THis is the new offering from Searails. http://www.searails.com/locomotives/zemdmodel40switcher.html I have posted some videos on my Youtube channel https://www.youtube.com/user/MrGarthah I was impressed with this engine. It is a brass casting on a power max V2 chassis with directional lighting. It will run on the smallest of Rokuhan curved radii, on the flat I was able to pull reliably 7 Intermountain cars, which are mounted on AZL trucks with auto latch couplers, The Model 40 comes with Micro Trains 905 mounted at both ends. After seeing how many grain hoppers it would pull, I switched to Micro Trains cars and was able to reliably pull a mixed train of 10 cars with a caboose, again all these cars have had their wheel sets changed to metal wheels sets. I tested the engine with grain hoppers on 4% grade and was able to start and stop 4 cars on a grade with a curve (R220mm). all testing was done on ROkuhan roadbed track on my 2 x 6 ft test and show layout. David George also received one of these engines.
