I also remember someone posted a comment here years ago that 'a
Citaro on 74 is as useless as a van on 96'.
But 74 still has so many Citaros even until now.
And he also said, 'Did 74 pax offend SBST?'
I think it is because 74 is a student service that makes
losses due to concession fares for students, so SBST
refuses to upgrade 74. Anyway someone else once said that 74 is the
'biggest student service in Singapore'.
But I don't think this will go on any further. I think 74 will
become full DD soon since SBST is no longer collecting fares.
74 doesn't upgrade as of now. Reason being is there are multiple
of services floating around, such as 52/184 to the nearest MRT
stations. Got DTL, but they need to serve the connections.
Anyway, if need be in 2018, it will become full DD.
