Traintop Battle

A staple of Westerns, but still seen in plenty of action films and series, the Traintop Battle is Exactly What It Says On the Tin. Often the result of an aborted Train Escape.

A train has plenty of advantages for an action scene: it's fairly enclosed, without people able to go too far either way for fear of falling off, it has plenty of opportunity for tunnels and overhead lines for your Look Behind You moments, it doesn't need much explanation, the high speed acts as wind to let characters billow dramatically. In short, it turns an Action Movie into a Fighting Game. There's really no other way to justify Boss Arena Idiocy, and it's pretty much ensured that somebody's going to suffer that most dramatic of defeats; a short drop followed by a sudden stop.

If hero and villain are trying to get to a location in time, it means the hero can be thrown off, and "lose" without dying. Or a villain may be forced out of the action, only to return later.

It's also close enough to "normal" people to show the look on their faces as the ceiling collapses, or when someone breaks in through the windows.

A similar effect can be achieved by riding on a truck. Subway trains rarely have the room on top for a good battle, but are still seen occasionally.

The Standard Snippet for a Traintop Battle is Suppe's "Poet and Peasant Overture".

May feature the Cool Train, but doesn't have to. May be the result of a Train Job and could in theory be apt for a Thriller On the Express but in practise they prefer to keep to the tense atmosphere.

A subtrope of Interesting Situation Duel. If the battle happens atop a moving gondola rather than a train, then it's a Cable Car Action Sequence.

Anime & Manga
"Joey: So you dueled this guy on top of a moving plane?

 * And then topped by Kaiba (oddly enough) when he and a filler villain from the same arc battle on top of a private jet. Even Lampshaded for its ridiculousness.

Kaiba: Maybe I did. Don't you geeks have someone else to annoy?"

"Ein: Thanks!

 * A recent episode of the Best Wishes arc of the Pokémon anime had Meowth pretend to reform and join the main characters, saying that Team Rocket fired him for messing up one of their evil plans, but it is then revealed that he joined them as part of a trap set up inside one of Team Rocket's trains, and that Meowth was never fired at all.

 * Live and Let Die...
 * Licence to Kill, however, has the battle on top of trucks.
 * One of the earliest examples in Buster Keaton's The General.

 * Silver Streak
 * Wild Wild West

 * To elaborate, Just as awesome as it sounds.
 * The Sherlock Holmes tribute novel The Seven-Percent Solution features a train-top Sword Fight between Holmes and the villain.
 * The Warhammer 40000: Eisenhorn trilogy features a traintop sword-fight between Eisenhorn and the mercenary captain Clansire Etrik. However, the train is not moving at the time, which is probably a good thing since it is noted as being able to make a trans-continental crossing in a day.
 * It is, however, coated with ice and in the middle of a blizzard, so that may even things out.
 * In The Other Side of Dawn, Ellie jumps onto a goods train from a bridge and ends up fighting an enemy soldier atop the train and inside one of the carriages.

 * The second Christmas Episode of Community has one. Did we mention it was stop-motion animated?

Tabletop Games

Video Games

 * The videogame adaptation of Quantum of Solace includes a flashback level set during the unremarkable train ride to the eponymous Casino Royale. It now includes a traintop gunfight.
 * Final Fantasy VI has several fights upon an Afterlife Express, though little is made of the particular environment. The boss is the train itself.
 * Paper Mario the Thousand Year Door, against the Giant Space Flea From Nowhere Smorgs. To simply reach the boss fight itself, you also have to hammer your way through a veritable horde of them on top of the Excess Express first.
 * The Mole Train boss fight in Donkey Kong Country Returns.
 * Ratchet and Clank Going Commando had a fight atop a hover train with jumps from car to car. The first game featured a short train top battle, as well.

 * Just after the first chapter in Dark Cloud 2, you have to throw bombs at a car with two mooks in it firing a machine gun at the train. Fail and the game ends from the train derailing.
 * Sonic the Hedgehog seems to like this trope. In Sonic Heroes there is an entire act with a railway system. Mostly you just "grind" down the rails, but a tunnel area has you doing exactly this trope, fighting off minor enemies on the train that try to push you off.
 * Sonic Triple Trouble's Sunset Park Act 3 takes place on a train, with the boss apparently being the engine.
 * Sonic Shuffle has the Riot Train board.
 * The video game Ur Example is probably the first stage of Hudson Soft's Stop The Express. The second stage goes inside the train.

