Hi, guys. I haven't been here for a long time due to the fact that I lost all my bookmarks and it's taken me quite a while to find you again. I forgot that there is a - in The-Gauge. The time is fast approaching for me to build my first ever railroad. As I mentioned, many moons ago, it will be a small mining operation of some sort. As my space is limited, I am considering narrow gauge. Therein lies my query. Are there any differences between HOn3 and HOn30?
