Thanks for answering my questions regarding the SEABOARD "roundroof" boxcars. I have two other questions not regarding the AF-1s or B-7s. 1)What were the different types of steel running boards? I've heard of the Apex type and now the Morton type. Any other types? 2)Sometime ago, I believe, Richard Hendrickson mentioned that the only accurate commercially available Hutchins Dry Lading roofs were on ACCURAIL's CN prototype SS boxcar. I believe this car is in their 4200 series of models. My question is: Is the CN car the only one that can be used or is any car in the 4200 series acceptable? I thank everyone for their assistance!
