Bachmann DF4 Locomotives
Important to China's freight and low-speed passenger lines, the DF4 series is the rough equivalent to the EMD 40 series of locomotives and the Soviet/Russian M62 series.
Please note that these are all "new old stock" (NOS) and have not been run except for testing purposes. However, because some of them have passed between several hands before reaching the Sensei, the boxes they are in will often show signs of shelf and handling wear. The Sensei knows his suppliers, who are either collectors or those involved with manufacturing, and can assure his customers that these have never been run on a layout in any measurable way.
