Last week, New Jersey governor Chris Christie made headlines (in a small segment of the population at least) by poo-pooing entreaties to extend the Camden-Trenton River Line to the Statehouse, telling riders to “Use Uber” instead. Now, the River Line is seemingly mediocre transit; despite forming a strategic link between two depressed cities, and connecting to strong transit options on both ends, its farebox recovery is atrocious (although it has shown some returns for the region).
That being said, it’s clear that the River Line’s Trenton terminus is in a less-than-ideal location. Although it connects well with SEPTA, NJT, and Amtrak trains, I think it’s fair to assume that most River Line riders are local, rather than making connections to destinations along the Northeast Corridor. And to reach many of the government jobs in downtown Trenton, those riders will have to walk a decent distance or transfer to a collection of buses branded as “Capital Connection.”
The Trenton Transit Center is on the far eastern end of the heaviest job concentration in Trenton.
So: even if the River Line is mediocre transit, extending it a few more blocks into downtown Trenton isn’t a waste–it’s a key network connection that holds potential to be highly useful to lots of riders. And that’s where my take on the potential extension differs from Gov. Christie’s. Where the governor sees a question of expanding an underperforming transit system–that is, in a sense, rewarding underperformance–I see an attempt to redeem that same system with a relatively minor expenditure based on the principle of network connections. Indeed, is it possible that the statehouse connection could be the key to unlocking the River Line’s overall potential?
Much the same logic has been at work in Massachusetts, where Governor Charlie Baker has posed a dichotomy between “core operation” and “expansion,” as told to Politico:
“It just so happens our capital investment is in its core operation and not in expansion. But we see what happens when you spend all your money on the shiny new thing and forget about the fact that you have a core system that you need to invest in, to maintain, to enhance, and to modernize”
Baker’s commitment to this dichotomy has played out mostly in his administration’s skepticism toward the Green Line Extension into Somerville and Medford, and to a lesser extent on the North-South Rail Link. Baker has a point, of course, that MBTA and the state of Massachusetts have shown little capacity for effective project management, and there is a crying need to fix the maintenance and State of Good Repair backlogs facing the existing system.
But, like Christie, Baker fails to understand that the Green Line Extension and NSRL represent not “expansion” for its own sake but targeted infrastructural investments on the principle of building a transit network. Indeed, NSRL would enable the transformation of the MBTA commuter rail system from a collection of disconnected dead-end lines into a real network. In the dichotomous lingo that has taken effect in Boston, NSRL represents neither reform nor revenue, but reform through revenue (or really, investment), which, when needed, is the core logic of network-based thinking. It would take the system from this:
To illuminate the conceptual challenge in convincing politicians to think in terms of networks, let’s turn to Jarrett Walker’s well-timed (for my purposes!) post from yesterday on core vs. edge debates. Of course, core/periphery fights are not precisely the same issue as opposing “expansion” that actually represents a key network link–but both represent a failure to think in terms of networks. In Jarrett’s words:
Once more with feeling: Transit is a network, which means that its parts are interdependent. You cannot think about it the way you think about libraries or fire stations, where putting one in a certain place clearly benefits the people there, because the whole network affects everyone’s ability to get everywhere.
This is the key concept that, it seems, Christie and Baker have failed to grasp. Certainly, there are transit expansions that benefit only a discrete set of people within a region; many (politically popular) commuter rail and light rail extensions into low-density areas fall into this category. But many “expansions” have utility well beyond their own immediate area. The key is for decision makers to be able to differentiate between different kinds of “expansion”–and, in fairness to Christie and Baker, the political incentives are largely set up to make this differentiation hard.
Politicians face pressure to “give” everyone (that is, all geographic areas) benefits from government spending, which–and this is where we return to the parallels with the core/periphery problem–incentivizes spreading money around inefficiently rather than investing in geographically central yet regionally (networkily?) beneficial links. Would Christie or, especially, Baker, be more willing to risk some political capital on an “expansion” if it were seen as a key network link rather than a luxury whose benefits accrue to one particular area? Maybe, maybe not. But those of us with a stronger grasp of the concepts behind the transit can work on educating, those nonspecialists whose first instinct is to respond to the loudest voices.
