Moritz,

one of my next jobs will be adding led's to my Roco (Tillig) double decker coaches and I will be using my Märklin DB BR 143 to haul the coaches.
I make the led strip myself and with open interiors I use reflector strips and place the led's within. the other new option I've noticed with ESU Version 4 decoders you have an added light function (neon lights) I first seen it on a SBB ICN train and looked cool.
my interior lights are divided into 2 circuits (Aux 1 + Aux 2) and I use Roco 4 pin electrical couplings. I use the 4 pin as follow: Aux 1 (green wire) = Function 1, Aux 2 (violet wire) = Function 2, red wire = centre contact, bleu wire = common wire )Led's.
I configure the Aux 1 and Aux 2 in such a way, Aux 1 = random spots including the 2 toilets and marker light, Aux 2 = the rest of the random arrangements of led's in the carriage, I also miss some apartments and Aux 2 is mainly switched on when approaching a station.

Hi Ashley,
I'm not sure, if I would have done the conversion. I was very surprised last weekend, that my E60 doesn't pull much waggons. But maybe, I just have to change the rubbers.

But of course, the loco drives very smooth, very silent. On the other hand, because of the missing space, there is no flywheel mass possible, which would give more underrun.

I payed ~160€ incl. conversion and Esu LokPilot V4.0. I think it was worth the money.
