I picked up my 4014 LC+ 2.0 Big Boy a few months ago and it hasn't left the tracks since then. I had a few concerns when I took it out of the box, basically the front drivers were hanging off and I found the mounting screw in the box. I was able to get it reattached and I also had to tighten the nuts on the rods.
Since then this engine has given me nothing but joy. The sounds are incredible and Lionel did a great job on the details. If this is the future of LC+ 2.0 then I'm on board.
