Found this info about the new cars. https://en.wikipedia.org/wiki/R211_(New_York_City_Subway_car)
I'm with Andy on the yellow handrails. Keep them polished stainless. The paint will scratch off. I don't like the open car ends personally. How are you going to escape the panhandlers that camp out on the trains.
Lack of seats will definitely get a lot of complaints too.
