Kato N scale Daylight running in the desert on ATSF_Arizona's N scale layout
Kato F7 with a Digitrax decoder in it. Digitrax site says they make a decoder for the Kato F3... no mention of the F7.
If you see a difference, your eyes are better than mine.
N Scale Kato SD40 ATSF #5003. My favourite shelf-queen, because she'll derail on any flextrack curve I lay.
These are some recent acquisitions awaiting some minor tweaking before they are repackaged and put away in storage until the layout is complete....
