Surely the infrastructure network is a different concept to the train

The UK overland railway network is managed and owned by network rail.
How about this for a thought:
For the trains, a network might be linked to a brand; An operator may
have distinct branding for commuter services, intercity services and
freight operations giving three different "networks." All the services
within a network will be integrated in terms of scheduling and other
planning, whereas coordination with other networks is a whole different
can of worms. If there is just one big team doing the planning, then
it's one network. If the planning is done reasonably autonomously, then
they are different networks.
All investment in the overland rail structure is via Network Rail
Is "London Overground" a separate "network" to the Underground? Is the
DLR a separate network? Instinctively I would say yes to both of these,
from both a train service point of view and from an infrastructure point
of view. Pleased to hear arguments to the contrary though.
There are other networks such as the such as Midland Metro, Dockland
Light Railway and London Underground as well as other metro/tram
networks. These tend to be owned and run by local transport authorities.
Transport for West Midlands for Midlands Metro and TFL Transport for
London for DLR and London Underground. These manage both the rolling
stock and the tracks while Network Rail does not actually own any
rolling stock - as far as I am aware - except perhaps for maintenance
vehicles, although I would not be surprised if the maintenance companies
owned them!
So DLT has a network=Transport for London and an operator=Transport for
London ... in my book. The other metro lines are similarly owned and
operated.
