I recently bought a set of the ribbed-metal 60' streamlined passenger cars (in my case Burlington).  Does anyone know if there are end-of-car diaphragms available either through WBB or elsewhere?  Thanks!

I'm seriously considering buying either the J-Class or the S2 locomotive to pull my classic K-Line Streamliners ("Fleet of Modernism") passenger consist.  The cars are about 14" long each.  I believe these Locomotives are O-Traditional or near-scale.  How can I learn how these units will match up to the consist in scale?

I am looking at a set of Williams O 15" 6 wheel silhouette passenger coaches.  They appear to be from either a starter set or a low-end price point set of coaches in Pennsy road name (there are four of them).  Would anyone be able to help me find out what the minimum curve is?
