I'm looking at buying a new passenger set, based on the prototype are of my layout. It is the "Overland" (Melbourne/Adelaide) that was first run in the early 60's. Teh commercially available sets have the latest logo (new company acquisition) on them, however the cars are original of the era (and the protptypee that is running today, still is the original scheme, except for the new logo. Is there a way of removing decals from commercially produced rolling stock?
