This causes the locomotive lights to go out. Is there a way to stop the train while maintaining the headlights? Thanks! Steven Delhaas

With the signals, I think you can add a resistor into the circuit which allows limited power to the stop section to keep the lights on. But, not having used the Marklin signals, I'm not 100% sure on that. You certainly can do it with other types of stop modules.

Use the braking modules #72441 or #72442 or similar modules (e.g. from Bogobit). The resistor trick will work with some new models with white LEDs, but light bulbs will not shine and motor sound will be off. Resistors were used with 6090 and older decoders to keep the memory alive. They were not used to keep lights on.

In regards to the 76xxx series signals, the only reference to resistors I can find is "If you have had problems with locomotives not leaving a signal block or leaving it in the wrong direction, you can solve this problem in the Digital system by installing a 1.5 kilo ohm resistor. This resistor comes with the k83 decoder. lt is also available from Marklin under spare parts number 517050."

Tom might be right,it has not been tested here. I have used headlights on,to know the lok is called up on the CU,although there are some rules if lights are on during daytime and what the operations are,... Dr D
