Digital Control
In standard analog DC mode, your model still operates under digital control. The
PS3 advance speed control system converts track voltage into digital speed
commands. Your model will run smoothly and consistently at any speed regardless
of load, hills, or curves. If you are a DCC user, you'll quickly learn to appreciate the
precision of our speed control and linear speed curve. DCS users will enjoy the
added benefits of controlling speeds in increments of 1 scale mile per hour displayed
on DCS controllers or easily changing acceleration and deceleration rates
independently without any discussion of bits or bytes. To be clear, DCS is NOT
DCC.
Lights & Smoke
As you read on, you'll notice there are no instructions for replacing light bulbs in
engine
your . That's because there aren't any. We use specially designed and
controlled LEDs to create realistic lighting effects that occur automatically. Again,
NO PROGRAMMING!! Just come to a stop and watch as the headlight dims
automatically in accordance with rule 17. Of course, as you pull away, the headlight
HO Steam engine
returns to it's fully bright, yet warm, glow. Your new includes
realistic Classification lighting with appropriately colored LED's in the boiler. We
even included a light in the cab so the engineer and fireman can see to do their jobs!
MTH is renowned for our realistic smoke systems. When the smoke is on, you will
experience copious puffs synchronized precisely with chuffing sounds at 4 times per
revolution of the drive wheels. Of course, when you stop, the smoke wafts out of
the stack steadily, just like the real thing! The smoke behavior applies to all operating
modes, analog DC, DCC, or DCS. With some DCC controllers, you can turn smoke
on and off remotely. In DCS mode, you can not only toggle smoke on and off with
the press of single button, you can actually select from 3 output levels to keep those
smoke alarms from going off!

In analog DC operation, just flip the track polarity or direction switch at any speed
engine
and watch your gradually come to stop, turn on the appropriate directional
lighting, and smoothly accelerate back up to speed. No other HO locomotive has
features like these. There are so many more things to learn and enjoy about the
engine
, we could write a book. But, that's no fun. So, if you haven't already done
so, flip to the Quick Start Guide and let's run your new engine!!
