Extensive computer experience or computer programming knowledge is not required. Almost all the territories in our "For Sale" and "Customer Contributed" libraries were developed by Track Builder 2 and 3 customers. Track Builder 3 also allows the user to modify any of the Train Dispatcher 2 and/or Train Dispatcher 3 territories in our libraries. You will need to purchase a territory password to run simulations on any "For Sale" territories you modify.
