Plywood comes it many different qualities. Have a look to the guys that build sailplanes with a plywood skeleton. They buy thin and light plywood as expensive as gold. I am afraid you got a quality not suitable for track base. May be you should go to a good shop and have a talk with a skilled sales person about their plywood qualities and suggested usage.
I did buy ones 3' long wood strips 1/3" * 1/3" at an home improvement center to support my buildings. It was a disaster. The cheep wood strips were everything but straight. I had to buy another set at the double price.
