When you travel so far / make so much progress doing something but you don't realize you forgot something utmost necessary, until way later on when it's too late. Named after the episode "Thomas' Train" from Thomas the Tank Engine & Friends, where the titular character did not realize he was not coupled to the train he thought he was pulling.
Actor: *finishing his stunt for a film* Hey Jeff! Did you see me drive all the way down San Francisco's hills in a school bus, and crash the oil tanker trailer all in one POV take on my GoPro? You've gotta see the end result! I wanna see it too!
Assistant director: Uh, Bill, you left a little too fast. I think now's a bad time to tell you we forgot to put the SD card in your GoPro. Looks like a bad example of Thomas' Train Syndrome. You just blew our budget now that we lost both of our only trucks.

When I saw six people entering the restaurant and going towards their table I didn't see one woman; it was a sausage train.

When you are walking barefooted in a public place that should require shoes with some busted ass feet.
Wedding reception requires shoes.

When you and your homies run a train on a freaky girl after every single guy in the gangbang took a Blue Chew.

The concieved notion that you can accomplish anything, simply because it is required of you in that moment. Even if you have no background of doing this or there's been no setup for you being able to do this in the past.
Basically a lousy way to explain away a Deus Ex Machina.

As seen on the Flash:
The Flash somehow manages to get a train to vibrate at the same speed he is, so that the train goes through some rubble in the road.
Later:
Kid Flash: "How did you do that?"
Flash: "Because I had to."
Me, watching the show: That's some Flash train-logic right there!"