 * Zero 4's intro stage took place on fast-moving trucks.
 * Mega Man X 5 had Grizzly Slash/Crescent Grizzly's stage, which was technically centered around trucks, but it's the same idea.
 * Slash Beast in X4. His entire stage was composed of several trains, barring a small section between the areas, when the first one crashes.
 * Of course, Charge Man in Mega Man 5 beat them all to the punch, and even resembles a steam locomotive himself for added fun.
 * This is reaching Once an Episode status for the series. The first real boss battle of Mega Man ZX Advent starts out on top of a train car, then falls inside it as the boss slowly demolishes the roof.
 * Don't forget Megaman Legends where Mega has to fight two out of three of the Goldfish Poop Gangs on top of one train while shooting across at another train outfitted with bombs, turret guns, lasers, and missiles.
 * Yet another game with a train-battle level: Bubsy. Though that one's probably forgettable.

 * The Last Express, which is set entirely on board a train, could hardly escape a scene like this.
 * Sunset Riders, essentially a side-scrolling Wild West shoot-em-up, has the requisite moving train level. Depending on the version, it can either take place on top of the train where you shoot both at enemies coming in from the sides as well as the ones poking up from the windows below and where not jumping over the quickly-approaching girders in time means instant smashy death or riding alongside of one, where you need to jump over logs dropped from a wagon so your horse doesn't trip over them and cause you to die in a similliar way.
 * Skies of Arcadia has a train battle level, both inside and out. Eventually, Vyse and co. are tracked down by Implacable Man Galcian, and have to head toward the front of the train while he chases after them...very...slowly.
 * Vandal Hearts also has a train battle level. The villains start releasing the back cars (very slowly) after a while, so any of your characters that are lagging behind may find themselves ejected from the battle prematurely.
 * Contra: Shattered Soldier has a level that involves chasing a train down on motorcycles, attacking the weaponized caboose, and heading to the engine. At which point a mecha attacks the train, leaving the player to wonder why our One Hit Point Wonder heroes had to bother.
 * Before that was 'Contra: Hard Corps. The boss was a Humongous Mecha that pushes the train to a halt and climbs onto it, which was the inspiration for the boss in Shattered Soldier''
 * Hard Corps Uprising likewise has one taking place on an underground railway, with another set of tracks running along the ceiling as well and cars being destroyed left and right either by having either track end prematurely, taking too much damage from enemy fire, or being used as projectiles by yet another Humongous Mecha running along the tracks. And that's before you get to the actual boss, which takes place in a vertical tunnel with both trains now moving straight up and subject to be destroyed entirely by the boss's huge laser. Thankfully there's a neverending supply of train cars, which proceed to roll in from offscreen and attach themself to any of the remaining ones whenever one is destroyed.
 * The entire final act of Gears of War takes place on a train, with the members of Delta Squad fighting their way to the front car to activate a superweapon.

