Thank you for this answer.
1) Battery nope.
2) Availability is a key issue, Its easier to purchase companies you already deal with.. If that makes sense. I will ask my dealer about stainless.
3) Do you have a link to the US restaurant posts?
4) I clean the frack around every 3 months. Using a electrical contact cleaner, cloth. and shop vac. As you can imagine at that height its lots of fun

I'm finding it very hard to estimate the specific radius track pieces as the layout is fixed to a metal frame and can't be changed.
This is back ground information.
The shape is basically a compressed bone shape.
Both radii are close to 2m
The full track length is 28-29m
The estimate for curved track is:
32 x radius 3.
6 x radius 2.
Long straight 4.4m.
Short Straight 2.5m
Three pair of track connectors.
Some form of sound proofing.
