Hello.
My Father has a nice orchard and he has shipped everything from tomato's to peaches 1000km with Greyhound over to me.

You don't need to keep them cool.

All he did was wrap up the peaches in a good quality paper towel and then wrap it again in news-paper.
Line the box with crumpled news-paper and then in between the peaches. Cover the top with a thick layer of uncrumpled paper.
Some peaches will be sacrificed but on the whole most will survive.
