QBP Liverpool and Wirral

RE: QBP Liverpool and Wirral
Stagecoach Tridents are Euro3, and exhaust traps take them up to Euro4 for particulates, which is the baseline requirement for the QBP IIRC.

Darts are Euro4 anyway, so meet it anyway.

I've said it many times before and I'll say it again; if loadings consistently justified single decks, or even doubles, you'd have them. The fact that you have darts means vehicles aren't full enough for long enough throughout the day.
