The vast majority of London Tube strikes last exactly 24 to 48 hours. It’s like a very specific, very annoying public holiday that nobody asked for. They usually kick off at the start of a shift (say, midnight or 5 AM) and end at the same time the next day, or sometimes the day after that.
But here’s the kicker: the effects linger like a bad kebab. The trains don’t just magically reappear the second the strike ends. They need to be woken up, checked for gremlins, and driven to their starting points. So your actual suffering is often a two or three-day affair.
