Making liveries for Rolling Line is very easy. No downloads required and only one I recommend is Photoshop if u wanna make a really good one.

All you need is MS Paint and about 20 minutes and youll have a skin made.

First thing you need to do is find templates. This is an easy task.

You need to go to your Rolling Line game folder under Program Filex (x86)/Steam/steamapps/common/Rolling Line then go to Modding and templates.

Look for the template of what you want to reskin. I did the DX class. Get the rainbow colored one and open it with Paint or whatever your preferred picture editing software is. For this ill show instructions with Paint.

Once open, your gonna look for the small paint bucket near the top left.

Then click a color, and fill in whatever body panels you want.

DO NOT paint the back or it will mess up the whole thing and you have to start over. Use the zoom to your advantage.

Once thats done, you can make your own logos and road numbers.

Click the A next to the paint bucket. Then click where you want your logo or road numbers.

Edit the size and font to whatever you like and feel free to use the Bold, Italic and Underlined settings too.

Once your badges are made, hit File, then Save As, find the customliveries folder in your Modding folder, and save there as whatever.

Okay, now that you have made your skin, we will load it in Rolling Line.

Open up the game in VR or normal. It doesnt matter which.

Load a save.

Hit Esc to go to the menu, then click Liveries.

Click Add New.

The locomotive type should show up along with the skin. You can apply any skin to any locomotive, but that breaks it. Use the correct loco for the correct skin. for example DX skin Diesel locomotive.

Now that thats done, hit the Spawn Wagon button off to the right. It should appear in your hand.

Place it on the tracks, survey it, if it looks good save it as a configuration.

Now you have made and are able to use your skin. Congratulations.

Now that you have saved your locomotive for your use, you can upload it to the workshop for other people to use.

Now you will capture a thumbnail. Place your locomotive and whatever else you want and take a picture of it.

Then, at the very bottom, is a button that says Upload to Steam Workshop. Click that and it should upload.

Congratulations. You have made and uploaded your own skin for Rolling Line.

Hopefully this helps anyone it can. I made it as easy as I could.
