I made up a little tool (well, it's about 2 feet long). It has a length of track, a Kadee height gauge and a rerailer. Along the side is one of the rulers that IKEA supplies, glued on as much as possible. And the NMRA weight formula.
I have a feeling that the weight formula was developed in the days of cast metal ends and very solid wood floors and roofs. It may need trimming down.
My second tool has something the same, but there's a hole under the track at one end with a bit of metal soldered across it. I use the tail of my vernier calipers to see how high the bottom of the car floor is above the rail. I bought a neat caliper on sale that is electronic and can switch among metric, decimal inches and fractional inches.
