Back on topic..
Trains a bit alright I suppose. At first I liked the thought of it loosing its branding, but to be honest it has gained such a reputation as 'The Pepsi Max' that I doubt it ever will truely loose its branding as such a high percentage will still refer to it with its' 'Pepsi Max' tag.
Agree with the comment on the can the train goes through, I say replace it will a tunnel with more strobes and tons of smoke. Yeah, that'll be good.
Seriosuly though, if BPB don't hunt for a new sponser, impressive stuff. That's not like them really.
