Actually,as a motorman,there are a few differences about the interior of the R143 and the R160.The R143 has a light blue texture on the walls of the interior,as the R160 is white-or light beige colored.Also,to cover the inside for the route display outside,the R143 inside have a small rectangular screen that gives some advice about the NYC Subway,the R160 just has a picture of a fish or another new one.For the R143,the screen on the top is also surrounded with light blue textures.The R160 has it surrounded with black.I hope this is has help explain everything.Thanks for your time.
