Any fellow ABDLs into model trains?

Just like the title, does anyone else here have model trains? Me personally, I have a sizeable collection of both N scale and G scale. N scale is amazing: very space-friendly, tons of options for locomotives in steam and diesel, unlimited rolling stock, and so many ways to set it up to run, either temporarily, or to build a layout.

G scale (aka Garden Scale) is majestic in size, but extremely unfriendly to any space it occupies, because it absolutely dominates wherever it is. G scale can also be very temperamental depending on the locomotive/rolling stock combinations.

So, who else is into this? Any Lionel/O Scale or HO scale hobbyists here?
