TG, the numbers are simply thickness in inches. For example, .030 is 3/100ths, or 30/1000ths of an inch thick. So, the smaller the number, the thinner the sheet. Bigger the number, thicker the sheet.
For comparisons, a typical hobby knife blade is around .025.
The rail of code 83 track is .083 tall - that's the rail only, not in combination with the ties.
