One of the reasons for the creation of so many branches was as a way of a third party company making money by building a "threat railroad" that either the B&M or B&L or Eastern would have to buy to avoid it falling into the hands of it's competitor.
Interesting lines that may fall into that category include the "New and Middle Route" that ran from Newburyport to Boston via Wakefield.
This broke the monopoly on passenger service from Newburyport that the Eastern RR enjoyed.
The Essex RR ran from N. Andover MA to Salem MA via N. Andover, Middleton, Danvers, Peabody.
The Essex when combined with trackage rights in Lawrence and the Manchester and Lawrence provided a way of getting coal from Salem MA up to Manchester and beyond.
Another interesting line was the Lowell and Lawrence. It ran from just over the river in N. Lawrence to Lowell via Andover and Tewksbury. When combined with the Salem and Lowell and the Boston and Lowell it provided a way to get from Lawrence to Boston via Andover, Tewksbury, Wilmington Jct, then the B&L line to Boston.
The Salem and Lowell is interesting in that it never made it to Salem or Lowell. It ran from Tewksbury Jct in Tewksbury to a junction with the Essex RR in Peabody. It depended on trackage rights to get into Salem and to get into Lowell. It used the Lowell and Lawrence to get into Lowell.
That gave the Boston and Lowell access to Salem. At the time the Boston and Maine had built it's own line to Boston and no longer used the present Wildcat to get to Wilmington to continue to Boston over the B&L.
The B&L offered service from Lowell to Boston by running from Lawrence, Andover, Tewksbury, then instead of crossing over the B&M on the Salem and Lowell, it ran down the present Wildcat to Wilmington and onto B&L to Boston.
Don't forget about the former S. Reading Branch. It ran from S. Reading to S. Danvers. S. Danvers is now Peabody and S. Reading is Wakefield. It was a way for going from Salem MA to Boston via the B&M instead of the Eastern.
The Saugus Branch was a threat railroad that provided a way for people in Saugus to get to Boston via the B&M instead of the Eastern. The Eastern ended up buy it or getting control and rerouted the line back to the Eastern Route and eliminated the connection with the B&M.
The Georgetown Branch allowed for an easy route from Haverhill to Newburyport via the line from Wakefield to Newburyport. the Georgtown branch connected with the Wakefield to Newburyport line in Georgetown. It provided an alternate route to Boston but I suspect that wasn't of much value.
The West Amesbury and Amesbury branches simply ran out of customers and were abandoned. West Amesbury was the former name of Merrimac MA. There was talk to the two lines being connected but that never happened.
There are more but that's enough for now.
