The grasshoppers were their first "production" locomotives, 0-4-0 wheel arangement and very short wheelbase, which was good because the original main had some very sharp curves. The crabs were next, a heavier 0-4-0. These we about all the weight the original stone railroad could tollerate. By the civil war they had 4-4-0 for light passenger service, 4-6-0 for mountain passenger service, and my personal favorites, the muddiggers which were 0-8-0 camelbacks for the coal drags. Muddiggers were good for 9 pot hoppers of coal Eastward from Grafton. See Impossible Challenge about early locos and West End for the muddiggers, although not so called in West End. Go to the B&O museum if you can swing a way to get there. They have all manner of odd, to our modern eyes, equipment.

One said that the first 4-4-0 was built in 1837 based on a 4-2-0. From the various pictures in these books, it looks like the 4-4-0 was very comman and well established by the 1850's.

In 1833! This was the first US locomotive with (1) a pilot axle and (2) a pilot. So that the pilot (which pivoted) and pilot axle could clear the front drivers, they were disconnected from the rods, making the locomotive in reality a 4-2-0. It also got a whistle, bell, enclosed cab, and 8-wheel tender. Quite a pioneer. It ran again in 1980. The company I worked for at the time worked on the project.

That wheel arrangement gave the US railroads both the flexibility and the adhesion that US grades and poor quality track demanded. A single driving axle would not handle the grades and the 0-4-0's that were tried would climb off the rails at the slightest joint kink. An effective single axle pilot was actually a rather late development in the 19th century. dd Reply bobwilcox Member sinceDecember 2001 From: Crozet, VA 1,049 posts Pre Civil War Steam Locomitive Posted by bobwilcox on Wednesday, September 14, 2005 3:22 PM It seems to me there was a lot of expermentation in locomotive design before the Civil War. We came out of the Civil War with the 4-4-0 as the standard American design for the next 30 or 40 years. Does anybody out there have any information about early locomotive development in th US? Things like grasshoppers and camels on the B&O? Bob Reply Join our Community! Our community is FREE to join. To participate you must either login or register for an account.
