched by the third and final train.
Well, not to spoil anyone else's chance for a completer answer, the first train was on the PRR, and the State Capitals were Trenton, NJ; Harrisburg, PA; Coumbus, OH; and Indianapolis, IN, with end-points NYCity & St. Loids. The competitor ran only through Albany, NY and Indianopis, the NY Central.
I'll have to investigate the Katy, Frisco, and Missouri Pacific for the rest of the answer, with my first guess being the MP and then the TP, with Austin Texas and Oklahoma City possible candidates. With a few hours, I should come up with the rest of the answer.
RC, I'm asking you to double-check. You may be in error on one of the state capitals for the third train, which I believe could only be either SP or AT&SF. And I have to check the St Louis Southwestern - Cotton Belt for the seconf train, in addition to the Katy, Frisco, and MP.
The thru sleepers ran first-to[second train, second-third, but your wurstion does not demand first-thru-third.[
Don't restrict yourself to the capitals of U.S. states. So far, so good.
My server is giving me problems in pulling up the Aztec Eagle and attempting to find Mexican State Capitals. Probanly I'll be able to use a friend's computer and email connection this Monday. But with this start, another reader might be able to complete the answer and win the right for the next question.
It's going to be a run-through with the Penn Texas, probably handling the sleeping car arrangement that I recall being MoPac-painted but lettered Pennsylvania. Would have gone via that branch of the Sunshine Special until 1948, but that wouldn't have involved the lightweight car. So Aztec Eagle (en Espanol) is likely it, as Mr. Klepper noted. Someone with an OG can confirm the capital information... and get the credit.
This was inspired by a coupe of quiz questions from ZO a while back. Dave has all of the capitals east of St. Louis on both routes (Indianapolis is in both lists). The through cars predate the Penn Texas, running under the "old" name. Postwar through cars to Mexico originated in San Antonio.
I had a post about this but it disappeared.
The post-1948 PRR run-throughs didn't go further south than San Antonio. I don't know about the pre-'46 Sunshine Special, or what was the '46 to '48 arrangement.
The stops on the Mexican side were Nuevo Laredo (due to the border crossing), Monterrey, San Luis Potosí, and Mexico City
Saltillo and Guanjuato were the other state capitals. Mexico City DF is sort of like Washington DC (Districto Federal).
Dave had the right idea. Through cars off of the Sunshine Special and Southwestern Limited lasted until 1948. Most NYC through service to Texas and points south ended with the postwar Budd-built Southwestern Limited. The Sunshine morphed into the Texas Eagle and later the Penn Texas.
Obermod can have the next question if he wants it.

While the Sunshine Special did become the Texas Eagle, the Penn Texas was strictly a New York-St. Louis train.

Por nada.
The Penn Texas did handle through cars to Texas. I do not recall either the Spirit of Saint Louis, for some time all-Pullman, or the all-coach Jeffersonian handling through cars.
Name a station constructed by a rairoad that was contained within one city, then during successors' ownership served both city-only and intercity trains, and then for a long period served only trains, intercity and suburban (with importance), that operated outside the city, but now is back to almost its original role, the city and possikbly one suburb if my geography is correct, but nothing that can be called intercity.
When used by intercity trains, you could buy food and drinks on some scheduled runs.
There were through cars (PRR) off the Penn Texas that operated as far south as San Antonio. As far as I know, none ran further south than that, either to Laredo or across the border in Mexico.
After the Texas Eagle replaced the Sunshine Special, Mopac connections via Laredo were handled by change of cars at San Antonio. Heavyweights lasted into the 1950s, after which MoPac 10-6s were used. Through cars were operated by Pullman.
