Let’s do a quick recap first!
Now that you understand what ATMS is trying to do, scroll down to get a detailed look at how it works.
Don’t forget about your ATMS components table and the product specification document from last week, they will help you understand the next part.
The flow-chart below shows us how ATMS components interact with the rail infrastructure.
This flowchart demonstrates how the trackside infrastructure, NCC and train communicate with each other. It also shows us the type and direction (note the differences in arrowheads) of signals they use to communicate.
You may remember that currently, only certain parts of the train line use the ATMS. Here is a step by step of what happens when the train is entering and leaving the ATMS equipped region.
Perfect, now we can move onto designing the ATMS.
Since you’ve had a look at how the ATMS works, we now have to figure out what changes we need to make to the ATMS to account for train safety.
Here are the steps we need to take to do this.
