in 1919, a member of the 3800 class of 2-10-2s fitted with a four wheel trailing truck. Nearly 100 more 3800 class locomotives were delivered after 3829, all with the 2-10-2 wheel arrangement. 3829 was used by the Santa Fe as an experimental locomotive. Photographs exist that show 3829 fitted with at least two different four wheel trailing truck designs through the years. No additional members of the 3800 class have been documented with four wheel trailing trucks and 3829 was scrapped in 1955 with a four wheel trailing truck.
, and this time it was an expansion of the 2-8-4 "Berkshire" type that Lima had pioneered. The four-wheel trailing truck allowed a much larger firebox and thus a greater ability to generate heat (and thus steam) - the Superpower design, as Lima's marketing department called it, meant for a locomotive that could develop great power at speed and not run out of steam-generating ability. A version of the Berkshire with ten driving wheels instead of eight was an obvious development, and the first delivered were to the Texas and Pacific Railway
, after which the type was named.
high-drivered Berkshire type to produce 40 of the T-1, a Texas with 69 inches (175.3 cm) drivers that was both powerful and fast, fast enough for the new higher-speed freight services the railroads were introducing. All subsequent Texas types were of this higher-drivered sort.
(PRR) ordered few new locomotives after 1930; electrification
both ate up the railroad's resources and provided a supply of excess steam locomotives, soaking up any requirement for new power. It was not until World War II
had begun that the PRR's locomotive fleet began to look inadequate. The Pennsylvania Railroad urgently needed new, modern freight power. The War Production Board
prohibited working on a new design, and in any case there was not enough time to trial a prototype. Instead, the PRR cast around for other railroads' designs it might modify for PRR use, settling on the C&O T-1. Some modifications were made for the PRR; the PRR drop-coupler, sheet steel pilot
, a PRR style cab
, a large PRR tender, a Keystone
numberplate up front, and other modifications. It still betrayed its foreign heritage by lacking the PRR trademark Belpaire firebox
and by having a booster engine
on the trailing truck. 125 locomotives were built between 1942 and 1944, the largest fleet of Texas type locomotives in existence. All were sold for scrap as the Pennsylvania Railroad dieselized.
, nicknamed "Madam Queen". This locomotive was similar to the C&O T-1 described above, with the same 69 in (1.8 m) drivers but 300 psi boiler pressure and 60% limited cutoff. It proved the viability of the type on the Santa Fe, but the Great Depression
shelved plans to acquire more.
In 1938, with the railroad's fortunes improving, the Santa Fe did acquire ten locomotives; these came with 74 in (1.9 m) drivers and 310 psi (2.1 MPa) boiler pressure, making the Santa Fe 2-10-4s the fastest and most modern of all. Of the original order of ten, five were oil-burning and five coal-burning; when the Santa Fe ordered 25 more for 1944 delivery, all were delivered equipped to burn oil. The first of the 1944 batch produced 5600 drawbar horsepower on road test, the highest figure known for a two-cylinder steam locomotive.

steam locomotive with a Texas wheel arrangement in service, designed as a mixed traffic locomotive suitable for light rail. It was designed by A.G. Watson, Chief Mechanical Engineer of the SAR from 1929 to 1936, and built by the North British Locomotive Company
in Glasgow. Only the one locomotive was built, at the time representing the maximum power obtainable on Cape gauge
from a ten-coupled non-articulated locomotive that was limited to a 15 long tons (15.2 t) axle load on 60 lb/yd rail. To enable it to negotiate tight curves, the third and fourth sets of driving wheels were flangeless.
The tender was an unusual experimental type using six pairs of wheels in a 2-8-2
wheel arrangement, with the leading and trailing wheels in bissel type pony trucks and the rest of the axles mounted with a rigid wheelbase. The tender’s wheel arrangement did not prove to be very successful and, with the exception of a similar tender built in the Salt River shops in Cape Town for test purposes, was not used again.

The early Lima Texas types were low-drivered, 60 through 64 inches (152 through 163 cm) in diameter, which did not give enough space to fully counterweight the extremely heavy and sturdy side rods and main rods required for such a powerful locomotive's piston thrusts.
