From Classic Trains found by Googling:
"The widespread application of air brakes in the 1880s spelled the end of the 4-4-0. Air brakes made it possible to run longer and heavier trains, and that in turn created a demand for bigger locomotives. Freights that once could have been handled by 4-4-0s soon needed 2-6-0s and 2-8-0s. Passenger trains were put in the charge of 4-6-0s and 4-4-2s.
"Once heavier power appeared, major railroads consigned the 4-4-0 to light passenger jobs, often on branch lines, although some short lines continued to use it in freight service.
"After 1900 few new 4-4-0s were built, with the very last going to the Chicago & Illinois Midland in 1928. Along with two other Americans received the prior year, the engine was used on a couple of local passenger runs."
"By this time, over 25,000 Americans had been built. The 4-4-0 lasted into the diesel era and some examples ran into the late 1950s."
