& Pacific Texas Type Locomotives The Texas & Pacific Railroad received the very first purposely designed 2-10-4 built in North America. These locomotives were delivered in 1925 as part of an order for ten Class I-1 locomotives built by the Lima Locomotive Works. The first locomotive, road number 600 and the nine others (road numbers 601 through 609) had 29" dia x 30" stroke cylinders, 63.5 dia. drivers, a 250 psi boiler pressure, a tractive effort of 83,000 lbs and each weighed 448,000 pounds. As was the custom, the first railroad to receive a new wheel arrangement was given the honor of giving it a name and Texas & Pacific selected the name "Texas" for the 2-10-4s. Fifteen more "Texas" type locomotives were delivered from Lima in 1927. These Class I-1a 2-10-4s (road numbers 610 through 624) were duplicates of the first ten except the boiler pressure was raised to 255 psi which increased the tractive effort to 84,600 pounds. In 1928, thirty more were delivered: fifteen Class I-1b (road numbers 625 through 639) and fifteen Class I-1c (road numbers 640 through 654). All thirty were built by Lima and were very similar to the 1927 group except the weight of each was 452,000 pounds. A final 15 Class I-1d (road numbers 655 through 669) "Texas" type locomotives arrived in 1929 to complete T&P's roster of 70. These last locomotives, built by Lima, were very close copies of the previous class except each weighed 457,000 pounds. The only surviving T&P "Texas Type" locomotive, number 610 is owned by the Texas State Railroad and is on Static display in Palestine, TX. Number 610 was restored to operating condition and it pulled the American Freedom Train throughout the southwest during the 1976 bicentennial celebration.
