Double-door, triple-door and quad-door (artics) are a way of handling things when tickets are to be bought before the ride - the way it SHOULD be. Then, standing space, which allows more passengers on board than with sitting places (money, money, money :P ). Of course you could do it that way >> http://phototrans.eu/14,5...Neoplan_N4016NF_687.html >> but then you've no space for a buggy (no money, no money, no money). Anyway...

This is your best (I think...) citybus interior arrangement:

So, what do we have...
- three doors - make that two for IRL.
- wheelchair/buggy space
- 33 seats - a decent amount for a 12m citybus
And then there's one thing that I wish to make a whole topic about - PIS (short for Passenger Information System, which basically sucks here). Includes an interior display (infos, next stop, date, time, etc., etc.). Then there are ticket validators (those grey-and-yellow boxes around the place), which are needed for a system where you buy the ticket before boarding (why the hell does it work in Poland and Germany and a few other countries and not in Ireland?).
Oh, and a full-lenght low-floor - I don't really think it's necessary in Ireland, though.

Fare evasion? No problem - severe punishments must be put in place (maybe 100 Euro) - one city in Poland, Szczecin, has 242PLN (a lot in Poland - it's actually the biggest fare evasion punishment price) = 55 Euros may not seem much but when paid over and over and over again...?

So - your arguments AGAINST dual-door buses are... well, what? Useless?

EDIT:
Isn't your RTPI the IBISplus panel? I think it is, since RTPI in Cracow trams uses the exact same IBIS system as here - the Siemens IBISplus.
