A step heavier. For the London example, think more like the Overground, the Purple Train or Thameslink. Or the many railways radiating out.
For other examples, think systems like the LIRR in NYC, the RER in Paris or the S-bahn in most major German cities. (though the Berlin one functions more as a metro that’s just legally a train)
Re: legally a train
Metros and anything lighter are governed by different laws than trains. So German U-bahn is legally a tram, governed by the BOStrab, while S-bahn is legally a train, governed by the EBO
