This specific soundfile is designed for the 21MTC select decoder and is set up for the LED lighting outputs included in the Athearn SDP40F and SDF40-2 Locomotives.

Amtrak SDP40F:
The design of the SDP40F was based on the EMD FP45 passenger locomotive. Both shared the EMD 645E3 diesel engine, although the SDP40F had 16 cylinders instead of 20. The space saved from the smaller prime mover was given over to increased water capacity. The SDP40F had an underbody tank split between water and diesel fuel, carrying 2,000 gallons of water and 2,500 gallons of diesel. A second 1,500 gallon water tank sat in the carbody, forward of the steam generators which produced the steam needed for supplying heat (and sometimes cooling) and hot water for the train.

Eventually, the SDP40F was phased out as all-electric cars, such as the Amfleet, displaced the old steam heat rolling stock. While the SDP40F was designed with conversion to head-end power (HEP) in mind, the bad press they received, cost to upgrade and overhaul the units, and Amtrak’s satisfaction with the versatility of the HEP-equipped F40PH ultimately doomed the SDP40F. Amtrak was able to trade in the SDP40Fs to EMD as more F40PH units were acquired in the late 1970s. The last SDP40F was retired from Amtrak in the early 1980s.

ATSF SDF40-2:
In 1984, Santa Fe Railway traded lower-power locomotives to Amtrak for 18 SDP40Fs, horsepower-for-horsepower. The SDP40Fs were reconditioned in the railroad’s San Bernardino, California shops to the designation SDF40-2 for use as freight locomotives. Santa Fe replaced the hollow HTC bolsters with conventional HTC bolsters, converted the below-frame combination fuel/water tank to an all-fuel tank, removed the above-frame water tanks (replacing these with concrete ballast) and used the engines for nearly 15 years. They were also given front steps and platforms. Their noses were notched after a second maintenance shop visit in order to improve boarding access.

While this file was created specifically for the Athearn SDP40F and SDF40-2 locomotives the file could easily be used for many other 16cyl 645E3 equipped engines. Do keep in mind that this recording is of a Silenced Exhuast 16cyl 645E3 so the turbo is less pronounced.

This 16cyl 645E3 Turbo with Silenced Exhuast sound file would be appropriate for the following locomotives:

SD40-2W
GP40
GP40P
GP40P-2
SD40A
SD45T-2
GP40-2
GP40X

Please note:
This file contains a "Class Light" feature which allows for Cycling Aux4, Aux5, and Aux6 when using a 21MTC decoder. Assign the "Class Light" "Sound" to the function button of your choice and and be sure each Aux listed above is set to the "Dimmable Headlight" lighting effect.

As with all SELECT decoders there are up to 16 separate horns, 2 separate brake squeals and 2 bells included on this one sound profile! All changeable using CV48.

CV48=64 Bell 2 *Default*

Add values from above for total CV48 value.

Default CV48 Value = 67

0 - EMD Silenced Exhaust 16cyl 645E3
3 - Leslie SL-4T #3
64 - Bell 2

Total 0+3+64 = 67
