Rest assured Arriva won't be spending a penny on new buses until the long term implications of the covid carry on are understood. Throw in the new SE Northumberland rail link sheduled to open in 2023 and I'd imagine the fleet numbers needed to cover demand could shrink by 20-30% over the next few years. I'm sure there will also continue to be a steady stream of 10-15 year old vehicles arrive from down south to replace the oldest dross up here for the forseeable future as well.
