This article was last updated on Jan. 9, 2012, 5:03 p.m. | Print Article | Leave Feedback

The DT400 series’ Track Power Indicator and the DB150’s track status indicator show whether track power is on or off.

The first time you plug in your DT400 series throttle, track power will usually be off.

To run trains, you will need to turn on the track power. Look at your DB150 and/or DT400 series to determine whether the track power is on or off.

1. When track power is off:


  • DB150 TRACK STATUS indicator is off
  • DB150 OFF LINE indicator is on
  • and DT400 series Track Power Indicator is off (Track Power Indicator is a small dot in the top line on the right side of the LCD of DT400 series)

2. When track power is on:

  • DB150 TRACK STATUS indicator is lit
  • DB150 OFF LINE indicator is off
  • and DT400 series Track Power Indicator is on (small dot in the top line on the right side of the DT400 series LCD)
