An evil executive or tycoon has big plans for something, typically a railroad or a highway. Suddenly though, in the middle of construction, something goes wrong. Quicksand is found, a town is in the way, or something else goes wrong. Whatever it is, now all of a sudden, there is a town, city, tree, memorial, planet, grumpy old man, or whatever in the way of the completion of a project, and this means either stopping/delaying the project (which means wasting a lot of cash) or destroying the town.
This is known as a "Railroad Plot" due to it being frequent in Westerns, but other examples are not uncommon, including in real-life.
No connection to Railroading, though a plot that requires the GM to force things along may well be called one.
- The plot of Blazing Saddles gets started when the corrupt Hedley Lamarr learns that his planned railway course has to be detoured because of some quicksand, and conspires with an easily-bribed governor to hire a gang of baddies to rough up the remote town of Rock Ridge so that they can get the land on the cheap.
- Belgian/Mongolian film Khadak involves a group of nomadic herders who are told by the government that their livestock have all caught a plague, and will have to be destroyed, thus requiring the herders to settle down in town and go to work. It's a plot to get the herders off the land, which is then turned into an enormous mine.
- Used in the plot of Mr. Smith Goes to Washington. Smith wants to turn a tract of land into a not-Boy Scout camp. The same land is bought by a corrupt businessman planning on grafting it to the government to build a hydroelectric dam proposed by his paid-off Senator. A battle of wills ensues.
- In Once Upon a Time in the West, McBain knew that any train line through the region could only refuel water for the steam engine in a single place and build his farm on the site, expecting to make a small fortune by selling water to the train company. So Morton had the family killed by Frank so that he could buy the land himself.
- In Who Framed Roger Rabbit, Judge Doom intends to wipe out Toontown with a gigantic Dip-spraying machine so a new freeway can go through its former location.
- Wild River: A rare example of a work in which the person/entity building the "railroad" is sympathetic and well-intentioned. The Tennessee Valley Authority will do a world of good for Appalachia, bringing jobs and electricity, and stopping the regular deadly, catastrophic floods of the river, saving lives and property. Chuck Glover, the TVA man, doesn't want to hurt anybody. Still, though, Ella Garth and her island stand in the way of the dam the TVA needs to build.
- Avatar: Humans go to Pandora to mine unobtanium. The largest deposit is, unfortunately, under the Na'vi Hometree.
- In The Ghost and the Darkness, the obstacle obstructing the railroad is a pair of man-eating lions who are decimating the construction crew.
- Made In Mongolia: Bodi's a country bumpkin who just inherited a house and a lot in the capital. Hujee is a Corrupt Corporate Executive who wants to build an apartment complex there, and by hook or by crook, he's going to get Bodi's plot of land.
- At the beginning of The Hitchhiker's Guide to the Galaxy, the Vogons blow up the earth because it's where a "hyperspatial express route" is to be built. An unusual case as this doesn't make up the bulk of the plot; it merely kicks off the book's events... At least until a couple of books later, when it turns out that rather a lot more is going on than the reader or the characters had previously been aware of.
- In Daredevil (2015), Wilson Fisk's master plan is to raze down Hell's Kitchen and replace it with his own building plans.
- A highway version in the "Aunt Bee, the Crusader" episode of The Andy Griffith Show, with veteran actor Charles Lane as Mr. Frisby, a chicken farmer whose property is about to be seized by Sheriff Andy, who ruthlessly insists that Mr. Frisby must vacate the property because his is the only one where the new bridge can be built. Aunt Bee and the townswomen appear to start sticking up for him by protest rallies, only to turn against Mr. Frisby when moonshine stills and drunken chickens are discovered in his cellar.
- In an episode of Little House on the Prairie, the railroad was coming to town and bringing with it drunks and other rowdies that would completely transform the character of Walnut Grove. The town fought against the railroad and the railroad redirected to go to a different small town.
- The Grand Finale involved a railway baron deciding to do the above-mentioned situation again... and managing to buy the lands where Walnut Grove is located right out from under its inhabitants. The inhabitants of Walnut Grove decide to give the best show of defiance that they can... by blowing up the whole town and leaving the baron with no community to profit from.
- In Cranford, the imminent arrival of the railway is a major source of concern and disagreement in the community, with many concerned that it will destroy their way of life.
- In Up, Carl's house is in a block where a major development is planned, and when he kept stubbornly refusing to sell it, the developers attempted to get him committed to a senior home. They did succeed in evicting him and clearing the lot, but not quite they way they expected.
- Is the focus of a two-part Regular Show episode. The railroad leads to Hell, reviving several antagonists.
- A railroad is being built in the Bugs Bunny cartoon "The Unruly Hare." Bugs has some fun at the expense of railroad surveyor Elmer Fudd.
- The controversial concept of Eminent Domain embodies this trope. For example, Kelo v. City of New London established the very scary precedent that it's legal for the government to use eminent domain to force people to sell their properties to land developers, as long as the government can make a case that the proposed development would significantly enrich the community. In at least one case, this has resulted in a company demolishing a block of historic houses, then changing its mind and not actually building anything there.
- Regarding the Kelo decision, it might be well to note that it was particularly controversial because the land was being confiscated to give to another private owner, for commercial development, as opposed to using it to build public works like eminent domain is really used.
- At least there is some good to come out of it: After the precedent was established, a number of states enacted legislation clarifying that eminent domain could only be used to build something with an obvious benefit to the public.
- Pierre Trudeau evicted an entire town on the Gaspé Peninsula, bulldozed and burnt down the houses, in order to turn the land into a nature preserve.
