SpongeBob goes into the Krusty Krab freezer to find that the Krusty Krab has run out of Krabby Patties. He and Mr. Krabs try to make more, but cannot remember the recipe. Krabs gives SpongeBob the key to the vault in which the recipe is hidden, and he and Patrick board a train to the bank for the safety deposit box. Sometime during the ride, the key to the box is stolen and SquarePants and Patrick Star must find the thief. Just then, Plankton walks up and Patrick searches him, but finds him clean. The duo stops the train to find the suspect responsible for stealing the key. A nanny and her baby were searched, only to find a stolen jewel that was stolen by triplets. The next suspect, the butler, was revealed to be a thief named Orin J. Ruffy who stole $75,000 worth of ham sandwiches. SpongeBob cried hopelessly but soon found Patrick having the key; in fact, he found it while he cleaned SpongeBob's shorts. They went back into the train and were on their way to the bank. Eventually, Plankton bats them out of a window and the best friends must chase the train. It is revealed that Plankton has the key. SpongeBob morphs himself into a hang glider and he and Patrick fly back onto the train to pursue him. Once they return, SpongeBob and Patrick chase Plankton. But, Plankton disconnects the cars of the train, leaving SpongeBob and Patrick in the front car. SpongeBob and Patrick try to stop the train but Patrick stupidly breaks the brake (of the train) causing the train to go out of control. He made several weird, futile attempts to stop the train, one of which is to put a heavy object on the tracks. This only caused the train to flip and move forward while some of the wheels were off the track. The two manage to bring all wheels back in place when they stopped in front of a retirement home. Then, Patrick stupidly breaks the throttle, which he thought said "BRAKE". Meanwhile, Plankton was caught trying to steal the formula by Krabs. However, he still escapes with it, but the train comes into the bank and stopps Plankton before he could leave. Plankton's plan failed again, but Krabs had to pay the damage to the bank with his bank account. 75 years later, and elderly SpongeBob finishes the story of the "Great Train Caper". His grandson responds with a cheer in excitement over his video game.
When this episode aired on November 11, 2010, it gained an audience of 6.6 million viewers and the most watched non-sports broadcast on cable for the week of November 14, and second overall only to a Monday Night Football game between the Steelers and the Bengals.

When Plankton uncoupled the tender from the engine, the steam engine still keeps moving. However, by uncoupling the tender, the steam locmotive would come to a complete stop, as it would involve disconnecting the water pipes and vacuum brake pipes between the cab and the tender, preventing water from coming to the boiler. Furthermore, tender engines do not store coal behind them: they store it in the tender.

Why was Mr. Krabs the one who had to pay to fix the bank? When it was actually SpongeBob and Patrick who destroyed it with the train.
When SpongeBob and Patrick were chasing Plankton, they pass Nat Peterson who is asleep on the train. But when they call for help, Nat is at the Emergency station, even though he was supposedly on the train.
When Plankton says "Oh, now there on time!" it may be a reference to "One Coarse Meal" when he was waiting for the bus to hit him.
This is the second time someone says the line "Cops! I need you!" in this episode, it was said by Patrick. The first time was in the episode "Banned in Bikini Bottom" where the line was said by Plankton.
The title is very similar to the episode name "Patty Caper".
The last scene of this episode inspires by the Arthur episode: "The Curse of the Grebes" where Buster who is a grandpa tells his grand-kids the story about the Grebes winning again.
S.C.A.B.S. stands for "Salt Comes After Barnacle Shavings". This is a possible spoof to P.E.M.D.A.S. (Parentheses Exponents Multiplication Division Addition Subtraction).
