First time poster. Please accept my apologies if this has been asked before, but I couldn't find any post when I searched the forums. I have a couple questions.
1. What is the difference between the Vision Line Genset Switchers (UP & NS) released in 2009 and 2010 and the recent legacy switchers released by Lionel in 2013, 2014, 2015? Is the three operating smoke stacks the only difference at this point?
2. What is the difference between the Vision Line Canadian Pacific ES44AC released in 2010 and the ES44AC's released in 2014-15?
3. Same question for the Vision Line GE Evolution from 2009 and Lionel's recent releases?
Steam engines comparisons are much easier for me to figure out through my research, but I am having a difficult time understanding the differences in the diesel locomotives. I appreciate any information you could provide in answering these questions, and I thank each of you in advance for your time.
Chris.
