easily fixed if you are running DCC. The same model is currently
available from Walthers Proto with a more standard gear ratio
and optional DCC sound.
An undecorated model is the best starting point, but unfor-
tunately they are hard to find. An advantage to starting with
a Proto 2000 model is the paint can be removed without any
harsh chemicals or hard work. The Proto 2000 model was
made with two different-length blower ducts on the conduc-
tor’s side as seen in [3]. While I started with a model having a
long blower duct, I highly recommend finding a model with the
shorter version as seen on the Santa Fe unit.
Getting started
I built MEC 610 as a contest-quality model; it is up to you how
much modification and detailing you want to do on your model.
My starting point was the Seaboard System unit shown in [4].
