It would be a great idea if they compiled all the information of planned work on one wkend. Which they already kinda do, but make it specific to a certain train line by printing it out and handing it out to the conductors in the train yards. On the paper, it could say when approaching such and such stop, make this announcement so pax aren’t waiting on the platform for a nonexistent train. I find that sometimes conductors don’t even know what’s going on. I know some conductors already do this but it’s honestly hard to remember what’s happening to all the train lines at the same time.
