"After all, it's not as though the service on any tube line runs so precisely to the minute that a couple of minutes extra would ruin everyone's schedules."It would ruin LU's timetable because you'd need an extra train and driver to insert into the service to plug the gap that these extra couples of minutes are causing. It's actually about 70 seconds per journey, or 2 min 20 sec per round trip.You might argue, as I've done in the past, that the timetable is too slack and could be tightened up in order to create the time needed. LU would argue that with current passenger demand, reliability would suffer if they did that. And the limitations of the signalling around Turnham Green will always restrict the reliability of a 24tph service until the line is modernised.
