Why is the piccadilly line so slow?

Why is it so slow and so unreliable with frequent train gaps of 5 or 6 minutes the rush hour? Trains? Drivers? Signalling? Dwell times? Stations too close together in the centre with too much stopping? All of the above? Here's an interesting article about how the Victoria line, with new automatic trains and signalling, achieves its very high frequency: https://www.londonreconnections.com/...aking-victoria frequent-metro-world/ Maybe, when the Piccadilly line also has state of the art trains and signalling, it will do the same. But it will still have a route with curvier tunnels and more stops than the much newer Victoria line, opened more than 60 years later. The picc only has sharp curves at holborn and kensington. The rest of the line is pretty straight with a long no stopping section between hammersmith and acton that should in theory allow drivers to catch up if they're running late. Not really. They're scheduled to run fast on that section anyway, and the old signalling doesn't allow them to run closer. Mostly they run slower than they theoretically could on that section because they're following another train. And they may slow down to a crawl towards Hammersmith or Acton Town as the platform is still occupied by the previous train (that happened to me yesterday). So there's little or no scope to catch up if "they're running late". |
