This is one that I have tried over the last winter. We are in race season now in Oz. It's a very basic get you going style of workout. From this workout, they direct you to Starting Strength. The principle to remember with weights for track is to concentrate on your lower body and core. Your upper body only really needs enough muscle to be able to do the lifts. Any more than that is excess weight.
Also don't forget to be able to translate the strength onto the bike. Over the winter, I did this workout (2 days), a trainer workout and 2 rides of about 50km each on the weekends to keep up fitness. Once I got back on the track bike in our spring, it took me about a month to feel a real improvement which I put down to training that strength to work on the bike.
Also don't forget, there's lots of good sprinters out there that don't even lift. Targetted bike training could be as good or better.
