Hello,
I purchased one of the Roco 45836 with taillights. The lighting is controlled by the polarity reversal (DC) and may have a decoder for operation in DCC.
Has anybody converted this coach or one of the similarly equipped DB or OBB coaches from DC to AC?
What would I have to do to convert this coach to AC (Digital Motorola)?
Regards
Mike C

I would think that a locPilot would work, since it is Motorola and DCC, the DCC plug might even plug into the Coach, Just need a pick up shoe and some rewiring.

the number does'nt come up on the Roco website. My connections are through electrical couplings including interior and taillights. As mentioned get a function decoder and connect it to the Wheelaxle (AC) and a pickup shoe. Some Roco coach bogies have the ability to attach a pickup shoe. This depends what type of coach you have. If my memory serves me right, coaches with metal bogy housing have this accessibility. In any case you would have to dismantle the coach and find out whats'cooking inside. regards., John |

For those who don't know, Maerklin released a series of models with built in DCC function decoder and LED taillights. I believe the models were as follows:
45834 DB Bpmz291 Blue/Beige
45835 OBB UIC-Z Bmz Red/White
45836 SBB Bpm EC
There was also a set of DBAG EC/IC Coaches in the ICE livery that had digitally controlled lighting and might also have LED taillights on one coach.
Specifically, these models come with special current collectors that are attached to the normal bogies. The axles are insulated.
I have no experience with decoders other than Motorola/ESU. I am pretty sure that this type of decoder will not function with AC or AC Digital.
I would likely have to replace the decoder with a Motorola compatible function decoder.
As an alternative, can I operate the decoder using an internal power supply such as Rapido Trains Easy-Peazy Lighting System or some kind of battery with a switch?
In normal DC operation, the lights are on in one direction and go off when the polarity is reversed. In digital (DCC) use, this is controlled by the decoder.
For operation in AC, you would need a decoder, even to switch off the lights when travelling in the reverse direction, as there is no switch, like in the pilot coaches to reverse the contact.
If I did go with an internal power source, how would I get the coach to detech the direction change and switch the lights off in reverse?
