Steam truck

A steam truck is a mentioned only vehicle.

Background
A ghoul refugee describes an attack by Super Mutants of Unity on Necropolis, who utilized steam trucks alongside guns and bombs. They described the vehicle as moving "on wheels but without any brahmin."

Appearances
Steam trucks are mentioned in Fallout.

Behind the scenes
The vehicles are mentioned in the Fallout Bible.Fallout Bible p.76: "QUESTIONS GALORE" "1g. How did that guy from New Reno Arms get vault-tec speech module? And how did that friend of Vic ( from vault city ) get the "vault13 flasks" ( I don't remeber that it was explained in FO2 )? Oh, and why Enclave didn't do anything about master after he took vault-tec demonstration vault? BTW. How did master move, he's just a big peace of crap!" ''1. Vault-Tec speech module: He got it from a traveling merchant (similar to how Vic got the V13 water flask). Eldridge likes to collect old Pre-War relics and throw it in his basement to keep Algernon amused - and in the hopes the kid will build a nuclear missile he can use to hold all of New Reno hostage. 2. Ed the Brahmin Dealer may have traded with some of the Vault 13 refugees from Vault 13 when they left the Vault after the Vault Dweller at the end of Fallout 1, or one of the V13 refugees may have traded with a random caravan master that eventually sold it to Ed. Again, it was mostly a plot device carrot, and no documentation exists. 3. The Enclave didn't even exist as an idea in Fallout 1 (to my knowledge), so they never really factored in to any of the events in Fallout 1. 4. I have no idea how the Master was moved. It was probably either by a large (steam) truck or caravan, but I don't have any specific information on how he was moved. I doubt a caravan could do it unless Grey was much smaller and, uh, less "spread out" than he was at the end of Fallout 1, which is entirely possible, but he sounded pretty fucking mutated in his audio diary in the Military Base. Maybe they poured him into in a toxic waste barrel and transported him that way. I haven't found an explanation in F1 anywhere – so if anyone finds one before I post an answer, let me know. Fallout Bible p.77: "QUESTIONS GALORE"'' "6. Last update, you said there were 1/200 cars/people ration in the NCR. If there were so many working cars in NCR, where were they? " ''They’re there. It’s game logic. You don’t see them for the same reason NCR is only three maps, only has 1 councilor/senator, and only about 40-50 people in its city limits. That’s why the Chop Shop in Reno exists, why the bum outside of NCR offers to watch a car for you before you show up in one, and a reason that NCR built a garage in Shady Sands So to explain "game logic" in this instance, there’s nothing precious about building a car of your own if you can steal one – or if somebody else in town has one. Or in the words of one designer (me), “there's no good reason why a PC would want to undertake a fucking huge Fed Ex quest to rebuild one if they can jack one from the locals.” The last part is especially true considering town-wide mass murder is possible in both Fallout 1 and 2. And before you get the image of tanks and jeeps flying around everywhere with heavy machine guns mounted on the back, most of that junk is old tractors and crap like taxis, old buses, snowplows, and even old construction equipment. It's possible that mysterious old steam-truck mentioned in the bowels of the F1 data archive is still lumbering around somewhere. The caravan houses of the Hub, in particular, around the time in Fallout 2, have been looking to further its trade influence, and new vehicles (and types of transport, such as trains, boats, or barges) have been eagerly sought after for carrying large amounts of trade goods vast distances. Good ol' human greed will move mountains. Or at least rebuild things that can. Once they learn of the Enclave's presence in the North, they are likely to have huge bounties promised for vertibird plans - or better, a working vertibird.''
