Thumbing through an older book called "New England ALCOS in Twilight" I came across a single picture of an RSD15 which looks like an elongated RS11 on 6 wheel trucks. No mention of whether it was a Schenectady or MLW product. It caught my interest and I'm thinking of building one using an Atlas yellow box RS11 and an RSD4/5 for the trucks.
Was an HO model ever produced of the RSD15 and has anyone ever seen the actual prototype?
