In [[London]]'s [[London Underground|deep-level tube network]], these usually occur in pairs for both directions of two lines. This allows for extremely quick and convenient interchange. The effect is that the two lines, despite having completely separate operation, can be treated by passengers as branches of a single network.

Examples include:
* Several slow and fast services have multiple cross-platform interchanges. [[Finchley Road tube station|Finchley Road]] offers cross platform transfers between the fast [[Metropolitan line]] and slow [[Jubilee line]] at surface level before diverging from [[Wembley Park tube station|Wembley Park]]. [[Acton Town tube station|Acton Town]], [[Barons Court tube station|Barons Court]], [[Turnham Green tube station|Turnham Green]] and [[Hammersmith tube station (Piccadilly and District lines)|Hammersmith]] all have cross platform transfers between the fast [[Piccadilly line]] and the slow [[District line]].
* [[Mile End tube station|Mile End]] has cross platform transfers between the [[District line|District]]/[[Hammersmith & City line|Hammersmith & City]] and [[Central line (London Underground)|Central]] lines at sub-surface level.
* [[Barking station|Barking]] has cross platform transfers between [[District line|District]]/[[Hammersmith & City line|Hammersmith & City]] lines and [[c2c]] services from platform 3, 4, 5 and 6.
* [[Stratford station|Stratford]] has cross platform between the [[Central line (London Underground)|Central line]] and [[Elizabeth line]] services.<ref name=stratford />
* For the deep-level interchanges the term "same level interchange" is sometimes preferred as there is invariably an intermediate circulating area between the platforms.  Convenient same level interchanges feature at various [[Victoria line]] stations, including [[Stockwell tube station|Stockwell]] with the [[Northern line]] and [[Euston tube station|Euston]] with the Bank branch of the [[Northern line]]; [[Oxford Circus tube station|Oxford Circus]] with the [[Bakerloo line]]; [[Finsbury Park station|Finsbury Park]] with the [[Piccadilly line]]; and [[Highbury and Islington]] with the [[Northern City Line]]. There is also a cross platform interchange at [[Baker Street tube station|Baker Street]] between the Bakerloo and Jubilee lines, and a cross platform interchange at [[Kennington tube station|Kennington]] between the Charing Cross and Bank branches of the Northern line, which during normal service times operates as two separate branches south of [[Camden Town tube station|Camden Town]].
