Aside from standard 4-6-0s the design was also built to Camelback
specifications for Northeastern lines like the Lehigh Valley, Jersey
Central, and Erie. Despite newer models superseding the ten-wheeler (the aforementioned Consolidation in freight service
and faster 4-4-2 Atlantic to pull passenger trains) it still found
enormous success, even after being bumped into secondary status on many
lines where it carried on performing various roles. For instance, as
with other small wheel arrangements such as the Mogul, Prairie,
American, and others the 4-6-0 was well liked by shortlines, logging
railroads, and various privately-owned industrial operations due to its
weight and nimble ability to operate on light trackage.
For some this meant operating their ten-wheelers for narrow-gauge service such as the Eastern Tennessee & Western North Carolina (the "Tweetsie"), Oahu Railway & Land Company of Hawaii, White Pass & Yukon Route of Alaska, the Rio Grande's narrow-gauge lines in Colorado and New Mexico, and various others. By the time production of the 4-6-0 had ended an incredible 16,000+ had been built among all of the various setups already mentioned. With so many built the locomotive remained in service many decades after production had ended. For instance, several ten-wheelers remained in service at small logging and short lines well after World War II until sawmills either closed or the locomotives were replaced by diesels.
Today, several 4-6-0s are preserved around the country, including
several of which that are still in operation. Some of the more
well-known operable ten-wheelers include New Hope & Ivyland #1533,
(originally built for the Canadian Northern, later Canadian National, in
1911), Sierra Railroad #3 in California, Alaska Railroad
narrow-gauge #152 (now #2) at the Huckleberrry Railroad in Michigan,
Tweestie narrow-gauge #12 in North Carolina, Virginia & Truckee #25
in Nevada, Nevada Northern #40 at East Ely, Southern Pacific #2248 in
Texas, and finally Texas & Pacific #316 (now #201) also in Texas. There, you can also learn about all of the 4-6-0s currently in some
state of preservation.
