Quite simply one of the most detailed plastic models ever made. Haidair--known mostly for their brass models--attempted a few in plastic to test those waters, but the models were so well detailed that they didn't do well for the company given the amount of time they had to spend on them.
The model has both plastic and metal details (the fan grill is thin metal, the horns are made of actual brass) and an outstanding paint job. The model is DCC-ready with an 8-pin connector already installed.
The DF3 is a copy of a Soviet TE locomotive and uses a copy of an American Fairbanks-Morse engine. The DF and DF3 became some of the mainstays of China Rail operations in the 1960s. Although they were designed to be used in tandem pairs--as they mostly were in the Soviet Union--they were generally used in singles in China.
The blue model is a special edition--only one of 1,000!
Please note--this is a wonderful model--very heavy and responsive--but it is somewhat fragile given the nature of Haidar's relationship to making brass models. This is recommended for hobbyists 18 and over only. This model is new and only test run to ensure that it works and all parts are intact. Also note that Haidar does not ship any type of instructions with their locomotives. Removal of the shell involves taking off four screws on the bottom of the locomotive.
