A follow up to my other video; "The Flying Scotsman and Mallard won't remain in the spotlight forever" There are a few steam locomotives may have beaten the speed record held by Mallard in the past, but were not properly documented. Some may not have beaten the record, but had good high speed performance nonetheless. A C&O 4-6-4 with Caprotti valve gear, The PRR 4-4-2 7002, UP 844, Milwaukee Road Hiawatha steam passenger engines, and N&W 611.

Some new information has recently surfaced regarding the C&O 4-6-4:

C&O never had Hudsons with Caprotti gear at all, and what they did have with poppet valves dated to the postwar era.
The first poppet valve engines were class L1, Nos. 490-494, which were rebuilt from F19 4-6-2s (which carried the same road numbers) between 1945 and 1947. These engines were streamlined to handle connecting sections of the stillborn Chessie streamliner, and were shrouded except for the 494, which was the first engine to go through the rebuilding in the big shop at Huntington, W.Va. They had Franklin Type A poppet valves. The 490, the second rebuild, survives in the B&O Museum in Baltimore.

The road also had Hudsons 310-314, class L2a, with Franklin Type B poppet valves, built by Baldwin in 1948--the heaviest Hudsons ever built, the last Hudsons built for an American road, possibly the last built anywhere. These were intended to be streamlined, along with the last 4-8-4s (Nos. 610-614, class J3a), but neither class got the shrouds due to cost and weight concerns.

In regard to the Hiawatha steam passenger trains:

In the book, "Railroading from the Head End" by S. Kip Farrington, there is a chapter on the Hiawathas, and a copy of a speed tape taken from one that shows mile after mile at 100 mph. The line had no speed limit at the time; engineers were told to run as fast as needed to make time, consistent with safety. There were some famous signs on the route that warned the engineers to "Reduce to 90" on certain curves, and the level crossing with the EJ&E at Rondout had a speed restriction of 100 mph!

A Popular Mechanics Magazine article about the 6-4-4-6 S-1, allegedly one of the fastest steam locomotives ever!

I do not speak for the T-1 trust, but have donated in the past.
