The thing that got me, was the line which said it wasn't viable to run 82/83 between Heworth and Concord - due to low passenger numbers.
But in the next breath, they tell you to use the 4, apparently the 4 is having its frequency increased.
Does the 4 justify an extra bus? Certainly not between Heworth and Concord, cos numbers would have meant the 82/83 were viable...
