Time to update some OSIs?

Hi all, first time poster. Nice to e-meet you all.

Maybe this is well trodden ground on the forum, but isn't it time TfL updated the out of station interchanges? The list on their website seems long, but it seems to be missing some obvious ones.

For instance, South Hampstead to Swiss Cottage is even shown in the official tube map with a dotted line connecting the stations, but this isn't an official OSI. Surely some unsuspecting tourists have come a cropper following this interchange and being charged for two separate journeys?

Another mysterious omission is the lack of interchanges between stations in Ealing. For example, North Ealing on the Piccadilly Line could provide a useful interchange with the Elizabeth Line at Ealing Broadway. On the map, this looks about the same distance as the nearby Park Royal to Hanger Lane OSI, but seems far more useful. Additionally, North Ealing to North Acton (for Central Line) seems very short indeed, yet no OSI!

It seems to me that recent Overline changes, as well as the Elizabeth Line, have changed the interchange landscape somewhat. Isn't it time Tfl had another look?

The list of OSIs does get updated periodically but I agree that it should include, as a minimum, all plausible interchanges that are within a 10 minute walk - and certainly those shown with a dotted line on the Tube map.

That said, there can't be many journeys for which a theoretical South Hampstead to Swiss Cottage OSI would be faster.

And there would be even fewer where North Ealing to Ealing Broadway would make sense. Surely you'd just stay on one station further to Ealing Common (if coming from the north) and change there for the District line to Ealing Broadway? Admittedly not much quicker than walking, but how many people make journeys like Rayners Lane to West Ealing in the first place?

North Ealing to West Acton (I presume that's what you meant) I can see slightly more logic for as it's a fairly short OSI involving a walk along a leafy suburban street, but the Hanger Lane to Park Royal OSI already exists and performs much the same function - albeit it is a far less pleasant OSI walking alongside the busy A40.

Lots of people enter London via Euston and the Lioness Line to South Hampstead would provide a useful short cut for anyone going north on the Metropolitan or Jubilee Lines. It would save them the walk from Euston to Euston Square, and remove the need for them to travel on the busy section between Euston Square and Baker Street. I thought the Overground was meant to encourage such journeys to take people out of the centre...

With respect to Ealing, I was more thinking of people trying to get to Heathrow. I accept that Rayners Lane to West Ealing is probably not that frequent, but what about Rayners Lane to Heathrow? I think some people may prefer to rake the Elizabeth Line from Ealing Broadway rather than change at Acton Town.

Anyway, this is all just wishful thinking anyway. I don't know what criteria Tfl actually use for OSIs, but it's always a bit surprising to me that Park Royal to Hanger Lane persists when more "sane" interchanges are overlooked.
