I keep em seperated... If anybody knows me they know my favorite loco is the MT Mogul. I think they look great...until they are next to an AZL mike. Then the cab suddenly looks HUGE! Funny, the bolier and everything else looks good but the cab suddenly looks chunky. I never thought that before. Running the two together just doesn't look good. If I run the moguls they run together or with MT diesels. I had this issue with the AZL GP 7 and the SD 40-2 from MT, it kinda looked like a bowa that just swallowed a goat. But those were just diesels. So it didn't matter to me then. Now I am not down on MT at all. The MT locomotives are very reliable and super runners and look great, as long as I keep them together. For instance the GP 35, GP 9, and SD 40 from MT look just fine together, but I can't throw in an AZL GP 30 or 7 without thinking how skinny they look. So I go in cycles and run locomotives in tandom based on manufacturer so they look right. (The GP 38 from AZL is kinda a twinner and looks good with both.) So I seperate, and with the mikes running well my moguls are not getting as much run time. I used to think the AZL gp 7 was the best runner, now I think it is the mike. They are loud but never, I mean never stutter or stall....and they look great. I don't want to take them off the rails. Now I am contemplating how I could cut the cab off of a MT mogul and replace the marklin motor with a coreless and maybe cut the cab off of a marklin mikado shell donner and create a loco that I can run with the AZL mikes that looks correct. Because right now I just can't do it. Anybody feel the same way?
