I've seen specs for the F-3 as having a minimum radius of somewhere between 250 to 275 feet (depending on publication). 250 feet scales to 62.5 inches, 275 feet becomes 68.75 inches. So 2-railers aiming for 60-inch minimum radius are not too off from prototypical minimum (at least for an F-3). Our SoCal favorite steamer SF 3751 (4-8-4) can handle 360 foot radius, which scales to 90-inch radius.

I remember when Atlas expanded their line of 2-rail track to 54-inch radius, I was hoping they'd go a notch or two farther to 58.5 then 63. Guess the sales of 49.5 and 54 didn't support expansion.
