    How do I make a smooth, downward or upward gradient on already laid tracks?

    Somehow I'm only able to select a limited amount of tracks with the gradient tool. Sometimes I need to select bigger sections. On TSC you could just select big chunks of track and click on the gradient tool to smooth it out.

    Might take a look at this tutorial:
    https://forums.dovetailgames.com/threads/gradient-plotting-mini-tutorial.76169/

    Not exactly sure what and how you use it but usually with the gradient tool you don't work with pieces of track as rather its/their start and end nodes. You can select multiple nodes at once by holding down Ctrl and clicking on nodes you want to include into the selection. If it worked a small blue line appears which connects the nodes visually.

    Then you can drag the blue arrow of the move pivot down or up and the tracks change their gradient all at once.

    Yes, I meant those nodes. The problem is, you can't select more than 3 nodes at once. Or at least I haven't figured how to do it that way. Either that or it doesn't allow you to select all nodes in 2 km of track, for example. Especially if it has more than just 3 nodes.

    Tried it with 24 nodes. Seems to work.

    Edit: the lenght also does not seem to be a problem, here 30 nodes with 3 track pieces of around 400 meter distance (Spiderman would be jealous :)):

    Yeah but try and select tracks over several different map tiles.

    If you take a closer look at the second image, you can see that the longer pieces of tracks cross from a landscape tile where Lidar has been applied to a SRTM only tile. So again, need to pass out and can't replicate. Works everything for me.

    I don't know if this is what you want but you can try selecting each node one at a time and on the right enter the node gradient in either Node Gradient 1/2 or Node Gradient 2/2. For example in the image below first set the gradient of node 1 then set the gradient of node 2, etc. That's the only way I know to make completely smooth tracks. I haven't found something that straightens gradients between two nodes or something like that.

    Of course you need to know the gradient first. So either trial and error or calculate it.

    At the end you can use vertical curves but best do it after all tracks have been laid.

    Thanks everyone for your help and advice.

    RobertSchulz Here's my main issue. I can't seem to select a bigger amount of nodes. And I can't select both tracks at the same time either. So this will eventually create problems... Unless of course I misunderstand how the "Transition Tool" works.

    Ahh, I know now where the problem in our communication is. We both use different tools. You use the "Transition Tool". I didn't even work with that yet - quite unsure what it's purpose is to be honest - I think it's used to calculate the best angle and distance of a curve based on the indicated Vmax. I'm building a silent 60 km/h route so I didn't bother much with this tool yet. Might be more important for a high speed line. If anyone in here knows more about it, please let us know.

    What I use to select multiple nodes and change the height of each individual or multiple nodes is the "Node Edit" Tool which you get when clicking on the 8th position in the list (the track icon with the upward arrow) or using the shortcut Ctrl + Alt + H.

    BTW: I finally know what BRD stands for (aside from the same abbreviation for the state of germany). Nice channel! Is this wolf like a mascot for the national portugese railway?:)

    The Transition Tool should be about the same tool as the "smooth gradient" tool on TSC. It serves to create a smooth curve between two gradients. However, on TSC it can calculate many different nodes and make an average of the whole thing. :) I know how to change the gradients with the node tool, but I want to make them smooth instead. It should be doable with the Transition Tool.

    In regards to the railway dog: I'm not a mascot. :) I do this for my own entertainment and because of the community involved with this type of thing.. Thanks for your compliment!
