Trying out the new DeWitt Clinton mech. It runs pretty much the same as the last generation, but it's world's better than the 1st gen. mech. which is of course the worst performing, and the most common (9 time out of 10, the one you find on ebay). Designing a basic wood tender body for it.

I used to be really interested in pre-Wright claims to heavier than air powered flight. But the more I looked into it, the more everybody's stories fall apart. It also makes one appreciate just how thoroughly the Wrights the documented their process, in comparison to other claimants.

Youtube recommended a video to me, and the guy used AI for research. The AI told him that something happened that didn't happen, he repeated it in his video, then used an AI generated image in the video to show it happened, and now the comments are filled with people who're mad that it happened.

Design and building process. Started with dimensions of the 1850 Norris locomotive Copiapo, added missing details (stack and cab) from other historic sources, adjusted proportions to fit the Mantua chassis, printed, fitted together, painted, and now good to go.

Why is it called a "cowcatcher" if it is designed to push cows aside rather than catch them? A good question, with an interesting answer. Here are two illustrations, and an article from 1835 (containing the first known use of the term "cow catcher" that I know of) which make the etymology apparent.

Side elevation and plan view of Isaac Dripps' cowcatcher as first used on the Camden and Amboy Railroad.The illustration shows a grate like structure supported by a frame mounted on a pair of wheels.Engraving of a train from 1852 showing a 2-2-0 locomotive fitted with an early cowcatcher, which is in essence a grate like stucture suspended from the front of the locomotive frame, just above the tops of the rails.The earliest published mention of a "cow-catcher" that I have found, dates to 1835. "...when in the farther part of Mansfield, they run into a drove of cattle, and soon found that their cow-catcher, which they have wisely placed on their night engine, had gathered together two of the herd, and was proceeding with them at a rapid rate, without any damage to the cars, or the knowledge of the passengers, till the engineer saw his new freight, and stopped to discharge. The cow catcher is a lattice work platform constructed in front of the locomotive, so as to take up it any animal with which it may come in contact."

Photo in my collection of the Sainte Catherine tunnel on the Paris-Rouen line of the Ouest railway. The tunnel was built in the 1840s, unfortunately the castle style tunnel mouth was destroyed by a landslide shortly after WWII. Today it features a plain concrete construction.

Another great old pic. Millholland 4-4-0, with Wootten mods. Anthracite burning firebox sticks right out the back of the cab. Reportedly the steamboat lumps of anthracite burned so slowly the fireman might have as many as 40 minutes to waste between shovelfulls.

An article about Professor Eliphalet Nott's anthracite burning steamboat, the Novelty, which ran experimentally in the 1830s. The environmental angle of this article is absolutely fascinating. Forests and timber are so useful, that just burning wood as fuel is inexcusable. Sound familiar?

1830's article about Nott's anthracite burning steamboat. It reads in part "...we need only point to the destruction of our forests--where is our wood to come from if each of our immense boats consumes 30 to 40 cords per day? We have not been in the habit of considering out forests as other than inexhaustible, but such is the state of things no longer..."
