• Will easily power HO-scale engines yet is small enough for many N-scale installations.
• X series features (click here for information on X series features)
• Adjustable Dimming  (click for more information on this )
• 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.
• Three point acceleration and deceleration  curves. Allows stretching of acceleration rates at the slow speeds. You are no longer limited to a straight line accel / decel rate.
• Quiet Drive is active at all times, which greatly reduces engine noise.
• Dither (digital pulse power) provides rapid bursts of power to overcome resistance. You control both the power and frequency. See slow speeds unequalled in the industry.
• Lighting Effects: Auto-reversing headlights, new improved Mars, Gyra, Prototypical Blinking Ditch Lights, Rotary Beacon, Opposite Dim, Single and Double Pulse Strobe, Rule 17,  Flashing and Random flicker. 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.
• 128 speed steps are active when Mid volts, Top volts, Start volts or the user- loadable speed table is active for much smoother operation.
• Primary 2-digit addressing or advanced 4-digit addressing may be used.
• Consist Addressing has a Special Feature allowing you to automatically turn off any undesired lighting when you add the engine to a consist.
• TCS decoders support all programming modes plus OPS mode ( on-track programming ) and meet NMRA DCC standards for compatibility.
