Overview

Bachmann’s all-new DCC sound-equipped SC-44 Charger uses Siemens Mobility’s original design documentation and authentic sound files recorded from the prototype. This model includes a TCS WOWSound® decoder with Audio Assist® for easy configuration without programming CVs, and on-board Keep-Alive® device for uninterrupted operation, even over dirty track. The WOWSound® diesel-electric locomotive sound package includes sounds for horn, bell, prime mover, air compressor, dynamic brakes, cooling fan, coupler close/release, brake release and application, and many more!

Loaded with prototypical features, the SC-44 Charger in HO-scale from Bachmann Trains brings all the sights and sounds of Siemens' sleek new diesel-electric locomotive to your layout.

Features include:

  • Siemens-approved design
  • 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 true CD-quality audio with 16-bit depth resolution at 44,100Hz
  • Authentic and prototypical sounds
  • Voice-guided Audio Assist® programming tool for easy set-up of almost all decoder functionality
  • 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
  • Interior corridor work lights
  • Roof-mounted strobe lights, with operation per prototype
  • Directional marker lights
  • Steady/alternate flashing ditch lights
  • 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
  • Two configurable Momentum Modes
  • TCS' new and exclusive Function Pagination System
  • Die-cast frame
  • Separately-applied windshield wipers, grab irons and other detail parts
  • Realistic top speed (limited in some cases by track voltage)

Specific Features

The SC-44 charger is at its heart a WOWDiesel decoder but has had some customization to make it specific to the SC-44 Charger 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 SC-44 Charger locomotive will sit still until a sufficient track voltage is present. Once the minimum voltage is met the locomotive will begin to move. A horn blast and bell will activate automatically. 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 and are controlled by the Automatic Sounds CV.

Additional Sound Features

The SC-44 Charger locomotive features new sounds such as “Whoosh” and “station announcements” as well as new traction noises like “traction motor” and “traction motor gearbox." Listen for the whine of the traction motors as the prime mover spools up and the Charger takes off. As the locomotive climbs toward 125 MPH, the traction motors are drowned out as the noise from the gearbox hardware hums ever louder.

The SC-44 Charger supports an "automatic bell" in DCC mode. After the locomotive starts the bell will play until the DCC mode automatic bell cutout speed step is reached. Please refer to the CV Addendum (Indexed CV's) section below for more information.

The SC-44 Charger includes a brand new Emergency Brake air dump sound. This sound will play if a user presses the Emergency Stop button on their throttle, if the Brake button is pressed 5 times in a row, or if the decoder goes into emergency via the "Crew Alert" feature.

New Lighting Features

The SC-44 Charger features a fully-functional emergency strobe light that operates prototypically. Send your DCC system into emergency and the engine will immediately stop and turn on the red strobe. Additionally you can also activate the “emergency brake” manually by engaging the TCS-exclusive Braking Feature fully with five rapid presses, after which the train will come to a quick stop and turn on the strobe.

The emergency strobe light also works in conjunction with the “crew alert” feature. The crew alert feature acts as a “dead mans” switch. If no user input is received after a set amount of time the alarm will sound giving the user short amount of time to enter input or else the train will go into emergency, brake, and come to a stop with the red emergency strobe flashing! When the crew alert feature is enabled, the emergency strobe will activate once the crew alert timer expires.

According to § 1.4.12 of the Siemens SC-44 Charger Operations Manual, the strobe lights function automatically when certain conditions are met. The white strobes will flash when the ditch lights are activated and headlights are at full brightness. TCS has implemented automatic and manual control modes for the white strobe lights. The factory default is set to automatic control (CV182 bit 7 is ON). In automatic mode the white strobe lights will behave as described in the Siemens manual section 1.4.12 while the strobe button is activated on the throttle (default Function 5). When Function 5 is activated, the strobe lights will turn on when both the headlight and ditch lights are active. If Function 5 is turned off, the strobe light will remain off regardless of current head and ditch light states. In manual control mode (CV182 bit 7 is OFF), headlight and ditch light status has no effect on the white strobes. The white strobe lights are controlled manually by the throttle button.

Button Mappings

The values outlined below in the button mapping, sound list, and CV values are the defaults assigned to this particular decoder from the factory.

For information on how to program your locomotive using the values provided in the charts below, please see our Comprehensive Programming Guide, WOWDiesel V4 Programming Guide, and/or List of Standard CV's.

TCS Function Pagination System

The Bachmann Spectrum SC-44 (Charger) - N locomotive supports TCS' new "function pagination" system. This makes it easy to access all 28 functions and all lighting effects on throttles with limited function access by adding an offset to the pressed function button (offset of +10 for function page 2; offset of +20 for function page 3). For example, to access function 15:

  • Press function 8 twice to rotate through the function pages until the decoder announces "function page [two]"
  • Press button 5 on your throttle/controller
  • The decoder will activate function 5 + 10 (page 2 offset) = 15

Note: the decoder supports accessing functions above 9 at any time by pressing the corresponding button(s) on your throttle regardless of the currently selected function page.

If you have a command station which supports all 28 function buttons and would like to disable function pagination, this may be done by re-configuring the User Options indexed CV 4:19. For more information on the User Options indexed CV for Version 4 WOWSound Diesel decoders, please see Page 19 of the WOWSound Diesel Version 4 Complete Programming Guide. This document can be used in conjunction with the Indexed CV Addendum below.

To disable Function Pagination, you must first have a Charger decoder with a manufactured date which falls within or after the Second Run (After January 18th 2021). First Run Charger decoders do not support the option to disable Function Pagination. Set the values of the Indexed CV as follows:

  • CV 201 = 4
  • CV 202 = 19
  • CV 203 = 144
  • CV 204 = 251

Speed step at which the decoder will begin playing the High-Pressure Horn. When the speed is set to below this value, the decoder will use the low-pressure horn. A value of 0 disables this feature, and the high horn will always play. A value of 1 will only play the low horn when stationary.

(Valid Values = 0-126)

NOTE: This feature only applies to specific horns, and does not apply to all horn sets available on this decoder.
