longer curve Track

[Anonymous]

I have a question of why doesn't American manufactures run a 23.5 or 25.5 radius track for passenger and longer freight cars being produced.
I found the two above curve track through Rivvarsi in Europe and purchased the 23.5 but lost my connection due to a buyout.I am now forced too use 22" or flex track which I have went to, Those of us that deal in Long Passenger train's would like to see some manufacture make a larger radius track to add to are arsenal of trackage.
