I agree, although a RTR car can be improved….I changed the corner stirrups of this Walthers Mainline car…..cut off the too thick molded-on ones, and glued finer ones on in their place….much improved…..I’m also not one to buy a car that’s rtr because the model building is what I enjoy the most so adding all the grabs and stirrups and brakes and what not to a freight car just gets my interest
