I would stay away from track spikes. If you put them in too tight, your track will go out of gauge, if you don't put them in hard enough, your trains will hit them! I use a latex contact cement. Paint it on the track and the roadbed. After an hour, it's dry and you can lay the track and it won't move. You can set it where you want, and if you don't push it down too hard, you can re-adjust it. Once it's where you want it, just press it down. If you want to take it up, all it takes is a Sharp utility knife. The ones with the long, replaceable blade. I've had my track down for about 3 1/2 years, and it has never moved, unless I have taken it up!
