O Scale (1:48) Budd Silverliner (PRR Version) body shell. Stepwells available separately. (We have two Silverliner Stepwells available on our Shapeways page; please make sure you select the correct ones as they are dimensioned differently. Select the ones marked 1:48 scale for this shell.) Shell measures 21.25" long, correct scale length for O scale. Shell in White, Strong and Flexible will give nice detail but the surface is a little rough. Some smoothing and painting will yield a nice shell. Shell is designed from blueprints and measurements of the real vehicles, which were retired in June of 2012 by SEPTA.
