More Info[1]

Overview

TCS Locomotive Works DCC sound-equipped U25C includes a TCS WOWSound® decoder with factory-preset prototypical sound configuration. This model also includes Keep-Alive® for uninterrupted operation, even over dirty track. The WOWSound® Diesel locomotive sound package includes sounds for horn, bell, prime mover, air compressor, cooling fan, coupler close/release, brakes, and many more! (See below)

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 true CD-quality audio (16-bit, 44,100Hz)
  • Authentic and prototypical sounds set by default
  • Over 50 horn and over 40 bell options
  • Keep-Alive® included, which keeps your engine running during power interruptions due to dirty track or loss of electrical contact
  • Directional headlights 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)
  • Two select-able Throttle Modes
  • Two configurable Momentum Modes
  • Die-cast frame

Additional Features

The U25C 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 Steam decoder.

Note: This WOWSound® product includes TCS' Audio Assist® auditory feedback program.

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.
