Notes for the NJ Transit Arrow III

The GE Arrow III is an electric multiple-unit operated by New Jersey Transit. Open NEC equips the Arrow with universal cab signaling, ATC, and ACSES.

Mod compatibility

The Open NEC mod for the Arrow is fully compatible and tested with Fan Railer's physics and sound mod.

New features

  • Press Ctrl+D to disable and enable ATC, and Ctrl+F to disable and enable ACSES. Both systems are turned on by default.
  • In addition to ATC and ACSES, an alerter has been installed.
  • AI trains now run with their lights lit properly.


  • The Arrow's ADU works a little differently compared to the ones present in other NJT locomotives. Dovetail Games did not program the green speed bar correctly; they set it to track the current speed, and this cannot be easily overridden by a mod. Open NEC therefore uses the red speed bar to show the maximum ATC/ACSES authorized speed.
