The problem with some of these old lines is that they might have level crossings in which pedestrians or cars might occupy the tracks - so someone needs to be there to stop the train if that happens. Fully automated systems like the SkyTrain or Japan's Yurikamome line have grade-separated tracks (and in some cases platform gates as well) to ensure that sort of incursion doesn't happen.
