Alright, 17 minutes 11 seconds.
We were sitting at Richmond Station when the announcement suddenly came over that we were now going to travel fast right through to London Waterloo. This is that journey. My phone isn't great quality, but for this route to ignore Clapham Junction (Britain's busiest railway station!) does seem like a rare event. Also sped through are North Sheen, Mortlake, Barnes, Putney, Wandsworth Town, Queenstown Road and Vauxhall.
