Re: gauge railway workshop to yard

Hello all
Yup really niche question this.
Friend re-concreting his workshop floor, and intends to lay
mine-railway tracks in it.  Which runs out into the yard and enables
machines which make a mess to be wheeled-out from stored safe and dry
in the workshop to working some distance away given associated dust
when running....
Anyone know of an argument to choose one gauge over another?
-------------------------------
After thinking about it more, I'd much rather have a level paved walkway wide enough to allow rotating machines for long stock clearance or putting cut marks in sunlight and letting one pass another, inside and out. Indoors machines on swivel casters can be pushed sideways against each other, like my welding equipment. My basement (cellar) is at ground level in front and I roll the equipment into the driveway to make sparks or sawdust. (Not "and")
Currently I'm cutting 6"x6"x16' oak beams that are difficult to maneuver even outside in the yard, around the house and up the hill into the woods to store them under cover. I suppose the best answer depends somewhat on the size/weight of his equipment (hammer-mill?) and what he makes, for me the longest steel assembly to be hoisted, drilled and handled is the 24' sawmill track. The heavyweight chip makers are the lathe and mill which are top heavy and spread sharp metal chips I don't really want scattered outdoors. "Mice" such as these are available to roll seriously heavy industrial machinery:

Heavy duty wheels of custom width can be made from large pipe tires and small pipe hubs, bored smooth and to size (after welding the spokes) for needle bearings cut from gas welding rod. I made stainless ones for the platform stacker that shares a damp dirt shed floor with the tractor.
A shop crane can become a self-loading trailer by putting planks to support the load across the legs and a trailer coupler on the mast end. Mine lifts 2000 Lbs and has larger added wheels to roll on dirt. One might be the simplest way to move the hammer mill or anything similar you might be tempted to acquire.
The peril of having narrow gauge tracks:
