"Sunderland fans urged to use free supporter buses to Newcastle for Tyne-Wear derby" http://www.shieldsgazette.com/news/...es-to-newcastle-for-tyne-wear-derby-1-7794760
Many fans will take the train instead so they can drink on the way. I understand why they say no drink on the coaches but its what will put most fans off using them. I am willing to bet no alcohol will be served in the ground to away supporters.
You'd lose your bet, 'cos it's served like any other game . . . . in Sunderland A.F.C. glasses (plastics)
