Reference: Buskers, themed cabins for a better MRT experience: LTA
Talk about visual noise. I still remember the horrendous Dim Sum Dollies jingle. Why not just keep it simple, LTA, and focus on the service of actually bringing people from one place to another?
So unless your themed cabin is some incredible idea, please, don't.
You know every time I want to look at how minutes there are to the next train coming, and I see an ad of some movie trailer? Do you think that makes my journeys more or less harried?
