I spent seven years working from home, making a trip from my home to company-HQ every few weeks. The train information board would also say "Train Late: ETA $(current time + 1 minute)".
Even if they knew in advance it had to be 30+ minutes behind schedule it would always say something like "Time: 13:30, ETA: 13:32" or so. Then keep updating. It meant you never had any idea if the train would genuinely turn up in a minute, or if it would still be lying to you an hour later.
I did seem to suffer from bad luck on the days I travelled, due to land-slides, rain, wind, or power-failures on various parts of the line. I usually kept waiting, but some days you could tell there would be no useful service. (i.e. They'd offer buses instead of trains, and that meant a 2 hour trip down, a working day, and a 2 hour trip back was just written off because a bus might take 4-5 hours to make one leg of the journey.)
