F40PH Diesel Operating Manual
QUICK START - BASIC OPERATION
The MTH F40PH contains state-of-the art electronics with several built-in automatic
features for incredibly realistic operation. Despite these advanced features, the 3-rail
F40PH is easy to operate with any compatible standard AC transformer (see the
compatibility chart on page 25). The 2-rail models will operate with any DC power source.
All models are equipped with an operating smoke system that should be primed with
smoke fluid before operating.
Adding 10 - 15 drops of fluid
through the smoke stack should be
sufficient. If you choose to not
prime the units with fluid, turn
the smoke unit switch located
under the leading drive truck to the
OFF position. (See Figure 1) For

operation.
The 3-rail models are controlled
by two DCRU™ electronic reverse
units. The reverse unit operates in
the same manner that all reverse
units function by using forward,
neutral and reverse states that are
entered each time the throttle is
turned on and off or by using the
transformer direction switch (if so
equipped).
The 2-rail model’s
direction is controlled through the
polarity of the DC power source
and operate the same as all 2-rail
DC engines.
The reverse unit is designed to ignore dirty track, dead spots on switches or minor short
circuits without disrupting the engine operation, even at slow, prototypical speeds. Once the
3-rail engine is placed on the track, the throttle on the transformer can be advanced. You
will see that only the engine’s lights come on and that only two dings of the ProtoSound bell
occur followed by the diesel start-up sounds (on ProtoSound equipped 3-rail models). The
engine does not run. This is known as the RESET state and is explained in more detail
beginning on Page 6. The DCRU™ will not power the motors until the throttle is turned OFF
and then ON again. At this point, the engine will now function just like any other electronic or
mechanical E-unit.
On ProtoSound-equipped engines, the diesel engine sounds will
change in volume as the engine begins to move. The horn can be activated by pressing the
whistle button on the transformer just as any horn would be activated. See the sections later
in this guide, beginning on page 7, for more information on activating the horn and bell
sounds.
