F4 – PFA
PFA in MTH lingo stands for Passenger/Freight Announcements. Your engine is pre-
programmed for the appropriate type of sounds based upon the type of service the
real-life engine used in daily operation.
There are five sound sequences or segments in the PFA feature. Each segment is
advanced by you, the operator.
You hit the F4 button twice on the DCC controller to let the engine know you want it
to advance (this toggles the PFA function on then off to clear the remote for the next
sequence). In most PFA sequences there is a minimum wait time of about 20-30
seconds before it will advance. So, here is how a typical PFA sequence operates:
1. Press the F4 button twice (toggle F4 on then off) to start the PFA sequence on the
engine. You'll hear “Now arriving…” for passenger sound sets and cab chatter for
freight sound sets. The bell will then begin ringing.
2. Slowly reduce the throttle until the train stops at the desired location and speed
reaches zero. Press the F4 button twice (toggle F4 on then off) again and the bell will
stop ringing. You will hear the engine sounds switch from the cab to the station or
yard with all the ambient sounds you'd hear in the real thing.
3. Press the F4 button twice (toggle F4 on then off) again to advance the sequence.
You'll hear “Now boarding…” for passenger sound sets and freight yard sounds for
freight sound sets.
4. Press the F4 button twice (toggle F4 on then off) again to advance the sequence.
You'll hear “Now departing…” for passenger sound sets and more freight yard
sounds for freight sound sets.
5. Press the F4 button twice (toggle F4 on then off) the last time to advance the
sequence. You'll hear “All aboard…” for passenger sound sets and more freight yard
sounds for freight sound sets. The engine sounds will switch over to the cab again.
When the bell begins to ring, advance the throttle to move the engine out of the
station or yard. The bell will shut off automatically.
