But the Scania E300s only appear on the 4 every now and again? There is going to be 6 spare E200s if the proposed service changes go ahead (1 from the 4, 2 from the 5, and 3 from the 18/19) So if anything the X24 will be more than likely be operated by the surplus E200s- however I cant see them lasting long on there most of them probably haven't been above 30mph in their life.
