So i have another idea. I will be happy to have option where i will can delete any speed limites if i will make some mistake and station if also i will want remoove them. I can imagine interface of creator like carts or buttons with steps of creating. It will be more confortable when i will need change only one part of my route, stations or vechicle, or another parameters like speed limites. Another idea, will be great to can choose another vechicles for trains from schedules. For example, if i will make IC and regional i will want have another loco for IC and trainset for regional train.
