Based on SGwiki, a KUB Euro IV can have a capacity of 87 people
due to its greater standing space. If a 12m 2 stairs DD can hold 94
pax, it might still be better to deploy SDs with the Euro IV design
with more standing area. No matter how much standing area is made
available on the lower deck, there still needs to be a minimal
number of seats to cater to the aged and disabled. And these grps
of ppl frequent on feeders, with Singapore facing a aging
population. So it might still be wiser to use SDs and increase
frequencies abit as opposed to exploring 12m 2 stairs DD (I.e. if
LTA doesnt even want to use bendies for feeders)
