Circle Line - Why so slow?

Shame what are you doing in the circle line. Why not try something else.

they are all against you, and you alone. watch for it in other areas of our life, and you'll see it. i too get the circle line, and have no idea.

its one of the oldest and most dirtiest trains that u could ever have in london underground. tracks are always troublesome, the traffic is too much and commuters are too many. the only good lines that i have noticed are: Metropolitan, Jubilee(the BEST), piccadilly and the new District line Waterloo&city line, DLR and Northern line. the rest are filthy enough: Hammersmith&city, Bakerloo(the WORST), victoria and central line....most of them are good anyway....upgrades are always going on to these trains anyway , becoz there are people who feel like you as well, inclusing myself. check out for important news on upgrades for these lines all times..ull soon enjoy Circle line...don't worry....u can go round in circles.. saying froma decade of the London underground's experience..

That guy above me has pretty much wrapped it up, I was going to say that the tracks it runs on are the oldest in the network.

because between king's cross and edgware rd it shares track

may be because it goes roung in a circle, the train tracks are not straight so the train needs to slow down very often.
