Trix Express 20/60 E94 007 Automatic AC (kds32) was only offered from 1951-55, as the drive and clutch function only worked in the AC system via shift drums. So the locomotive was no longer offered after the operating power change from the factory to DC. Of course there is a new grinding set.
This probably unique wonder of precision mechanics was called "locomotive of a thousand parts" among model train engineers!
The locomotive was released in April 2015 by E94 specialist Hr. Nowack technically completely overhauled it were exchanged (as always by zinc break disintegrated) Kupplungsausheber against replacements. Of course, the report about the executed works is enclosed, from very well-kept collection, technically top and optically very well preserved in the original wooden box, see pictures.
