Frequency Works, Again

Last month I posted a quick note on the importance of frequency in transit, spurred by some research I’d done for my ongoing research project. Here’s another one, this time courtesy of the Philadelphia suburban rail system (today’s SEPTA Regional Rail). From this 1958 article in The Nation:

A similar experiment, is now being attempted on commuter lines serving Philadelphia–so far with a similar result. Philadelphia appropriated $160,000 on the promise of the Pennsylvania and the Reading to step up commuter and off-hour service to the northern residential suburbs. The Philadelphia, city fathers explained that they did not regard the $160,000 as an actual subsidy, but merely as an underwriting of increased operational costs, to see if improved rail service would take some of the clutter of cars off city highways. If this could be done, the pressure for ever larger highways, ever more bridges and tunnels, ever increasing parking facilities would be eased, and a subsidy to the railroads, even from the taxpayers’ standpoint, would justify itself.

The New York Herald Tribune reported last month on the Philadelphia experiment at the end of the first month of a six-month test period. The Pennsylvania had increased the number of trains on its Chestnut Hill run by 33 per cent to thirty-six daily; service was stepped up to every fifteen minutes in rush hours, every half-hour in off-hours. The Reading boosted the number of its trains from thirty-three to thirty six daily, Saturday service on both lines was almost doubled, and cheaper fares were tied in with bus-line  transfers. The result: In the fourth week of operation, the Pennsylvania carried 4,133 more passengers than it had in the test week of October 6, before the plan went into effect, a gain of 14.8 per cent; and the Reading picked up 2,422 passengers in the same week, an improvement of 7.6 per cent over its test week in May. For the entire four weeks, the Pennsylvania gained 11,128 additional riders; the Reading 7,099. The effect on city traffic already was observable; 600 fewer automobiles a day were coming into the city from the suburbs.

Philadelphia hopefully assessed the advantages of the plan this way: cheaper fares mean a saving, for the individual commuter, of 90 cents a day over automobile operation (including parking fees, insurance and fuel costs), or a total of $100 in the six months of the test period. This saving to the individual driver is projected into a much greater saving to the city. It means, Philadelphia estimates, that about $81 million annually can be saved on the cost of maintaining existing roads and providing police protection. And this is apart from the merry-go-round cost of building ever more and wider highways.

This was a truly different world for transit. SEPTA wouldn’t be formed until 1963, and it wouldn’t take over any responsibility for the commuter lines until 1966, or direct operation of them until 1983. And yet, the truth that frequency translates to ridership is apparent in this report. Indeed, the actions taken on the Pennsylvania’s Chestnut Hill West Line (the two Chestnut Hill lines run very close and parallel to each other, entirely within the boundaries of the city of Philadelphia), mirror closely the idealized set of recommendations that Jarrett Walker or any frequency-minded planner would make: clockface schedules, decent off-hours service, reduced fares, and schedule and fare coordination with buses.  There are, quite frankly, any number of transit agencies that can’t get their act together to make these things work in 2014. Perhaps we don’t give the people running our public transit systems during their decline phase in the 1950s enough credit?

Note: The numbers reported work out to a daily 1958 ridership of a little under 4,000 on Chestnut Hill West and about 4,400 on Chestnut Hill East before the experiment. Today, both lines carry about 5,500 riders daily, despite service that maxes out at half-hourly at peak and hourly off.
