Last week, we figured out how the ATMS interacts with the control centre and our trains. With our flowchart, we can see how ATMS components communicate with existing trackside infrastructure. Now we’re going to figure out how ATMS components (pre-existing and any that we create) will communicate with each other, the trackside and train infrastructure, and the Network Control Centre.
From this, we can assume that making something like the trackside interface unit - perhaps a tunnel access interface unit - in your ATMS would be a good way to connect everything inside the tunnel with the NCC and the driver.
Remember, however, that this is your design and you can design your ATMS however you want 👌
