@Cyterion, many thanks my dear friend. As far as I can see, you are the only one who is very active in Metro station creation and apparently only (all of) your stations are working part of MOM. So my sincere thanks to you for providing information to me. Hope your brother completes the software quicker to relieve most of us from using the deeply terrible HEX editor. Cheers and all the best!

Hello, I have further information for your metro station project: To add new metro platforms and new pedestrian underground paths in the editor you will need the following three mods: "Advanced Buildings Editor", "Prefab Hook (Mod Dependency)" and "More Network Stuff" - With these three mods you are able to create and delete metro platforms and pedestrian underground paths. Unfortunately the modifying of the paths in the editor is tricky - so maybe edit the paths manually following the tutorial: https://steamproxy.net/sharedfiles/filedetails/?id=430647273 . Currently my brother program a good software to modify paths more easier. If the software is finished, I will inform you.
