Bachmann cleaned up their act when they introduced the Spectrum line now....25 years ago, maybe more? (I joined the hobby in January 2005 and their Spectrum line was well established by then.) I read posts by well-seasoned hobbyists early when I joined, one of them in a hobby shop in his youth (he was about 45 in 2005), and he used Spectrum steamers almost exclusively. He would bash them and re-decal them to suit his railroad, and was very good and convincing. He swears by Spectrum class steamers. Then, maybe 2012 or thereabouts, Bachmann simply produced only Spectrum class steamers, but didn't call them that. It was like it was meant to become the mainstay locomotives from then on. I have a Spectrum 'heavy mountain' produced somewhere near 2010 that I purchased on his say-so, and can't say I am disappointed. The one comment that seems common is that they, of all current steamers, seem to want a break-in, running them forwards and backwards around one's loop for a couple of hours. I found that, while my other steamers seem to need maybe a setting of 3-10 in CV2 (V-Start), a cold Bachmann Spectrum steamer will need at least 40 set to the CV in order to get the mechanism to begin to turn the drivers at Speed Step 1. Once it has run for five minutes, I can reduce that CV2 setting to 35 and get the same performance. So, a cold mechanism needs more voltage, or does in my particular Spectrum heavy mountain 4-8-2. My Spectrum N&W Class J 4-8-2 needed almost as much, but it had a wobble and hitch in its giddyup. I sold it.
