==Overview==
The new DCC sound-equipped {{PAGENAME}} locomotive uses original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with factory-preset configuration and on-board Keep-Alive® device for uninterrupted operation over dirty track. The WOWSound® gas-mechanical locomotive sound package includes sounds for horn, bell, prime mover, air compressor, cooling fan, coupler close/release, brake release/application, and many more!

Loaded with prototypical features, the {{PAGENAME}} locomotive from Bachmann Trains brings all the sights, sounds, and character of a Davenport switcher to your layout.

==Specific Features==
Features include:

*DCC sound-equipped for sound, speed, direction, and lighting control
*Dual-mode NMRA-compliant decoder operates sound, motor, and lights on DCC or DC power.
*TCS high-quality 16-bit audio
*Authentic and prototypical sounds
*3 hand-picked prototypical horn options and 6 bell options
*On-board Keep-Alive® device that keeps your engine running during power interruptions due to dirty track or loss of electrical contact
*Directional headlights with "Rule 17" dimming operation enabled by default
*TCS' industry-leading "quiet drive" Back EMF motor control for superior slow-speed performance and load compensation
*User-loadable speed table options (3-point, 28-point, and 126-point curves)
*Three select-able [[Throttle Modes|Throttle Modes]]
*Two configurable [[Diesel Version 5:Momentum Function|Momentum Modes]]
*TCS' exclusive Function Pagination System
*Die-cast frame

==Specific Features==
The {{PAGENAME}} is at its heart a WOWDiesel decoder but has had some customization to make it specific to the locomotive. The information below details where CV’s and operation differ from the standard Diesel decoder.

'''DC mode operation'''

When operating in DC mode, the locomotive will sit still and silent until a sufficient track voltage is present. Once the minimum voltage (approximately 8 volts) is met, the locomotive will ignite the prime mover and the lights will come on. An additional increase in voltage will cause the locomotive to begin to move. A directional horn blast will sound, and the bell will activate automatically. Increasing the voltage further will shut off the automatic bell. Users may trigger a grade crossing horn quill sound by quickly adjusting the track voltage up and back down quickly. The directional horn blasts, quill, and automatic DC mode bell are enabled by default. If you would like to change these settings, as well as other behavior of your locomotive on DC power, please read more in our section on [[Diesel Version 5:DC Mode Operation|DC Mode Operation and Configuration for WOWSound Version 5]].

Note: This WOWSound® product does not support TCS' Audio Assist® auditory feedback program.
