Figures are "the number of passengers using the OSI over a four week period divided by 28", which isn't the best approximation, but should still give the correct ranking.

The 'naughty' non-OSIs. What is the reason for them not being OSIs when there appear to be more absurd (distance wise, convenience) exchanges that are?

TomH | 06.06.19 - 7:40 a.m. | #

So, clearly the OSIs that work (and are best understood by users) are where the two stations have the same name.
Honourable exceptions to this rule are in Walthamstow and New Cross.

I bet the majority of Lancaster Gate / Paddington isn't counted, because it is a transition between National Rail and Underground.

I wish they'd stick the distances on (in metres) for each OSI,

I'm kind of curious to know what really is the fastest way from Bank to Paddington. I'm a reasonably fast walker, so I tend to use Central line to Lancaster Gate and walk. But the obvious other options are walk to Moorgate (or Northern Line there) and Circle/H&C (presumably this would work out worse due to the somewhat reduced frequency of those lines), or Central then Bakerloo, or even Central to Notting Hill Gate then Circle/District.

I have a suspicion that come Crossrail the best option will be walk to Moorgate then Crossrail (I think the Moorgate end of the station will be slightly closer to Bank than the Liverpool Street end).

@confused - yes, i'm assuming many of hordes you see tramping this route are NOT using Oyster for their whole journey, so excluded from this data set

@Muzer - there's also the quality of life question! i would go for an airconditioned Circle/H&C train during the summer!

As one example, I can't imagine many people needing to interchange between Swiss Cottage and South Hampstead (there are easier ways of accessing the Jubilee Line), but it's weird for TfL to highlight it on the map and not include it as an OSI

It's patently absurd that the Bayswater/Queensway connection isn't mentioned. They are only a few seconds away from each other.

daveid76 | 06.06.19 - 10:42 a.m. | #

No, it would be patently absurd if the Bayswater/Queensway connection was mentioned, because (as the data shows) it's hardly used.

Is Fenchurch Street/Tower Hill an OSI?

Why would anyone use Bayswater/Queensway though? It'd only need to be used if you were going westbound Central -> eastbound Circle/District (or vice versa), and you have a perfectly good Lancaster Gate/Paddington or Bakerloo via Oxford Circus for any plausible journey you might want to make...

the orange one | 06.06.19 - 10:56 a.m. | #

I actually did the walk from Queensway to Bayswater back in Feburary just for the sake of it

The dotted line (described in the key as "Under a 10 minute walk") between Swiss Cottage and South Hampstead is the cartographic equivalent of the old "If I was trying to get there I wouldn't start from here" joke. If you were standing near S Hampstead station and wanted to go to Neasden (yes, I know!), without the dotted line you'd potentially take a really convoluted route, but seeing the dotted line you'd walk to Swiss Cottage and be in Neasden in 25 minutes.
I'd be surprised though if anyone can find a journey for which changing trains between the two stations is genuinely better than any alternative route, particularly with such an infrequent service out of Euston.

I've asked before.
Why isn't Leytonstone (Central line) / Leytonstone High Road (Overground)included?

dg writes: Twice before.

From Bank to Paddington, maybe walking to Moorgate is quickest - although you have to factor in that only half the trains from Moorgate go to Paddington, and they take you to the wrong end for the ticket office and other facilities. But having spent most of my career working at Central Line stations between St Pauls and TCR, Lancaster Gate is definitely the preferred option over changing at Oxford Circus and taking the infrequent and circuitous Bakerloo Line.

In general, links within Zone 1 are not shown as the map would be too cluttered.

Why do people keep going on about Bayswater/Queensway when exactly the same applies to Great Portland Street/Regents Park. Its not all about short distances between stations, but how useful the interchange is.

kev | 07.06.19 - 1:49 a.m. | #

I have used the South Hampstead/Swiss Cottage connection when the service between Camden Road and Willesden Junction was diverted via South Hampstead and the OSI was a useful way of getting to West Hampstead.

timbo | 07.06.19 - 8:12 a.m. | #

Only just seen this. Leytonstone to Leytonstone High Road should be shown on the map as Google puts it as an 8 minute walk. Ickenham to West Ruislip is the 2nd longest OSI at 0.7m and is there because the paucity of bus services in that area make it worthwhile. Finally, the longest OSI at 0.8m is actually Marylebone NR to Paddington NR (not LU). They wouldn't put an OSI for the LU station as it's two stops on the Bakerloo.
