The Sevenoaks trains seem fairly well contained, and I'm not sure it's as common to see them swapping between the MML and ECML as much as they did.
A Sevenoaks train is likely easily identified by the egress panels being smashed. It has become such a problem that I doubt it's worth replacing them. You can ride a train that came from Sevenoaks (say picking it up from St Pancras to Hatfield) and as you walk through you'll see the floor covered in glass/perspex.
