It’s fixed now. See below.
The Jubilee Line of the London Underground runs from the north-west, through the centre, south-east, and on into east London. It doesn’t have any branches—well, apart from a secret spur near London Bridge, and a defunct one that used to lead to the old terminus at Charing Cross—so the only decision when getting on is whether to go towards Stanmore or Stratford, two stations whose names share the same first two letters, the same vowel sounds, and almost the same length, yet are at completely opposite ends of the line. Peering at a distant sign or hearing them over a fuzzy public address system, you might easily mistake them. Fortunately, all Underground platforms are also clearly marked with their compass direction, and announcements correspondingly mention the ‘eastbound service’ or whatever, so you can ignore the easily-confused names as long as you know vaguely which direction you’re going.
