I also can switch over to analogue ops. Here's the ?. I have some and are getting more digital Loks with sounds. Is there a way to connect a resistor to these signals so that the Loks lights/sounds will not go off at a red light? Where is the resistor placed? I operate signals using control boxes, not digitally. If these resistors work, how will they effect analogue ops? Thanks for your help. Peter

In the "old" digital days it was recommended to have a 1,5 kOhm resistor from the layout power to the isolated section so the decoders would not lose memory. However this is not enough to keep decoder functions working with modern decoders as I understand.

For decoders that support ABC braking (e.g. ESU LokSound 4) you can use diodes to achieve that. It's a general problem with new decoder features that many older locos do not support it. The Märklin braking modules have not much more than a diode. This is an older technique that will work with more decoders, but requires more parts. Also check Bogobit braking modules and others that implement the same technique. Just a resistor will not work.

A Braking Module allows the trains to slow down and stop at the end of the platform, with brakes squealing away merrily. The smoke and sound functions remain on while the train waits at the station. When the signal goes green again, then the train accelerates slowly away, choof .. choof .. choof .. it sounds so nice ! Have a look at my video attached : http://youtu.be/bMvqutoz1LU Regards, John
