One of the worst movies ever to make to the bottom half of a double bill. Extremely low-budget, and it shows. Lame script (loosely based on Stagecoach), acting varying from firmly stereotypical to "what am I doing here" painful, narrative consisting of a string of set pieces with little attempt to tie them to the story line, in which the train has to "get through", and there's a plot to steal a whack of gold.
Most of the action is shot on a single set, the interior of a passenger coach. Almost all external shots are either rear projection or stock footage, chosen with scant regard for authenticity and still less for continuity. I watched this mess because it has a railroad setting. The train includes a mid 20th century baggage car on a supposedly mid- to late 19th century run to Tombstone. There's a lot of shooting, with dramatic falling off screen when wounded, etc. One of the characters is shot in the left shoulder, and receives a bandage around his middle.
That may stand as the level of writing and editing of this waste of celluloid. Well, maybe not a total waste. It could be used in a film studies course as an example of how not do it. Recommended as just such an example, if you're in the mood for it.
