Hi,

This is the new V60 chassis. It was available with the "old" telex as reference numbers 37615, 37655, etc. There were some more, but I don't remember them off the top of my head. Since these locos are the same as your 37695 for the most part, it may be possible to buy the parts and covert the loco to "old" telex. I can send you some pictures of 37615/37655 if that would help. I am not 100% sure if this can be done or not, maybe other forum members know.

You could also replace the new telex couplers with relex couplers in the NEM pockets. However, you would loose telex, so I don't think this is what you are after.

On carriages with NEM sockets for couplers, changing them is easy. Just pinch the end of the old coupler and pull it out, then pop a new one in. With older carriages without NEM this will be harder, I don't know if there is a really easy way that doesn't require some customization. You could also consider just having a few close coupler carriages and just use them as a buffer between your loco and the relex equipped carriages.

I ended up with different shunters with both kind of couplers, mostly matching them with "sets" of carriages. The old style telex work OK with close couplers in my experience.

With Märklin 7205 you can get close coupler heads (without guiding mechanism) for many cars that already have plastic couplers.
