"The Crash at Crater Canyon (part 1)" is a thrilling two-part episode of the 1950s / 60s TV series Woody's Roundup.
About this creation
In this episode, Jessie the yodeling cow-girl is knocked out by Prospector Stinky Pete, as she had discovered Pete's plans for Woody and the town he protects via the mine tunnels under the town filled with dynamite and nitroglycerin, set to blow up high noon the next day to destroy the town in a giant sinkhole.
Jessie is then placed unconscious on a steam loco which is uncoupled from it's train and sent hurtling uncontrollably through the wilderness to Crater Canyon, where it will meet the Cannonball passenger train on the bridge. (Thus destroying the only fast way to town and keeping Jessie out of the way for the town to explode with Woody saving Jessie and not in town to stop Pete's plan.)
Naturally, Woody rides out on his horse (Bullseye) to save Jessie,who has at this point woken up and discovered the throttle lever missing and steam loco's brakes disconnected. This episode ends with this scene above: Jessie reaching for Bullseye and Woody while both trains are barreling towards each other and certain destruction, while the timer on the clock in town square ticks ever closer to noon.
What happens in the next episode will never be known, as the show was pulled from the airways as the film office where the future episodes and unfinished scripts were kept burned to the ground, destroying all the un-aired episodes. It is assumed, though, that Woody rescues Jessie, stops the town from exploding, and jails Pete all before the credits roll.
The real scene takes place on my Eads bridge with engines 2 and 3, plus the passenger train for the latter 3. The yellow steamer is not even finished: the side not shown is missing one wheel and moving piston and was carefully staged to hide this fact!
