The Milwaukee F7s are accepted as the fastest steam locomotives by a different measure—scheduled speed between stations. In 1939, shortly after they were introduced into passenger service, the Twin Cities Hiawatha schedule was modified such that the engines would need to run the 78.3 mi (126.0 km) between Portage and Sparta, Wisconsin in 58 ...
Railroads also implement their own limits and enforce speed limits. Speed restrictions are based on a number of factors including curvature, signaling, track condition, and the presence of grade crossings. Like road speed limits in the United States, speed limits for tracks and trains are measured in miles per hour (mph).

The highest posted speed limit in the country is 85 mph (137 km/h) and can be found only on Texas State Highway 130, a toll road that bypasses the Austin metropolitan area for long-distance traffic. The highest speed limit for undivided roads is 75 mph (121 km/h) in Texas. Undivided road speed limits vary greatly by state.
The Pennsylvania Railroad's class H6, H6a, and H6b steam locomotives were of the 2-8-0 "Consolidation" freight type, the most numerous class on the railroad with 1,707 units and the second most prolific 2-8-0 class in North America, with the USATC S160 class rostering 88 units more.
No in-house tests were made with a dynomometer, but estimates from the Altoona test rated 6110's drawbar pull at 4,100 horsepower at 100 mph. [16] No prior class of steam locomotives in numbers could develop over 4,000 drawbar horsepower at this speed, while the only class which could match this figure was the later New York Central Niagaras.
These were the only 0-10-2 locomotives ever built in the United States and this purchase gave the name "Union" to this type. [ 1 ] The Union Railroad was a switching and transfer line owned by U.S. Steel , serving a number of plants in the area and connecting with six trunk line railroads.
