OPERATORS GUIDE
ESU Factory Decoder Equipped Locomotives - Default DCC Address for All Locomotives: 3
Decoder Reset: CV =
Thank you for your purchase of an InterMountain Railway Company locomotive. This guide will direct you
through basic operational and decoder functions, shell removal instructions, and maintenance tasks. Should you
have any questions that are not answered in this guide please feel free to contact InterMountain service and support
at the contact information listed above. All HO scale locomotives are factory equipped with an ESU decoder.
Sound locomotives have a LokSound Select decoder and non-sound locomotives have a LokPilot decoder.
Sound On / Sound Off (F Function Key):
Sound Equipped Locomotive Only-
Upon placing your locomotive on the track, you will not hear any sound. You must press the F function
key in order to get the locomotive's prime mover started. The LokSound Select allows the F8 function
key to create a more realistic operating experience and is not simply a “mute” button. This is done so that
both the start-up and shut down sequences can be heard without any CV changes. This also reduces the
power-up drain on your DCC system’s power booster. The F8 function key operation can be changed to
allow track power to start the prime mover by setting CV32 to 2 FIRST, and then CV387 to 32. A
prototype locomotive’s horn and bell can still be operated with the prime mover shut-down as long as
enough air is available. The LokSound Select decoder operates in just this way!
Locomotive Start-Up Delay:
Sound Equipped Locomotive Only-
Prototype locomotives do not move until the locomotive has been fully started, air pressure built and the
prime mover has settled into idle. Just like the prototype, when you first place your new locomotive on the
track and press F8 to start it up, the locomotive start-up sounds are heard. The locomotive will not be able
to move during the start-up sequence. Once the sounds settle to idle and the throttle is increased, the
locomotive begins to move only after the prime mover has reached notch one. Although this behavior is
very prototypical, it may not be preferred. This start-up delay can be removed by simply changing CV 124
to a value of 0. This will cause the locomotive to start moving immediately when the throttle is increased
during the locomotive start-up sounds.
Operational and Decoder Functions:
Sound Equipped Locomotive Only-
With your Digital Command Control (DCC) System you have the option of multiple horns, prime movers,
bells, and brake squeals. All are changeable with CV48. No booster is needed! Each individual sound has
a separate volume control, and up to 8 different sounds can be played at one time! Not only that, but as
new sounds become available and firmware gets updated, you can at any time, hook up to the ESU
LokProgrammer and update your decoder! Along with outstanding sound, ALL LokSound decoders give
you the benefit of the industry leading ESU Motor Control. You’ll see the difference instantly as the
engine smoothly accelerates across your railroad! You also have the option to use one of MANY lighting
effects on any one of the 6 function outputs!
Extended Addressing:
Most DCC Systems give you the option to enter a 4 Digit Extended (long) Address. Please refer to your
DCC System's manual for guidance as to how to do this. If your DCC System does not have this feature a
full list of values and instructions are available on-line at www.loksound.com.

CV4 Sound Selection Table:
This factory equipped LokSound Select sound decoder was programmed specifically to be correct for the prototype of the model it is
installed within. You may desire to have different sounds. All sounds can be changed with CV48 and your DCC System. The value for
CV48 is calculated by adding the values for the prime mover, the horn, the bell, and the brake squeal selection desired using the charts
below. As an example, the EMD SD40-2 default value would include: Prime Mover = 0, Horn = 6, Bell = 0, Brake Squeal = 0.
Total = 0 + 6 + 0 + 0 = 6 (Default)

Direct Current (DC) Only Operation:
Your ESU decoder equipped locomotive operates on standard DC, but does not operate like an old style
DC locomotive. For those folks that operate exclusively on standard DC, we have a DC plug available
that will replace the decoder in your locomotive. This is available by contacting InterMountain at the
email address or the telephone number listed above. Ask for the 21-Pin DC Circuit Board Plug.

SHELL REMOVAL INSTRUCTIONS
FT/F3/F7/FP7/FP9 units:
1. Place the locomotive on a soft surface or foam cradle.
Remove the front coupler from the locomotive (required for
'A' units only) by unscrewing the Phillips head screw. Gently
slide the coupler box from the shell and frame. The coupler
box may need to be disassembled in place and removed as
separate pieces. Keep the pieces together for re-assembly.
2. To remove the shell, gently slide your fingernails under the
plastic skirting on both sides of the unit. Pull outward
using a steady controlled pressure. Be gentle and take
your time to avoid damaging any of the locomotive details.
3. Once the die-cast chassis begins to slide out from the shell
take care to guide the front and rear portions evenly. Do
NOT wedge the chassis against the body shell.
4. The chassis should drop out of the shell to reveal the
mechanism and electronics.
5. To reassemble the locomotive, place the shell over the
drive mechanism and gently press downward and evenly
until the shell snaps into place.
FT ONLY: Included in your package is a longer draw-bar set. This allows for using your locomotive on tighter
radius curves. Utilize the provided screw to install the draw-bar of your choice.
MAINTENANCE TASKS
Your InterMountain locomotive is designed to provide hours of enjoyment with little or no maintenance. On
occasion the drive gear mechanisms should be lubricated. Utilize a plastic compatible lubricant such as Labelle®
107 Oil. To lubricate your locomotive place a few drops on the gears of the drive mechanism. Only a small amount
is required.
Service Needs: Although rare, at some time you may require service for your locomotive. Please contact
InterMountain Railway Company service department by either email ([e-mail]), or
telephone [phone]), whenever you have a question or need a repair.
Resetting the decoder solves 95% of the decoder related issues we handle.
