if you want to suggest things i would recommend you do them like this https://forums.dovetailgames.com/threads/new-route-essen-hbf-to-münster-westf-hbf-with-flirt-3-br1428-and-db-br-146-0-modern-dosto.33735/
Spamming the suggestions forum with little to no effort put in to it really won't get you anywhere. Please put some thought into these for example, what is the train, who uses it, who built it, where does it go etc. I would like to see this but for the benefit of anyone who has absolutely no idea what this is, please add a paragraph or 2 at least so people won't need to scour the internet for information. Think of it like homework, you are finding information about a topic a teacher has given you, not the other way round (the teacher finding out about the topic because there was no information from you).
