Thanks James,
Way more detail than I was looking for but your response is greatly
appreciated. I really was just wondering what everyone was doing height
wise, and if I needed to make my caboose taller (to make it as tall as
my engine). I plan on making my box cars, my covered hoppers (if I ever
get around to building one), my uncovered hoppers (I hope to build one
soon), and now my caboose the same height as my engine. I will make my
tank car a bit shorter when measured to the top of the tank, and my
autorack a bit higher that my engine.
When ever I build I consider the dimensions if I can find them easily,
but mostly I just try to make it look close. Once I decide on an
important detail, like the size of a truck or the distance between the
wheelsets, I build the model relative to that dimension. Now that my
engine is done I need to build everything else relative to that size.
Thanks,
Chris
