Troubleshooter Jefferson Harder (John Payne) is sent to Laramie by the Army to investigate the sabotage that is preventing the railroad from finishing it's line connecting the East and West. Upon arrival Payne quickly finds out the worst kept secret in town, that old buddy and current town saloon owner Jim Shanessy (Dan Duryea) is behind the chicanery, though nobody is ever able to prove Shanessy and his henchmen (Myron Healey and Lee Van Cleef) are involved. The town leaders, while happy about support from the Army, are disappointed from the start that they have only sent one man to do the job and grow increasingly critical of the heavy-handed tactics employed by Payne to clean up the town.

Rails Into Laramie packs a lot of action into it's 80 minute run time. Between busting bad guys heads Payne barely has time to strike up a romantic relationship with Dance Hall owner and partner of Jim Shanessy, Lou Carter (Mari Blanchard). Very little melodrama to be found in this one as Payne spends most of his time eradicating the town's scofflaws.

This movie follows the Universal International Pictures formula of using off the A-list leading actors with familiar casts, packaged in a medium budget production. A formula that worked very well for them and it works here too. John Payne may be the best leading actor of the post World War II era that few people remember today. A versatile actor Payne looked equally a home whether in the saddle, a crime drama or a comedy. Here he carries the day in this action saddle flick.

Good drive-in grade Western flick.
