TSR’s and signal delays are core features so don’t need to be activated on a per route basis. Additionally, TSR’s in core are all 40mph as far as I’m aware and as the core is off limits we will not be doing anything with them beyond that. Hope that answers the question
Unsure why its Tonbridge but a big network of services have opened up for you. Could have extended south to Tunbridge West not Hastings as that could be another route. Ran by Southeastern. Like the Redhill services by Southern.
To be honest is there really any point? Tonbridge to Tunbridge Wells is like a 10 minute hop, and you can't drive a service from Strood to Tunbridge Wells. If it were me I'd probably include it on a South Eastern Network route. Then you can have proper runs up to London.
It's Tonbridge because Medway Valley Line services go to Tonbridge. We wanted all the MVL services to be fully playable on the route, this way they are.
