My ACF 44 seat coach is the most interior detailing of a plastic car that I have done to date. I even put in some overhead luggage racks. They hide the roof locking tabs. Those Red Cap Line Sleepy Hallow seats and restroom fixtures are awesome!  Unfortunately, Red Cap is no longer in business, but their parts can be found on ebay at times. I am pretty much done with this guy.  Might do a chair for the conductor's desk someday.
