GSM-R
GSM-R is like a special phone for people who work on trains. It helps them talk to each other and stay safe while they are doing their work. It works kind of like a walkie-talkie, but is more advanced.
GSM-R uses a special type of network to communicate. This network is only for trains and train workers, so no one else can use it. It also has extra features to help train workers stay safe, like emergency buttons they can press if something goes wrong.
So next time you see a train worker using a special-looking phone, you'll know that they are using GSM-R to stay connected and safe on the job!
