PATH does, but I don't need to go there. London and Paris certainly do. Where do you think the term "RER" came from? I've linked the Crossrail and Thamslink info many times here, as well as Tramtrain, Karlsruhe model, etc, etc.NYC DOES NOT run commuter trains on the same tracks as it does it's subways
For London alone:
http://citytransport.info/Shared.htmTrack Sharing
- Hammersmith (Met) - Near Aldgate [Circle Line / Hammersmith & City Line].
- Just east of Baker Street - Near Aldgate [[Hammersmith & City / Metropolitan Line]
- Just east of Baker Street - Aldgate [[Circle Line / Metropolitan Line]
- Southern side Circle Line [Circle Line / District Line (main section)].
- Western side Circle Line [Circle Line / District Line (Edgware Road - Wimbledon service)].
- ‡Harrow-On-The-Hill - Moor Park - Amersham [Chiltern Railways / Metropolitan Line].
- *(Barons Court) - Acton Town - Ealing Common [District Line / Piccadilly Line].
- Rayners Lane - Uxbridge [Metropolitan Line / Piccadilly Line].
- Queens Park - Harrow & Wealdstone [Bakerloo Line / Euston-Watford London Overground].
- §Aldgate East - Barking [District Line / Hammersmith & City Line].
- Richmond - Gunnersbury [District Line / North London Line London Overground].
In London's case, where the Underground uses a unique four rail system (supply and drain are two separate rails) there's even a long established (almost a century ago) compromise to run the trains along with the mainline 'third rail electrics' (mostly ex Southern Region south of the Thames) to ensure compatibility electrically as well, as of course, the standard gauge tracks and platform height and distance from the rails to render them standard for use for both systems.

The older Metropolitan line train A Stock bound for Amersham
The lines are electrified with a four-rail DC system: a conductor rail between the rails is energised at −210 V and a rail outside the running rails at +420 V, giving a potential difference of 630 V. On the sections of line shared with main line trains, such as the District line from East Putney to Wimbledon and Gunnersbury to Richmond, and the Bakerloo line north of Queen's Park, the centre rail is bonded to the running rails, as the electrical return from National Rail trains is via the wheels.[8] This was first used in the early 20th century, the isolated traction current return allowing a train's position to be detected using DC track circuits, and reduced any earth leakage currents that could affect service pipes and telephone cables.[9]

"Newfangled"? My God...how stuck in the past is Toronto?
