I know based on pictures 3rd rail makes locos with detail that severely outclasses the majors. I also understand they tend to make everything much more prototypically correct.
I am interested though in how they perform overall? Are they cantankerous and require a lot of attention, or are they generally smooth runners with little to no issue?
It seems lately that Lionel has closed the price gap with most of their offerings at or near what 3rd rail prices are. MTH seems to still have a good price gap. So what's the trade off (if there is one)?
There are some specific 3rd rail locos I would really like, I just want to know the good, bad, and ugly up front. What to look out for if buying used and what models if any would you avoid.
Initially I am contemplating an AC9. Don't have the funds yet, but should before too long.
