I expect most people would just take a cab/Uber or drive themselves if the weather was inclement.
Yes, but I can't recite the specs from memory. Should be findable easily enough. The 510 dates from the early days when Trek sold framesets and the bike kits to make them complete bicycles. The 510 was the Ishiwata tubing in sport-touring geometry. The 530 was the same tubing (probably exactly the same main triangle, not sure) with shorter stays and a different fork for racing geometry. The 520 came later as a complete bike and while the earlier ones were sport-touring they quickly evolved into touring-specific bikes with cantilevers, braze-ons and geometry to match, such as much longer chainstays. My wife had an early taupe 520 that still used caliper brakes and had an SR triple crank that was a Stronglight 99 copy, but the bike overall was more sporty looking than tour-y.
