For your info, this engine became available in March 2015.

I had my eye on this one since announced.
I am fortunate to have 2 KM-1 models of a similar freight engine in G Scale (1 gauge).
Think this was one of the largest freight engines in their roster (if not the largest).
I had noticed that there was some interest on this forum, last year, when announced.
