I buy the 71 C ground temperature; ground temperatures can be 25-35 C hotter than the ambient air temperature, which is what gets recorded. This is also why rails buckle more than you'd expect: on a 40 C day, you're likely to see the rails heating up to 60-65 (as in, if you touch them, your finger will burn).

Ground temperatures are almost entirely responsible for the majority of the thermal energy/temperature put into the air, down at the surface.
