Dark territory

Alright kiddo, let me explain dark territory to you in a way that you can understand. Dark territory is a term used in the world of trains. Trains have these big tracks that they run on, and some parts of those tracks don't have any signals or communication devices. Those parts are called "dark territory".

When a train enters a dark territory, the train operator has to slow down and be extra careful. They can't rely on any signals or devices to tell them if it's okay to go ahead or if there's another train coming. Instead, they have to rely on their own eyes and ears to make sure it's safe to proceed.

It's kind of like walking in the dark. When it's dark outside, you can't see what's in front of you very well, so you have to be careful not to run into things or trip over something on the ground. In the same way, train operators have to be super careful when they're in dark territory because they can't rely on anything other than themselves to keep themselves and their passengers safe.

So, that's what dark territory is, buddy. It's a part of the train tracks where there are no signals or communication devices, and train operators have to be very careful when they enter it.
