Truth to tell, the only thing I had seen directed by Phil Karlson before catching THE TEXAS RANGERS on TV was a 1970s flick entitled WALKING TALL, which was neither good nor bad but somehow stayed in my memory.
As other viewers have pointed out, the great thing about THE TEXAS RANGERS is that famous names bunch together so you almost feel you are watching history unfold. In this case, you have baddies like Sam Bass,John 'Wes' Hardin, the Sundance Kid, Butch Cassidy, and more all planning and riding hard to carry out train robbery that would set the government back quite a lotta dough.
Good old John Carver (played by George Montgomery) plays the fake bandit with sheriff and Pinkerton detectives in the background, assisted by pretty Gale Storm (sounds tempestuous!) and they somehow sink that gang of evil doers. Carver gets shot up in his left arm but is still nimble and strong enough to go around the train and take care of Rudabaugh and other heavies.
Pleasant Western with solid cinematography and competent stunt work, bringing back memories of the 1950s to anyone who lived in those days when the Western began to undergo re- and de-construction, paving the way for spaghetti. 7/10.
