A true plug n play installation! Please read technical note below.


Technical note: This loco uses 4 light bulbs in parallel in the front. They are connected to function zero (headlight) of the decoder. Older DP2X (formerly TH150DP) decoders could not handle the power needed for lighting all four bulbs at once. However all DP2X decoders shipping since the fall of 2004 have the power ability to power all four bulbs. If you try a DP2X decoder in this unit and the lights do not work please return the decoder to TCS for repair/upgrade. This service is covered under warranty. Should you need to return a DP2X decoder, please use a small box to avoid damage to the decoder.
