I notice on some train services during the announements it says "If you see anything suspicious, please report it to a train manager or a police officer.". Are there actually police officers on these trains, and if so so where are they located? Because the announcer doesn't say in which carriage they are located. So if anyone does see anything suspicious and they're on an 8 carriage train, how are they supposed to know where to find these police officers? Just wondering that's all. Never seen anything suspicious myself.
