Here are a couple of links to the same video (one for Youtube and one for VIMEO - same video) of my start in G scale (gauge?) outdoor railroading.
It is VERY simple but I have found over the years that smaller IS better for beginners. I have been in and out of model railroading many times. At the present time I consider myself primarily a Z scaler but I also have On30, HO, HOn30 and N stuff - a real rubber gauger. I was an American Flyer kid growing up in the midwest. Since I still have those trains, I guess I am an S gauger too.
Enjoy and take it with a grain of salt as I play with trains to have fun.

Thanks for show the Centercab. I never know why the window was frosted until now… I was thinking it had something to do with hiding the motor drive. Now Look like I may have to get one and put in clear windows and detail. Tk’s. for the infro. Oh and nice video of how small of a trun it can do…
Yes, the frosting hides the interior. There was a vertical light post that placed the bulb at the height of the head lights. I removed that and used the wires to “reverse feed” the pick up to the motor. As it is set up now, this reverse feed also powers the track through the wheel pick ups - a bad idea for many reasons. No big deal right now but if I had another loco or two or a reversing loop, it would create problems. I will need to isolate things before I try to run it on anyone else’s track (powered or unpowered).
There are a few tricks to disassembly. I can’t remember the web site that showed me how to do it. One trick is that both headlights must be pulled out to release the roof. The “clips” that hold the motor block to the superstructure does take a bit of prying to “snap” out. Then you can disassemble by removing the newly exposed screws.
Lindley, Noel, or anyone contemplating disassembling a Mack.
Be VERY careful prying that clip holding the motor block in place, apply a bit to much pressure and it WILL shear off. I use a large flat screwdriver and apply just enough pressure so the clip just barely clears the tab in the block and comes out, more than that and I fear it will break. These weren’t designed for constant disassembly and reassembly.
Noel, I have several Mack bashes where I have removed the frosted glass and built full cab interiors, very doable.
Be very interesting to see what kind of toppings Lindley likes on his Pizza
