OPTIONAL HORNS
Your decoder comes pre-loaded with optional horns which can be used to customize
your decoder. The default horn is the Holden M3H, which was installed by GMD
when the locomotives were built. CP FP9A locomotives were delivered with the identical-
sounding M3HR (one bell reversed), and starting in 1961 all CN FP9A locomotives also
received this variation.
We also include an optional Nathan K3L (used by VIA Rail Canada) and a Nathan
K5LA (used by some tourist railways after the FP9As were sold by VIA).
Horn selections are made in CV 115. A value of 0 will activate the Holden M3H; a
value of 1 will activate the Nathan K3L; and a value of 2 will select the Nathan K5LA.
BELL RING RATE
Our bell sound is also recorded from a real FP9A and at its default setting rings at the
same rate as the bell on the loco that we recorded. You might think the bell sounds
fast. That’s probably because you are used to freight locomotives or modern passenger
locomotives. The FP9A did indeed have the fast bell that is on your decoder. We re-
corded three different FP9A bells and they all rang at roughly the same rate. Obviously,
different locomotives had slightly varying rates, especially if there was a bad air leak!
You can customize the ring rate of the bell sound by entering a value of 1-5 in CV 114.
The default value is 1.
