Hello Yardmaster and Fred Klein,
Thanks for both of your replies, both were very helpful as I just completed my first removal on a 26' boxcar #27099. Once the top was removed, I understand how everything works. I used a chisel blade on my Xacto knife to gently pry on each corner. I will also add that in future removals, besides the brake wheel and shaft, I will remove the couplers and trucks to prevent damage while I'm concentrating on the roof.

I'm new to this gauge but have started to purchase Bachmann equipment while building the benchwork and laying track. I purchased several boxcars, ventilated and regular, and am interested in detailing the inside area that is visible with the doors open, adding visible loads and some weight. No paperwork was in the kits on removing the body so I'm looking for tips on how to remove the body from the frame without doing any damage.
