Hi all,

I just got a Roco 4149A, already with center rail pickup for 3-rail systems, that I now want to digitize.
Apparently, there is no room for any decoder in the locomotive without machining some of the solid metal weights in the locomotive.

What would be the easiest way to put a decoder into the 4149A? Did Roco build replacement parts compatible with the old parts, but with room for decoders?
Or do I have to machine some space for the decoders into the existing metal parts?

Thanks
