Finally got this straight thanks to all of you.
Nice video and good little layout, Eamonn. Must be the sunny south-east to have it outside.
Thanks, David for your input.
Noel, is your center car the power car for your DMU? Have you triple headed anything with your DCC, it's NCE? If so, it's odd looking brown hose-pipes versus the cost of two lighting decoders one for each end car. Might be better in the long run?
One more question folks…
If I were to install something like Enniscorthyman's setup and later wished to have cab lighting for the cars and/or lighting for the passenger compartment, what would I need in terms of a decoder. I presume the TCS light decoder is good for maybe two functions (red and white marker nights, respectively). Do I need one to handle four functions (i.e.cab, and passenger comp lights)
