Why not add this bridge detail?

[P5se Camelback]

Wayne, Does that bridge say "Made in 1832", I wouldn't walk across that bridge let alone be in a train going across it!

Now wait just a minute ... there are quite a few bridges still in use that are over 173 years old that are still in use! The Frankford Avenue Bridge, also known as the Pennypack Creek Bridge, the Holmesburg Bridge, and the King's Highway Bridge, was uilt in 1697 in the Holmesburg section of Northeast Philadelphia, Pennsylvania, and is the oldest surviving roadway bridge in the United States. If you have ever driven north out of the Frankford section of the city on US Route 13, you have driven across it!

But wait, we didn't even have trains in 1832, my eyes must be failing me

I beg to differ! A quick check on the history of the "John Bull" (to confirm my sometimes failing memory) reveals that it was built by the
Robert Stephenson and Company, a locomotive manufacturing company in the town of Newcastle-upon-Tyne. The company was founded in 1823. It was the first company set up specifically to build railway engines.

What follows is a short (and incomplete) timeline of the locomotive ...
... June 18, 1831: The John Bull is constructed by Stephenson and Company in England.
... July 14, 1831: The John Bull departs Liverpool aboard the ship Allegheny bound for Philadelphia, Pennsylvania.
... September 4, 1831: The John Bull arrives in Philadelphia.
... September 15, 1831: The John Bull makes its first runs in New Jersey under its own power.
... November 12, 1831: Robert Stevens hosts a group of New Jersey politicians on a series of trial runs pulled by the John Bull.

So, you see, we DID, in fact, not only have trains in 1832, we had steam trains in 1832! Actually, many of the earlier "railways" had wooden rails and were known as "gravity railroads," as they were powered by Sir Isaac's dicovery. One of the earliest of those was the Mauch Chunk Railroad, built between Summit Hill and Mauch Chunk, Pennsylvania in 1827. (Mauch Chunk is now Jim Thorpe and home to an operating tourist steam train pulled by a (blue) Pacific.) The line was built as a gravity railway to haul anthracite coal from the mines down the mountainside to the Lehigh River and was the first railroad of this type.
