Gunsmoke (1955) : 17x14

The conclusion to this three parter. Dillon kills the guard that was gunning for him and the passengers take the train back over. The only problem, all the fuel has been destroyed so they have to get more fast. Festus and Newly are still out with the gold leading the men from the train on foot. Dillon's legs are numb and Doc has no choice but to operate whether he cripples him or not. Leaving the gold shipment and taking the mules, Newly and Festus head back to the train to try to get it going. Sinclair has the men push the wagon back to the train and gets there in time to keep it from taking off. Beth tells Sinclair about Matt Dillon, but Dillon's faster than a gun even lying down and ends up killing him. The train takes off leaving the bad guys and all their gold sitting at the tracks with no way to get anywhere.
