Train Sim World (abbreviated to TSW) is a series of train-simulation games developed by Dovetail Games. There have been eight iterations, including the initial Train Sim World: CSX Heavy Haul in 2017, after which came the Xbox One exclusive Train Sim World: Founders Edition in 2018. Train Sim World was released the same year, followed by Train Sim World 2020 in 2019 and Train Sim World 2 in 2020. Since the release of Train Sim World 3 in 2022, there has been a new release every year.
The key people involved with the Train Sim World branch of Dovetail Games include executive producer Matt Peddlesden, senior community manager Alex Gate, community managers Jamie Ringwood and Harriet Morris, and associate designers Michael Alexander and Joe Burgess.
Releases Train Sim World allows players to walk around the game world in a first-person mode. This mode is utilised in tutorials, scenarios and services in which the first-person mode is required to complete tasks such as refuelling, navigating, doing different types of train driving services or changing switches. It was developed in Unreal Engine 4.
Train Sim World: CSX Heavy Haul Released on 16 March 2017, CSX Heavy Haul consisted of one playable route: Sand Patch Grade, based in the United States.
Train Sim World: Founders Edition Released in 2018, the second version was Founders Edition, which was available on Xbox One, containing Great Western Express (GWE). It featured three routes, plus the Sand Patch Grade from CSX Heavy Haul.
Train Sim World Later in 2018, the third version, titled Train Sim World, was released on Microsoft Windows, Xbox One and PlayStation 4, featuring three routes: Great Western Express: London Paddington–Reading, Rapid Transit: Dessau Hauptbahnhof–Markkleeberg-Gaschwitz and Northeast Corridor: New Rochelle–Newark Liberty International Airport, as well as Sand Patch Grade for the Windows version only.
Players who originally owned Train Sim World: CSX Heavy Haul were automatically updated to Train Sim World, with the existing game being renamed and the new downloadable content (DLC) being added to that. GWE was remastered and released in February 2026.
Train Sim World 2020
The fourth version, Train Sim World 2020, was released for Microsoft Windows, Xbox One, and PlayStation 4 in 2019, featuring four routes: Great Western Express, Long Island Rail Road (Penn Station–Hicksville, Hempstead Branch, Atlantic Terminal, Belmont), Main-Spessart Bahn (Aschaffenburg Hauptbahnhof–Gemünden (Main); by Rivet Games) and Northern Trans-Pennine (Manchester Victoria–Leeds) route add-on, as well as Sand Patch Grade for Windows only. 2020 featured a Digital Deluxe edition containing, as a bonus route, Caltrain's Peninsula Corridor (San Francisco 4th and King Street–San Jose Diridon route add-on).
On 12 December 2019, Dovetail Games released the East Coastway add-on. In addition to the Brighton to Eastbourne route, there is a branch route between Lewes and Seaford. The release includes the Class 377/4 and the Class 66.Gateway to the Coastway - Gamasutra, 12 December 2019 Further add-on routes included Rhein-Ruhr Osten (Wuppertal Hauptbahnhof–Hagen Hauptbahnhof), Ruhr-Sieg Nord (Hagen Hauptbahnhof–Finnentrop), Haupstrecke Rhein-Ruhr (Bochum Hauptbahnhof–Duisburg Hauptbahnhof), Tees Valley Line (Darlington–Saltburn), West Somerset Railway (Minehead–Bishops Lydeard), and Canadian National Oakville Subdivision. Several individual locomotives were also released as DLC, including the Class 20 Chopper and the former East German DB BR 143 and DB BR 155.
Players who originally owned Train Sim World were automatically updated to Train Sim World 2020, with the existing game being renamed and the new DLC being added to that version. Despite this version adding the year to the tile, it was the only release to do so, with Dovetail later abandoning the existing release model used by Train Simulator.
Train Sim World 2
The fifth version, Train Sim World 2, was announced on 9 June 2020, with an original planned release date of 6 August 2020. The announcement promoted new features, including the Livery Editor and Scenario Designer. There were two new routes and multiple trains planned for its release: the ICE 3M and Bombardier Talent 2 running from Köln Hauptbahnhof–Aachen Hauptbahnhof, branded as Schnellfahrstrecke Köln-Aachen, and the London Underground 1972 MK2 Stock, with the Bakerloo line. The game also came with Sand Patch Grade route (Cumberland–Rockwood), featuring the AC4400CW, GP38-2 and SD40-2 locomotives. While the route was not new, it had been updated for Windows and was also available on PlayStation 4 and Xbox One with major optimisation to the consoles. The Deluxe Edition also included East Coastway as a Preserved Collection route.
The Preserved Collection allows players to import their previously owned Train Sim World and Train Sim World 2020 bundled routes and DLC into the new game. This meant players could continue using them without the need to pay for them again. Dovetail Games announced the game would be delayed on 16 July, with a rescheduled release date of 20 August, back from the original 6 August. This was to allow them to make Preserved Collection add-ons compatible with their new Scenario Designer. They confirmed that content from this category will not be compatible with their new Livery Designer, due to a change in the way they develop trains, although such compatibility might be provided in a future upgrade (this has since been confirmed; Livery Designer compatibility for East Coastway was included in a February 2021 patch, with more routes to follow). They also announced, within one of their community questions-and-answers livestreams, that their Northeast Corridor route add-on, as well as their Amtrak SW1000R and CSX GP40-2 loco add-ons, were not going to be part of the Preserved Collection due to technical issues.
Dovetail Games unveiled their first roadmap on 18 August, which presented their plans for future additions to the game, as well as the timeline for the additional Preserved Collection add-ons.
Train Sim World 2 was released to the public on 20 August 2020. More DLC followed: Haupstrecke München–Augsburg: LGV Méditerranée: Marseille–Avignon, Southeastern High Speed: St Pancras–Faversham, Clinchfield Railroad: Elkhorn–Dante, Hauptstrecke Hamburg–Lübeck and Scottish City Commuter (Cathcart Circle) together with Isle of Wight: Ryde Pier Head–Shanklin and Arosalinie: Chur–Arosa (both from third-party developer Rivet Games) and Union Pacific Cane Creek: Thompson–Potash (from third-party developer Skyhook Games). The Cathcart Circle Line received an AI addition, to layer in the Avanti West Coast Class 390 Pendolino, with the release of Train Sim World 5 in 2024. The game also included locomotive DLC from all versions, including: DB BR 182, MP36PH-3C, C40-8W, Class 465, DB BR 101, MP15DC, M3 and Diesel Legends of the Great Western (Class 52, Class 101 and Class 08).
