I have/had exactly what you are looking for. I used it on occasion, but never really liked it. once the computer track programs came out, i put it away somewhere, never to be used again. I haven't seen them for sale aywhere, either.
The computer programs are just so much better to use--- there are at least 4 programs i've used/tried in the past: Atlas's Right Track software(no longer available), Winrail (the parent of Right Track), Xtrak Cad, Anyrail, and the one I use now: RR-Track. For me, it's the best program out there.
Each program has it's supporters and detractors. you would have to read up on them, try the free versions(if they exist-- like Anyrail's), and see which one you like.
I just did a google search for the track template-- it's been discontinued, and is no longer available for purchase.
guess if one of us has one that is not "lost in space" they can send it to you if you insist on going old tech.
hope this helps--
