Good Day Gentlemen,
The market maybe saturated with SD70MAC’s but not prototypical SD70MAC’s. The MTH SD70MAC truck placement is incorrect and the K-Line and Lionel SD70MAC’s have an anemic fuel tank. I still think there is a market for the prototypically correct SD75M, SD75I, SD70MAC, and SD70M.
My thinking on production runs, I would say that 3rdRail is very capable of offering diesel locomotives from the past and modern day diesel locomotives all in the same time period. More diesel locomotive projects give Mr. Mann more leverage with the model production companies.
Respectfully,
Frank Swafford
