Premise: Arriva North West and Wales was a division of Arriva that operated bus services around North West England and Wales. It was made up from several previous bus operators including North Western (in Merseyside, Cheshire and Lancashire), most of MTL North (formerly Merseybus), the Bee Line Buzz Company (in Greater Manchester), and most of what was once Crosville Motor Services (in Cheshire and Wales).
Hypothesis: Arriva North West and Wales is still in operation
