They trialled it on quite a few buses, but because of the rural nature of most routes, the radios failed to work on the majority of services. The 43 in Durham, the radio only worked between Durham-Ushaw Moor, but not through to Esh Winning, so it only worked for around half the route.
I was mentioning the Northumbria 43 Newcastle To Cramlington.
