Can/will we have Guard mode and/or suspension for all trains in the future. Like guard mode for the Glossop Line and BCC. And suspension for older routes. All these things could be added to routes without a remaster maybe...
It might take too long Suspension is physics which means changes to simugraph which is a lot of work and it needs to be tested over a very long period of time to ensure the train doesn't go flying to outer space. It also needs to be manually applied to each train. Guard mode depends on the train and operator. Some have guards, some don't.
