I haven't yet unpacked my BEDT 0-6-0T LC+ 2.0 switcher, but my conventional Lionel Reading 0-6-0T #1251 die-cast switcher (6-28613), made in 2004, has been running for years without any tracking problems on the Atlas O-54 curves and turnouts on my layout. I believe the new LC+ engine is made from the same tooling and is mechanically similar to the Reading version but, of course, there may be detail differences. This short video shows the Reading engine, which is listed for O-27, smoothly traversing the two O-54 switches on my layout. I hope that the new version will do the same but will watch things closely when I start to run it.