 * The Star Wars Expanded Universe apparently has trainlike vehicles that allow for this, just going really fast.
 * One mission of Jedi Academy centers around this.
 * A sequence in Shadows of the Empire uses the trope.
 * In Wario Land: Super Mario Land 3, there are two levels in Parsley Woods taking place in/on a train. Falling onto the rails while the train is in motion is instant death.
 * There are also levels like this in The Shake Dimension, Wreck Train and Derailed Express. You've got both fighting across the top of the train and making your way through the carriages though.
 * The 1800s level of Teenage Mutant Ninja Turtles Turtles in Time was set on a moving train of flatbeds. Other than Foot Soldiers riding up on horses and boarding, it could have been a ground level and not changed the essence of the gameplay.
 * In an inversion of The Problem With Licensed Games, The Tiny Toons game for the NES (The one with the Amusement park setting)) has Hampton Pig on top of a Train Ride, having to fight several enemies, avoid getting stranded on disengaged cars, and fight Arnold the Pit Bull.
 * The SNES game also has a battle taking place on a train, except it's Buster Bunny doing the fighting in this case. It even uses the above-mentioned Standard Snippet as background music in one part.
 * Banjo-Tooie has a fight in the train's boiler. Old King Coal (a Grubby Boiler Monarch who's not the jolly old soul Kazooie thought he was) won't let you use his train until after you beat him into submission.
 * Time Splitters: Future Perfect in the Bond parody level. The second part is on a train. After you apply the emergency brakes, the camera PoV cuts between the train and your partner's girlfriend, making it look like she's about to be run over. As the train grinds to a halt, the camera pans out...
 * In Ninja Gaiden II for the NES, Ryu is in a hurry to get to the Lahja mountains. His solution: climb onto the top of a train and fend off the enemies that attack him as he makes his way to the locomotive.
 * At least two of the Metal Slug games have fights on moving trains, including trains as bosses or subbosses.
 * Armored Core for Answer features a fusion of this and the Battleship Raid trope with the Arms Fort Great Wall, GA America's ultimate AF. Your objective is to get inside it and blow it sky-high. I don't think anyone's been dumb enough to attack it's outside other than to get into the damn thing.
 * The second stage of Time Crisis 2 has this where you fight along not one but two speeding trains (the first the the passenger compartment and the second alongside an adjacent train). After fighting off the mooks you deal with the boss who takes you on with a gun turret, swings a missile around at you (no, really) and lastly tries to take you down with a rail gun while holding onto a helicopter before you blow him up. Likewise in TC3, the end of the second area has you fighting atop a speeding train. The difference here is at the end of the stage, the bridge is blow out from underneath, resulting in the heroes being forced to climb their way up from the still attached dangling compartments.
 * The N64 Spider-Man game features a level where Spidey has to hold off hordes of lizard men while atop a subway car.
 * Tomb Raider IV has one of these. With ninjas.
 * An obscure action-adventure game for the first Playstation, Covert Ops: Nuclear Dawn (known also as Chase the Express), has one of these due to taking place onboard a high-speed train. You have to shoot a boss, jump over to his train, pull some switches and jump back to your train.
 * One of the stages in Blaz Blue has the fighters standing atop a speeding monorail.
 * The Sega shooter Confidential Mission 2nd stage is set on a train which not surprisingly forces the heroes on top of the train in few occasions
 * Luis of Grand Theft Auto IV the Ballad of Gay Tony jumps aboard an El Train in order to steal one of the cars. He has to shoot his way past half of the LCPD to reach the front.
 * Uncharted 2: Among Thieves has the best Traintop Battle yet seen; starting at the caboose, Nathan Drake works his way to the front one car at a time, alternating between gunfights and crawling along the sides of the cars while dodging passing signal lights -- and then a helicopter gunship shows up and starts blowing cars off the train behind him!
 * Not an exaggeration. This is the level developers should look to for thrilling train sequences.
 * The Legend of Zelda Spirit Tracks features a train-top battle as part of the final boss fight.
 * Shadow Hearts opens up with one of these.
 * The SNES adaptation of Batman Returns has one.
 * In Famous has a mission where Cole has to rescue a bunch of hostages on a train. Unusually, Cole himself provides the train's motion, powering it with his electrokinesis to move it somewhere safe while zapping enemies from the top.
 * This happens in The Saboteur, in which Sean has to rescue a defecting scientist from a Nazi train before the train reaches the bridge that Sean has rigged to blow. There are also hijackable turrets every couple of cars that can be fired at any Nazi installations the train happens to pass.
 * The final mission of Total Overdose is along the top of an old steam locomotive.
 * Old Dynamix game Heart Of China has a battle atop the Orient Express. He's armed with a sword. You're armed with a piece of metal you ripped off the train. Don't forget to duck when the tunnels show up (the only way you know to duck is that he ducks first; he's facing the direction the train is moving).
 * The third map of Blood took place on a Cabal-owned train, which ends up crashing into a carnival when Caleb blows up the engine.
 * Both Unreal Tournament and Unreal Tournament 2004 have Assault maps with this sort of premise, though the 2004 map isn't so much "trains" as "gigantic trucks". Falling off is possible, and leads to instant death.
 * Every other level of Data East's Express Raider is a train top Beat Em Up.
 * The fourth stage of Super Double Dragon is a truck-top battle, which may be a Shout Out to the second level of Bad Dudes.
 * Two back-to-back levels of Syphon Filter 2 have you racing to the front of a train to stop it before it reaches a blown-out bridge. You fail to stop it, but jump onto a chopper stolen by Lian just before it falls through.

Web Original

 * The Ballad of Cripple Kane starts out with of course, a saloon brawl, a horse chase, but it ends up on a train. Oh wait you knew that, reading the trope and all. It's still 'awesome'!
