Tracker 2000 is a great little program that lets you design and build layouts for various types of tracking systems. The program will keep a running inventory of track pieces being used and will also calculate the distance of your track layout. This version of the program is a DEMO and is no longer supported by its creator. Tracker 2000 is offered as shareware only. I will not give out the registration codes , but if you do a quick google search for them they can be found rather easily !
