LGB is gone and they aren't coming back. Not the LGB of Germany that is. All LGB now will be either Hungarian or Chinese made. I don't see much of any American outline being released by LGB/ Marklin. Most all LGB was of a weird scale as in all over the place.
For great looking and operating large scale 1:29 trains seek out USA Train or Accucraft/ AML.
The best large scale trains are the 1:32 line made by MTH as have PS2/3, great detail and the ONLY large scale manufacturer to use metal gears throughout the entire locomotive lineup.
