At the Internationale Spielwarenmesse 2014 Nürnberg (Nuremberg International Toy Show), Arnold displayed a preproduction sample of their upcoming U25C diesel locomotive.  The photos below were shared via the Arnold Modelleisenbahnen Facebook page.

Of note is the glimpse of the new “ProtoMate Kupplung”, a new coupler design by Charlie Vlk being manufactured by Arnold and planned to be included on the new U25C.  Now, NZT Products was also planning on using the PROTOMATE name, and has preliminary trademark protections in place for the name.  We’ll be watching the name game with interest as these two new couplers come to market.
