Texas and Pacific 610, also known as "Will Rogers", is the only surviving example of the Texas and Pacific Railway's (T&P) class I-1AR 2-10-4 "Texas" type steam locomotives. Built by the Lima Locomotive Works in June 1927, No. 610 and its class were based on Lima's prototype "Super Power" 2-8-4 design, and the T&P rostered them to pull fast and heavy freight trains.

No. 610 last ran for the T&P in 1949, before it was retired, the following year. It was then put on static display at the Will Rogers Memorial Coliseum in Fort Worth, Texas. In the late 1960s, No. 610 was at risk of being scrapped before the 610 Historical Foundation, led by Dave Pearson, acquired the locomotive. In 1975, work began to restore No. 610 to operating condition, and the following year, it pulled the Texas portion of the American Freedom Train.

From 1977 to 1980, No. 610 was leased by the Southern Railway to pull excursion trains for their steam program. In 1981, No. 610 returned to Fort Worth under its own power. The following year, it moved to a small museum complex for display. In 1986, it was moved again to the Texas State Railroad in Palestine, Texas. As of 2024, No. 610 remains in storage under Texas State Railroad ownership, and it is towed outdoors for display during occasional events.
