DT300 & DT400 Series Throttles

Digitrax Advanced throttles are different from most throttles you have ever used because they have two sets of throttle controls on a single hand held. The left hand throttle knob & the left hand direction arrow key work together to control the speed & direction of one train while the right hand side can control another train at the same time. This arrangement is particularly useful if you are operating alone & want to have two trains under your control. The dual throttle arrangement makes consisting & helper operations simple & much more prototypical.

The Advanced Throttle knobs themselves are radically different from anything you've probably ever used before. The throttle knobs are click encoders rather than potentiometers. What this means to you is that the throttle knob rotates more than one turn from 0 to full speed. The number of rotations is based on whether you have the system set up for 14, 28 or 128 speed step operation. Encoder Knobs give you incredibly fine speed control & when you select another loco, the throttle knob position does not change the speed of the new loco selected. No more rushing to adjust the throttle to match the loco's speed! You won't believe the slow speed performance! (Note: If you prefer pushbutton operation, you can use the up & down arrow keys to change the locomotive's speed.)

In addition, the throttle knobs can be used to select loco addresses to run and to reverse the direction of the loco controlled by the throttle.

  • A compact full featured walkaround handheld. DT300 & DT400 comes with infrared LED's and you just need to add a UR90 infrared receiver or a UR91 Universal IR/Radio receiver for low cost tetherless operation. Note: DT100's and DT200's cannot be converted to DT300.
  • Dual click encoder throttles offer the finest speed control available. The encoders can also be used to select loco addresses to run and to reverse the loco controlled by the throttle knob by double clicking the knob.
