Mike,
What a beautiful locomotive! The lines are so clean! It must be a joy to behold when she runs! She'll look great with the "proper" coaches you've in mind for her!
To Paul's point, yes, having a theme is a must! Just deciding "make it look like Hawaii" has allowed me to pass on lots of cool things! I still have some Euro items (like the LGB Zillertalbier coach) I would like "just because," but my efforts and acquistions are largely aimed at bringing the railroad into a set place and time.
Paul, good luck on your hunt! The Krokodil really seems to hold its value! I saw the Sachsen availably locally once when a hotel ditched its Christams layout. They had everything on a POLA or LGB Euro wish list and multiple Bridgewerks power packs and throttles to boot. Too bad it was on a different island, or I would've sprung for the collection, parted it out, and still made a killing. There is no local market for this stuff, and I always wondered what happened to that collection...
Happy modeling Mike and loco hunting Paul, and Happy New Years to all!
Eric
