I played once and got all eight tracks - I'm quitting while I'm ahead!

wheeeeeeeeee! Thank you.

I've gotten more trains all out than I've gotten yard jams. Try to work on the right side of the screen because they don't block your rows. Don't move your locomotives too soon. Avoid mixing the same two colors on two rows--in other words, don't put yellow and green cars on two rows because you'll get all the rest out but those two colors.
