This is one of the reasons I often appear guilty of overpacking - I want to be able to be okay for an hour or two not moving while waiting for help.
In the era when I did a lot of rides that had long train returns, I often ended pulling out a lot of that stuff and putting it on, either while waiting for the train, or (for the lesser degree I carry in summer) surviving the train car's oppressive air conditioning while my post-exercise body largely shuts down. A knit hat is a big part of it. For the train returns I'd also duck into the restroom once we were rolling and replace wet kit with dry stuff, all the way down to skin.
