Erogenous Zone?
Not really ones that work. I can only think of one more version - Leisure Zone.
I think the 'Dots' allows them just to use the service numbers in the brand rather than using the route details (the Zone examples have no mention of 36/37/38 on them just the core route and the Hartlepool route).
