Backdrop notwithstanding, what really caught my attention was the shrieking chuffing sound of the HO locomotive. It prompted me to look at others, so on YouTube I found an Athearn, an MTH, and a Rivarossi loco. Honestly, when compared to our Lionel and MTH O-Gauge sounds, the HO's sound sick. I am so glad I 'switched' to O-Gauge
