Over the past couple of years AZL has stepped up and created much needed locomotives and rolling stock in Z scale. I am a somewhat passive Z scaler... but I have found myself buying as much Z scale as I do in my primary N scale interest. Most recently, the release of E7 units and lightweight passenger cars for the SP/RI Golden State... wow... really nice stuff. The 8000 gallon tank cars are awesome as well. We really need to get are some nice western versions of offset coupola cabooses in wood or steel variations for the end of our freight consists.
