Plymouth & Brockton Street Railway Company
Plymouth & Brockton Street Railway Company carried 432,964 boardings in FY2016 at $16.50 per ride and $-0.08 in subsidy per ride. Ten years of NTD data, by mode.
What those two numbers mean
Passengers aboard is passenger miles divided by vehicle miles: how many people are on board on average, at any moment. It is the missing term in cost per ride. A service carrying twenty people per vehicle mile and one carrying half a person can spend the same on fuel and wages and arrive at wildly different costs per passenger.
Average speed is vehicle miles divided by vehicle hours, including every stop and every red light. It is the hidden term in cost per mile, because cost per mile is cost per hour divided by speed. A bus network slowing from 13 mph to 11 becomes a fifth more expensive per mile with no change in wages and no change in service.
By the numbers
By the numbers
FY2016 unless noted. Each figure is computed from what the agency filed with NTD, and set against something to read it by.
Fares were 50% of all the money that paid for operations. That is lower than the 100% fare recovery on this page, because these funding figures also cover depreciation and pension costs that operating cost leaves out.
- Fares 50%
- Other directly generated 50%
Revenue hours bought from a private operator or another agency rather than run in-house. Nationally, much of this is paratransit.
U.S. transit: 25% of service hours
A journey with a transfer counts as two rides, because NTD counts each boarding.
The year's boardings divided by 365. Weekdays run higher, weekends lower.

Why cost per ride moved
Indexed to FY2015 = 100, in constant dollars
Cost per ride is the cost of an hour of service divided by the riders carried in that hour. It can only rise for two reasons: service got dearer to produce, or fewer people rode it.
Where the money goes
Operating cost by function
Who pays for it
Federal, state and local funding, 2008 to 2016
Operating and capital money together, in the dollars of each year. Fares are not in this file — FTA took them out of the funding series in 2022 — so "directly generated" here means advertising, concessions, park and ride and taxes the agency levies itself. The farebox is charted above.
Capital
Capital spending
What was spent on building, rebuilding and replacing, shown beside the cost of running the service rather than folded into it.
FTA publishes the capital files from 2022 onward, and this agency does not appear in them.

Against the U.S. rate for the same mix of service
The dashed line is not the national average. It is what the national rate would be for this agency's own service: each mode it runs, charged at that mode's U.S. rate for the year, in proportion to its miles. Rates differ tenfold between modes, so a railway read against a national figure made mostly of buses and vans would look dangerous for running rail.
Miles rather than boardings, because this series covers 2020, when service kept running and riders did not come. And sitting above the line is as likely to mean careful reporting as dangerous operation.
The longer record, 2008 to 2015
FTA's threshold-adjusted time series, which reaches back further than the incident file and is built to be compared across years
NTD's reporting threshold changed in 2010, 2015 and 2023. FTA publishes this series adjusted for those changes so the years can be read against each other; the unadjusted counts jump by a third in 2015 on the rule change alone.

How old the vehicles are, how many people run them, and how far they get between breakdowns.
How the fleet has aged, 2011 to 2016
Average vehicle age, weighted across every mode the agency runs
A rising line is not automatically bad and a falling one is not automatically good: a fleet gets younger the year an agency takes delivery, and older every year it does not. What the shape shows is whether replacement is steady or comes in bursts. The table below says how many vehicles are actually past the life FTA expects of them.
