I’m building some 1:20 passenger cars (eventually), and I needed an engine that looked larger than the Annie, since it’s done in 1:22.5 (sort of).
I bought an Annie on ebay and began replacing things.
I put on a new pilot, new boiler, domes from Accucraft, cab from Vance, and widened the tender.
An early comparison shot:
The tender was lengthend and widened, and recovered with a styrene shell.
I used nbw for the bolts on the front of the smoke box. After that, I tried slicing styrene rod for the rivets on the sides. I was able to reuse some of the parts from the Annie, such as the compressor, bell, headlight and piping. I made new airtanks from styrene tubes.
I put in batteries and RCS in the tender.
Here you can see how small that coach looks behind the finished locomotive.
And out on the track, it looks right at home hauling a 1:20 train!
Siince the Annie is a model of a very large NG ten wheeler it is already very close to the right proportions in 1:20. I upgraded mine by enlarging the cab (taller and wider) and making the tender wider and taller as well. When viewed next to the B’mann Connie, it looks just about perfect.
BTW, I’m bashing some B’mann coaches to 1:20 by making them longer (scale 44’), wider, and taller. It’s a lot of work but I think it’s probably less work than trying to build them from scratch.
The domes are STEAM DOME, K-27 #463 1:20.3 101011208, SAND DOME, K-27 #463 1:20.3 101011209.
The PVC pipe is 3" OD that I got from Plastruct.
The tender is about 13" long x 5" wide and about 5" above the railhead. I basically scaled up the HO plans to 1:20.3 and used that for the tender dimensions.
