I finally got started today…
I’ll leave you fellers to try to puzzle out where I’m going with this pile of miscellaneous crap.
I,ll take a stab at it. Some kind of car to measure levelness or grade?
partly… but it will do a LOT more
I’m thinking some type of NASCAR knockoff.
Seeing how Mik builds, it’ll probably turn into a locomotive!

OK, I admit, this thing looks REALLY, REAALLLY goofy… BUT As you push it along the track with a single finger, it checks for: level, cross level, dead power spots, high wing and closing rails, stones in the flangeway, mis-alignments and other in-gauge obstructions, locates small twists and dips, and verifies all proper clearances… What more could you ask for? No, it doesn’t make toast. Sorry. Perpendicular levels and a simple GoW bulb wired to one axle. The car is built very light so it will derail if there’s anything obstructing the flangeway.

It has a rigid 4 wheel suspension, if it rocks you have a dip or high spot. One end has the exact same width and overhang as my c-16’s pilot plow. The other end has the wheelset nearly flush with the end of the car, and has a drag bar that skims just above the rail head to help detect obstructions.

Mine, it just lifts off when not needed

Maybe I need to tart it up a bit and market it? lol
Now that’s one ‘multi-purpose’ MOW car. Something like WD40, supposed to fix everything.
Great concept Mik
Mik, Now you need to add the odometer so it can measure distance as well.
