Default Why is the piccadilly line so slow?

Exactly. It may be close to Leicester Square station underground, but
Covent Garden station is nevertheless a busy station in its own right. And
the surface route between them isn't direct or obvious.


It looks pretty straight on Google maps along Cranbourn St and Long
Acre, but I don't think I have walked that way when I've been in
London.


Perhaps because of the talcum powder?

Joking apart, I've walked down there a hundred times, and that's without
ever having lived or worked in the vicinity.

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:

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".

How do you catch up if you're normally running at the 45mph limit for that section? In practice, if the service is running late, the westbound Picc trains often queue up to get into Acton Town. It's ironic that at a 4-platform station they manage to make it a bottleneck by changing drivers there and not always using the extra platform.

Northfields trains tend to use the westbound District platform 1; Rayners
Lane trains use 1 or 2; and Heathrow trains normally use 2.

Sep 2017, Recliner remarked:
I wonder why covent garden was spared? Its a small cramped station
that can't really cope with evening crowds and its literally a 3-4
minute walk to leicester square. Its a bit of an anomoly IMO.


IMO the explanation is lots of tourists, who support lots of shops and
restaurants, who pay lots of business rates, add up to a good case not
to make it harder for tourists to find Covent Garden (on the tube map)
and get there.

I suspect the opera house is more likely to be the reason. Covent Garden
was still a fruit market when the other Picc stations closed.

Not to mention the LT Museum — wouldn't it be embarrassing to close the
nearest station to it?

The museum opened in 1980, when were the closures of York Rd, Brompton
Rd etc?

Almost fifty years earlier I think.

I was suggesting that it survived the 1990s closures partly for that
reason. I dare say that there were suggestions to close it rather than
replacing the lifts.

Apart from Aldwych that closed for very different reasons, what others
were shuttered up in the 90's?


The Ongar branch closed on the same day as Aldwych. They could well have
closed Covent Garden on the same day, had there been a desire to do so.


The Ongar branch is the same kind of completely different closure as the
'Aldwych Branch'. There's no synergy whatsoever with closing just one
intermediate station on a line that's still operating fully.


The synergy is that they could have slipped it in to the closures list
had they really wanted to close it. But they didn't.

You'll need to cite rather more about the process of closures to make
that opinion stick.

Except in my experience they don't.

They manage that at arnos grove too. Its quite an achievement really to get
something so simple so arse about face. I guess they just let the clockwork
computer at earls court to do its thing and no one bothers to override it,
easier to just let the line block up and read The Sun.
