  • Auto detect allows operation on DCC only or DCC and DC power. TCS decoders are almost transparent on DC making the engine act like a decoder isn't there. Brake on DC allows you to control the lights while the train is in a DC block.

  • Quiet Drive is active at all times which greatly reduces engine noise.

  • Dither provides rapid bursts of power to overcome resistance. You control both the power and frequency. See slow speeds unequalled in the industry.

Rule 17 headlight dimming can be set to occur when stopped, opposite the direction of travel, or both. You always have manual control. Button control allows you to pick the control buttons of your choice.

  • Factory Reset lets you change most of your choices back to their factory default values if you get into a situation you don't like.
