M.T.H. SD70ACe User Manual

M.T.H. HO
SD70ACe/SD70M-2
Diesel Engine
Congratulations! You've just purchased the most
feature-rich and technically advanced HO diesel
locomotive ever produced! This highly detailed
model includes a broader range of features than
you’ll find on any other HO scale diesel, including
operating flashing ditch lights; smooth
performance from a three-scale-mile-per-hour
crawl to full throttle; “cruise control” for steady
speeds regardless of curves, switches and grades;
built-in decoders for DCC and the M.T.H. Digital
Command System (DCS); and a full range of
sounds recorded from a prototype Union Pacific
SD70ACe. If you’re looking for modern motive
power that’s accurately detailed, smooth running,
and a great deal of fun to operate, it doesn’t get
any better than this.
