List FAQs



Q: I cannot create terrain using the T key
A:  In order to create terrain based on Digitally Elevated Measurement data you will need to obtain the correct files in .HGT format. Free global data can be obtained from NASA at the following location*:


Once you have downloaded the data relevant to your route, it must be placed in the correct folder for RailWorks? to recognize it. If it is not present, it should be created manually by right clicking and selecting New >> Folder.

  • C:\Program Files\Steam\steamapps\common\railworks\DEM\SRTM

Place the .HGT files in this folder.

Load up RailWorks? and enter the route you wish to add terrain to. Once the route has loaded, enter the World Editor and navigate to the location of your choice.

To generate DEM terrain, press T on the keyboard. This will generate terrain heights for the tile you are on, as well as one tile in all directions around you (usually equating to a total of 9 tiles). To continue adding DEM terrain, follow your route to a point beyond the 9 tiles just generated and press T again.

Repeat this process along your route until all the terrain has been generated.

Q: I cannot fly to the long/lat that I want
A:  The jumping facility in RailWorks? is limited to around 600 miles from the origin of the route (tile 0,0). If the co-ordinates of the location you wish to jump to is beyond 600 miles you will not be able to jump there.

Q: Are there any track laying tutorials I can follow?
A:  Narrated video tutorials for various tools in RailWorks? can be found via the Support page of the official website ( or alternatively they can be located here: (external link)

Scroll down the list of the right hand side and click on the video you wish to view.

Q: Junctions do not render when I join track together, why is this?
A:  For junctions to render, you need to use the same track type for all diverging or converging tracks. If you wish to use a different texture for a diverging track, you will first need to create the junction using the same track type, and then extend the diverging route further using your chosen track.

Once you are happy with the junction, use the ‘Blend’ tool to blend from one track texture to the next and create a seamless change on the diverging track.

Q: Junctions do not render even when I use the same track type, why is this?
A:  Once you have connected tracks together to make a junction, click the Weld Tool icon in the top left menu. This will generate a ‘weld’ box above each junction that is valid. To render your junction simply click this weld box.

Q: How do I weld two parallel tracks into 1 with a Y junction?
A:  Lay the two parallel tracks to the point you want the junction to start.
Then lay a single piece of track centred on the middle of the previous two sections, Switch back to your two parallel tracks and, with the snap to track option switched on, draw out firstly corners turning towards the single piece and then snapping into the single piece of track.

Repeat this for the other track.

Once you have both sections joined to the single track you can start removing unneeded bits of track leaving just the Y junction.

Q: Can I change the season while editing a Scenario?
A:  A season cannot be dynamically changed while playing. Only one season can be used per session. However it is possible to change the season from one to another in the settings of a Scenario.

Simply bring up the Scenario properties by clicking on its associated scenario marker, and selecting the season from the drop down menu in the Properties tab.

In order for the change to take effect you will need to re-enter the game and then return to the editor.

Q: Can I change the time of day while editing a scenario?
A:  Time of day can be altered by opening the scenario properties and clicking setting a new time and date in the appropriate fields.

In order for the change to take effect you will need to re-enter the game and then return to the editor.

Q: How do I turn off the giant spheres seen in the World Editor on the Default routes?
A:  These are sound emitters and their size denotes their effective range. To turn these off, click on the monitor icon in the top left window, and then uncheck the speaker Icon in the bottom right of the window that appears to the right side of the screen.

Q: How do I add Seas and Lakes to my route?
A:  Water is placed as a tile object just like other structures. These can be located at the bottom of the list under the Foliage & Water filter in the Browser tab.

Q: How do I create a platform perfectly aligned to the track?
A:  Although platforms can be created stand alone using the same method as laying track, this can be a difficult process if the station is required to follow a bend. So to combat difficult trackside object placement where you wish for a fence/wall/road/platform to perfectly follow the alignment of track, RailWorks? features the Offset Tool.

To use this tool first select the Linear Selection tool. Highlight a length of track where you wish to place your offset object. Click the Offset Tool icon and you will see two yellow lines with arrows appear at one end of the selection.

These lines indicate where the centre of your offset object will be placed in parallel to the track. To adjust the distance from the centre of the track, there is a numerical value field in the bottom left window. Changing this will alter the position of the offset lines in real time.

Once you are happy with the position of the offset lines, go back to the middle left window and choose the object you want to offset. Once selected simply click on the arrow of the line you wish your offset object to follow.

Note: If any red triangles appear on the track anywhere along side your offset yellow lines, the offset tool will not cross these. What you will find is there will be another set of arrows on the offset line that you will need to click to continue your object beyond these red triangles.

Q: How do I enlarge my Area Marker / Decal / Water Tile?
A:  Once you place an Area Marker / Decal / Water Tile you can resize it by zooming the camera close in and left click dragging the small grey triangles in each corner and on each side.

Q: Where can I find the ObjectSet Filter for adding additional content?
A:  The ObjectSet? Filter menu can be accessed from any World Editor Mode. When in the World Editor, pull out the middle left side Browser tab, and pin it open. Next, click on the small Blue Icon with the Orange Triangle in the corner. This is located in the top left corner of the middle browser window.

When pressed, the ObjectSet? Filter menu is opened on the right hand side of the screen. Pull it out and pin it open. From here you can add additional content sets by placing a tick in the check box next to a developer’s product. Developers can be chosen from the drop down list at the top, and all the products you have installed, related to each developer can be found listed when a developer is selected. Note that you cannot remove ticks from added content sets.

Q: When I use newly downloaded trains, only the couplings show up
A:  Some downloads available on the internet require the end user to an original item of rolling stock that this new one references. If you do not have these elements or then it will not display correctly in RailWorks?. Please see any ReadMe? or instructions provided with such downloads to resolve these problems.

Q: What are these Red Triangles on my track?
A:  Small red triangles found at various points along the track network indicate the boundary between two ‘Ribbons’. Track in RailWorks? consists of two elements:
  • Sections - The pieces created between each click of the mouse when laying track. These are also the pieces that are individually selectable.
  • Ribbons - These are lengths of multiple 'sections' of track that RailWorks? breaks into render chunks. Ribbons vary in length depending on the complexity of the track. The converging point of a junction also forces the creation of a Ribbon boundary. Using the split tool also forces a new boundary at the split point. RailWorks? then loads in and renders track on a 'per ribbon' basis.
Also observable on the track network are large red rectangles. These rectangles indicate junctions that have failed to render properly and thus are missing the blades and guard rails. This is usually due to either use of non-matching textures in the converging track, or a section of track in the immediate vicinity of the diverging end is shorter than the area needed to render the junction detail.

Q: When I try to edit existing routes the Track and Trains icons are not accessible, why?
A:  By default there is a padlock active on the default routes. It can be located in the bottom right corner next to the play button when in World Editor mode. This lock prevents accidental editing of provided content in case these edits subsequently cause the provided content to fail to work as intended. If you click this lock to turn it off, you can gain access to the track editing and scenario tools for that route.

However, please note that due to the way in which Steam provides updates to RailWorks? default files are considered ‘core’ assets. These assets are protected to ensure that RailWorks? always continues to function as intended. Therefore we do not suggest users directly modify any default content in RailWorks?.

If modifications are desired, it is recommended that that users duplicate the files concerned, and then make changes to these instead.
