(And I'm pretty sure that Marylebone NR and Baker Street LU are tied
together as being a valid OOSI, and I think this is also the case with
regards to Fenchurch Street NR and Tower Hill LU - though annoyingly
Paddington NR and Lancaster Gate LU is not an OOSI.)

Both true. As is Euston Square and Euston but not ES and Warren Street.
I've just been through to LU customer services and got one of the more
helpful members of their staff. They will try to assemble a list of
those interchanges. If they do, I will forward here.

They've just followed up to ask me to couch my request for information
as a Freedom of Information Act request. Heigh Ho!

They answered me, yesterday. Unfortunately, I can't copy the data un the
answer as they put the following in the reply: "Brief extracts of the
material may be reproduced under the fair dealing provisions of the
Copyright, Designs and Patents Act 1998". I think they mistakenly refer
to the 1988 Act, but know nothing and may be wrong.

However I can give a flavour.

The following interests me:
London Fenchurch Street Aldgate 30
London Fenchurch Street Bank 30
London Fenchurch Street Monument 30
London Fenchurch Street Tower Gateway 30
London Fenchurch Street Tower Hill 30

The example above illustrates that 30 minutes is the most common budget.
A curious exception is White City Wood Lane where 20 is allowed.

Tower Hill is obvious; I had found Aldgate, experimentally.
I am surprised Bank is allowed. Journey Planner shows a 13 minute walk.

Bank to Monument is not shown; I queried that - given maintenance.
I am inclined to think there ought to be a super interchange covering
Bank, Cannon Street, Mansion House, Monument, Moorgate and probably one
or two more while escalators are out for maintenance.

Times for interchange are not always symmetrical. e.g.
40 is allowed from Aldgate to London Fenchurch Street.

I have also questioned 30 Canary Wharf Heron Quays 10.

The information was supplied as 90 rows in an Excel file where each row
describes a one way interchange. I will probably recast that as 45 rows,
each describing a two way interchange.

They don't publicise or guarantee the data will remain true.

In my FOI question, I asked for a list of out of station pay as you go
interchanges and how long was budgeted for them. I got no answer to my
question on the criteria for such interchanges but am satisfied that I
now know how to make good use of out of station interchanges.
