X35: Newcastle - Gateshead - Heworth - Wardley - Downhill - Southwick - Monkwearmouth - Sunderland City Centre - Doxford International - Houghton-le-Spring - Hetton-le-Hole - Easington Lane - South Hetton - Easington Village - Peterlee - Hordon - Blackhall - Hartlepool
You want to pay the money to fit 9 buses with tachographs plus a few of the red spares as back-up? Unless you did advertise a through connection but have it as a split service to avoid the need for tachographs as per the X7.
