Yes that is more analogous to the MBTA which operates its subway and trolley lines and contracts with keolis to operate the commuter rail lines.
But I think that is the wrong level to contract out at or they should split up the contract at least. Contract out the maintenance perhaps, but not just with one provider. Big contracts are synonymous with big failures. Best to break up contracts to as many vendors as is practical if you go that route. At least 3 to keep it competitive.
No, it's not really analogous. Metra is in the uniquely weird position of having 6 of North America's 7 largest Class I freight railroads owning track in its district. They have the most entangled landlord situation of any passenger rail operator on the continent.
-- Metra Electric (all Metra-owned)
-- BNSF Line (BNSF-owned/operated)
-- UP North Line (Union Pacific-owned/operated)
-- UP Northwest Line (Union Pacific-owned/operated)
-- UP West Line (Union Pacific-owned/operated)
-- Milwaukee District North (some Metra-owned, some Canadian Pacific-owned, CP dispatched)
-- Milwaukee District South (some Metra-owned, some Canadian Pacific-owned)
-- Heritage Corridor (some Metra-owned, some Canadian National-owned)
-- North Central (some Metra-owned, some Canadian National-owned)
-- Rock Island District (some Metra-owned, some CSX-owned)
-- SouthWest (Norfolk Southern-owned)
Except for the 100% in-house Electric District their ownership is cobbled together out of basically the first 10 miles of track from the terminal on the lines they have some ownership stake in, and then the rest they are all tenants on. Some they paid to lease the dispatching control of, and others the freights do all the dispatching. And then Union Pacific (the #1 largest freight carrier on the continent) and BNSF (#2 largest) demand to operate any passenger trains in their ownership territories, preventing Metra from keeping a 100% in-house operation.
There isn't any comparison in the world for how complex Metra's track ownership situation is. The only 'foreign' territory the T ever had to operate in since the start of the modern public-owned commuter rail system in 1976 was:
-- Amtrak ownership, NEC @ RI border and points south + Amtrak NEC dispatching South Station and points south, 1976-present.
-- Conrail/CSX ownership, T-controlled dispatching on Franklin Line, Franklin Jct. to Forge Park, 1988-present.
-- Conrail/CSX ownership + dispatching on the outer Worcester Line, 1994-2012.
-- Conrail/CSX dispatching on the T-owned inner Worcester Line, 1976-2012.
-- Boston & Maine/Guilford Rail System ownership + dispatching on the Fitchburg-Gardner portion of the Fitchburg Line, 1980-88. Service cut back to Fitchburg after Guilford revoked dispatching access in retaliation for losing the 1987 operating contract renewal to Amtrak.
-- Boston & Maine, Lowell Line from Lowell-Concord, ownership from state line to Concord, dispatching from Lowell to Concord, 1980-81.
All of these have been taken care of. T owns and dispatches all the way to Worcester now. They have control of the little sliver of CSX ownership they run in to reach Forge Park, as well as a baked-in purchase option on that 1988 contract to buy the whole Milford Branch whenever they please. The NEC and South Station sharing agreement with Amtrak has been baked into place since '76, and has more protection against turf wars than what MARC, SEPTA, and NJT deal with on the NEC. They secured 'perpetual' passenger and dispatch rights from Lowell to Concord from Pan Am when they were trading land deeds at Northpoint, so Nashua and/or Concord service is already locked down under their complete ops control for when that happens. They have 'perpetual' passenger rights secured for Wachusett to avoid the ugliness with Gardner control the last time around, and may outright buy that 10 miles of track and associated dispatching before the new extension stop opens.
There's zero landlord conflicts muddying up the waters. Every commuter rail line is under internal lock-and-key. Every potential future commuter rail line, including the border-crosser to Nashua or Concord, is under internal lock-and-key. So they have no private entities they have to cooperate with if they pull ops in-house. Just the usual Amtrak/NEC agreements that have been unchanging for 39 years and 4 different operators.
