I believe that a total of 25 were made in 4 different subclasses. The very first engine in the class (the one that the MTH model depicts) ran on pantographs using AC power while all the remaining engines used 3rd rail DC power. It wasn't as successful as the DD1s that these were supposed to replace. Something related to poor weight distribution, the side rod design, and the long rigid wheelbase made it unsuitable for long and short distance running; they were taken out of service before the DD1s even though they were newer.
