Unique features of the Bakerloo

Also there's a ground frame at East Putney, and Gunnersbury has already been mentioned.

In terms of official names then probably so, but don't forget the ''Goblin'' is now within TfL's purview.

Also, ''Chelney'' (if ever built) is about equally likely to be called that as ''Crossrail 2'', but this will be named for teh areas of London served, not stations.

Also I seem to remember one of the proposed names for what became the Victoria was the ''Viking Line'' (Victoria + Kings Cross)

I knew there was another one, but couldn't remember it. I do remember the same author saying the Victoria Line name was chosen not because it was particularly good but because nobody could think of anything better.

Slightly OT, but when I was born my family lived on London Road in High Wycombe. ;D

Only line to have a deep level terminus at one end, and an open air terminus at the other end.

Up until 1968, the only full length LU line (as opposed to a branch) with a deep level terminus

Westminster

There used to be an Enfield West

or Eastcote ;D

West Silvertown is now unique, previously there was Silvertown (and London City Airport)
South Kenton has only Kenton for company, similarly there is Aldgate East, Waterloo East, South Wimbledon, South Tottenham and Dagenham East ("Hale", "Heathway" and "Dock" are not cardinal points). Now South Kentish Town is no more Kentish Town West also fits the bill.

Arguably, West India Quay and East India are members of the set too.

If "Central" is taken as a cardinal point then Hendon Central, Heathrow Central, Hackney Central and Walthamstow Central all can be admitted tot he club. If "Central" isn't, then North Wembley will be eligible for membership.

Northwood, Northwood Hills, Westferry, Westbourne Park, Southfields and Southgate are all of the Westminster ilk.

Probably the most confusing pair of stations though, Bromley South and South Bromley (which co-existed with these names between 1899 and 1944)!

West Brompton is good...there was a Brompton Road...
I suppose it all depends on how you phrase the question,doesn't it?
By "Station" I really meant station of any operator,I think,but a passenger station.
Perhaps "Cardinal Points" is too limiting a phrase....perhaps I should have said "Geographical qualifier"?
With this in mind,why is it called Lambeth North?
I know it is in the North of Lambeth,but it is the only station with Lambeth in its name.
Let me reset the question....are there any stations with a geographical qualifier in their name whereby there never have been any other stations (of any operator) in the vicinity with either another geographical qualifier (or none at all) apart from Lambeth North.
By "Name" I mean,of course,to include subsidiary names,and to have been the official name carried by the station concerned.

Stations - North Weald ? South Weald never had a station.

Terminals under and overground. As well as the Bakerloo, the original Piccadilly Line, Hamsptead Line (although one branch was all underground), and the Central London line from the time of the extention to Wood Lane until the eastern extentions were opened after WW2.

I am enjoying this thread.

Wasn't it known as something else prior to Westminster Road Bridge before Lambeth North?

Yes, Kennington Road between opening on 10 March 1906 and 4 August 1906.
It was Westminster Bridge Road from 5 August 1906 until 14 April 1917. Since 15 April 1917 it's been Lambeth North.
