Agreed. All I'm saying with the chime thing (or any other seemingly trivial design details, like the choice of fabric colours/patterns inside, exterior branding, striping etc.) is that I don't want this to be left to someone who doesn't care and just does whatever they want to push it out the door. People who "get" good design/UI (and I think there's a lot of those people here, based on the above comments!) understand that it's those little things that improve the overall ridership experience. And for people like me who obsess over details, it puts us at ease 
The trains are the face of the system - the things the passengers will interface the most with.
Goldlinq went to some huge effort to get a third-party design team involved to come up with a nose cone design and paint job that evoked the visage of a surfboard for Gold Coast's LFLRV's! I'm not saying we go that far. I just want someone to care and put some thought into the options that are easy to customize, like the colour of the exterior, interior, illumination and audio cues, that's all.
