Hi.
Don't you mix up network and owner corporation for New Jersey light rail system? As I can find in the Internet, the network is called Hudson-Bergen Light Rail (HBLR) and the owner is called "NJ Transit". Aren't they?Best regards,

Are they truly part of a different network? NJ Transit owns them, NJ Transit operates them, NJ Transit sets fares and sells tickets, and NJ Transit is what's painted on the vehicles. In my opinion, that justifies changing their network tags to match NJ Transit's bus and rail services.
Though I could see the case for either way. What advantage do you see in keeping their network tags as "HBLR" etc.?

The main advantage of putting network name to "network" tag and operator name to "operator" tag is to reflect the true state of things.
I think the three networks: Newark Light Rail, Hudson-Bergen Light Rail and Philadelphia River LINE - should be considered as separate networks because they are separated in space, NJ Transit separates them on its website, in particular provides distinct detailed map for each of them. But now the networks have lost their names in OSM and became indistinguishable, while "network" and "operator" tags duplicate each other.
BTW, though vehicle painting should not be a strong argument, I've easily found vehicle pictures with on-the-side "Newark Light Rail" and "Hudson-Bergen Light Rail" labels.

Should the Atlantic City Line be its own network, separate from the rest of the NJ Transit rail lines? Should the 'A' and 'B' divisions of the NYC Subway be separated into networks?
The issue you're having seems like it could be solved with a spatial query. If you're looking for only the HBLR, why not search for NJ Transit light rail in a bounding box? Or search for the route relations that make up the HBLR?
I think we're talking past each other here. I can see the case for keeping them distinct, and though I may disagree, I'm not gonna be mad if you change them back. I just don't see what the consequences are of this change.

I could meet my needs with a spacial query, fortunately these networks are not overlapping, what might not be the case. I still see a serious disadvantage of your approach: data coarsening/merging may be simply done at any time, while it's hard or impossible to restore details out of coarsened/averaged data. As I could find, Newark Light Rail or HBLR are real, distinguishable and identifiable network-like features which users may want to query OSM by name, without dealing with accurate geometry, outer sources or (God forbid!) hardcoding OSM ids.
Thank you for your patience and time.
