Since I've developed an affection for CB&Q's fluted stainless steel locomotives I decided to tackle #9908 'Silver Charger' the locmotive of 'General Pershing Zephyr'.
I use an USA-Train streamliner (a diner) for the shell. Trucks will
be either a poered front truck only (like the prototype) probably using
an USA-Trains' SD-40-truck and turning the side frames into
'Blomberg'-look-a-likes. Since the train with #9908 will only consist of
three cars or so this might be sufficient. It may also be a solution to
get more powr using an Aristo-FA-truck for the rear...however, thia
would depend on the speed's matching of the two types.
Shortened, the windows filled and resting on tweo FA-trucks - it'll be a long way to resemble the beautiful #9908....
