Hmm, I've had a totally positive experience running my brand new LC 2.O BDET 060 steam switcher on my Postwar tubular track layout with 022 switches and mostly 022 curves. No wobbles, no jerkiness in the way it runs, at various speeds using the LionChief App. I wonder if the type of layout impacts this engine's performance.
I have no advanced operating systems like Legacy and TMCC, and no modern track and switches like Gargraves, Atlas, Ross, etc.
It's also possible that I am not as particular about the operation of my locomotives as others on the Forum. For instance, I never run my engines at extremely slow speeds, but do run them reasonably slow to do yard switching. My BEDT switcher seems slow and smooth enough to do such switching.
IMO, the price (I paid $233 including tax), performance and appearance of this steam switcher could make it very popular in the O Gauge model train marketplace, but I'm no expert about such matters and could be wrong.
