I have two of the 2-8-2 engines, one with TMCC and ERR Cruise added and another with LC+. I'd also rate them above average in detail for Traditional O engines. Nice looking, very good replicas of the original, just on the smaller side. Both are rated for 27" curves, so that tell you these are smaller even among Traditional O. The LC+ Berks rate for 31" curves, think.
Being pre TMCC and LC+, mine have 2 chuffs per revolution. The drive wheels are pretty small, so I'm not sure how good 4 chuffs will sound with LC+2. Might sound like a machine gun.
