experiance with storing trains in the attic
I didn't store mine - I ran them. We dry-walled the attic and I got to use it as a train room.
It was outside the a/c area, but when the guys did the walls, they installed 'troughs' of expanded plastic under the insulation, against the roof, between the rafters. These provided an air channel from the soffit behind the gutter to the airspace at the top which was vented by the usual end gable vents. I was astounded how cool it was, even in a NJ summer.
So my suggestion would be to put some insulation between the rafters and fit these air circulation channels behind the insulation. Good vents should help. A fan to the outside with a thermostat that turns on when it gets hot should keeps things even cooler.
