This Video introduces the LoDi Digital control System explaining the different parts from driving, switching and track feedback (detection). Their digital system has been designed for larger layouts and works fully with Railcom. The system also has massive benefits if you are running iTrain. There are loads of extras you will see in iTrain, such as the current draw in each block and short circuit protection monitoring, in each block. iTrain will then show display exactly where the short is.
