I attempted to detail a couple of Atlas center partition cars, I got a lumber load off eBay and some silverish grey button thread to simulate cables from a craft store. It took me all day to complete and think they came out pretty good.

Nice looking cars sir.

You'll certainly want to get the second one loaded, to hide all the decrepitude on the centre beam!

Very nice! If I may as a observation. Should watch the rust though.. The majority of the CBs I see doesn't have all that much rust.

No problem. I've seen rusty CBs but,the majority had standard weathering like grime and spots of rust. Come to think of it I haven't seen that many true rust buckets in years. I recall seeing a old white Soo Line gon had rust along the ribs and was grimy every where else.

Looks great. If you want a really realistic strap try get dental floss (flat one) and paint it black, perfect for replicating straps and gets really tight!
