Rail Atlas

Can someone provide me a retailer who sells a US rail atlas. I'm looking for a soft cover volume of relatively recent rail maps, maybe state by state, of major rail routes, preferably showing current Amtrak routes. I've searched hobby stores, Barnes Noble and Amazon. The closest I found is a wall map of US showing major railroads. Good, but looking for a travel size guide. Amtralk site has routes, but shows rudimentary maps with little detail. Thanks!
