The Sam Houston Zephyr was one of two regional streamliners offering express passenger service between Dallas and Houston, the other being the Southern Pacific's Sunbeam. It originally operated with one of the shovel-nose articulated trainsets built for the Twin Zephyrs of 1935. That original trainset was destroyed by fire in 1944 while Rock Island (which jointly owned the Fort Worth-Houston line and switched off  its management every five years) was in charge of the line, whereupon Rock Island and Burlington introduced "new" (or, at least, new to this route) equipment to cover the duties of the Sam Houston Zephyr and to supplant the former Texas Rocket with the new Twin Star Rocket (see that page for more details).
