Light Rail - The Facts;
Critics refute Federal Reserve arguments
Evaluating
Public Transit Benefits in St. Louis
Critique of "Light Rail Boon or Boondoggle" By Todd Litman
Victoria Transport Policy Institute
27 July 2004
Summary
There has been
considerable debate over the value of rail transit service. Critics
argue that it is economically inefficient and more costly than alternatives,
but their analysis often focuses on just one or two of the full
economic, social and environmental benefits provided by high quality
transit, and underestimates the full costs of accommodating additional
automobile traffic on the same corridors. Rail transit can improve
mobility for non-drivers, reduce automobile travel and associated
costs, and support more efficient land use patterns. As a result,
communities with major rail transit systems tend to have less per
capita traffic congestion, lower per capita traffic fatalities,
lower road and parking facility costs, and consumer cost savings.
On congested urban corridors, automobile costs (road and parking
facility capacity, congestion impacts, accident impacts and pollution
emission damages) are higher than average, resulting in greater
than average savings from shifts to alternative modes. Although
it would not be cost effective to provide light rail transit service
everywhere, when all costs and benefits are considered, rail transit
is often the most cost effective way to improve transportation on
major urban travel corridors. A recent paper by Molly D. Castelazo
and Thomas A. Garrett ("Light Rail: Boon or Boondoggle" 2004) exhibits
typical errors by rail critics. It ignores many benefits of rail
transit and understates the costs of automobile travel on the same
corridors. Their study fails to reflect current best practices for
comparing highway and transit investment cost effectiveness.

Introduction
The recent
paper authored by Mr. Garrett and Ms Castelazo, St. Louis Fed economists,
presented in the July issue of the Regional Economist titled "Light
Rail Boon or Boondoggle?" is based upon a series of premises that
neither reflect the real world nor lead to productive analysis of
public investments. A later more extensive version has been posted
that represents an extension of the comments in the article published
in the Regional Economist. This paper represents comment on the
expanded version The paper is incomplete in analysis and amounts
to a tendentious recitation of standard Libertarian rhetoric.
Perhaps the
most complete recent work on valuing public transit improvements
was published July 23, 2004 by the Victoria Transport Policy Institute
and is authored by Todd Litman. The authors of the instant study
would do well to consult this material in order that they might
at least start with a complete list of the potential beneficial
effects of public transportation improvements as well as a more
complete formulation of the externalities of an automobile based
transportation system and its expansion.
Litman lists
some five major categories of benefits: Mobility, Efficiency, Travel
Time Savings, Land Use and Economic Development. He breaks these
down into some twenty-two sub-categories and posits a series of
mechanisms for their evaluation. The current paper treats but one
of the four subcategories under Mobility, but two of seven under
Efficiency, includes no discussion of Travel Time Impacts, a woefully
inadequate discussion of Land Use Impacts and under Economic Development
Impacts discusses few considerations beyond the possible impact
on nearly residential values that it finds generally positive. It
largely ignores all six of the sub-categories.
Assumption:
value is solely determined by profit potential
However, the
over-arching problem is the assumption that value in public investment
is to be measured by the potential of the investment to produce
a profit. This approach ignores the value of public goods and would
support the proposition that almost every public investment is of
questionable value. The fact is that public investment occurs when
private persons, motivated by the profit motive, abjure from investments
in the same or similar improvements. The decision-making with respect
to public investments is inspired by a variety of motivations. They
include all of Litman's five categories and twenty-two subcategories.
They include mobility, education, reduction of health risk, economic
development, cultural and recreational enhancement. To the degree
that the value of these motivations is denigrated in favor of profit
potential, public goods such as public transportation improvements
(including construction of city streets and interstate highways),
museums, zoos, public schools, public universities, subvention in
the form of scholarships, public recreational facilities, public
art, public communication, symphonies, opera companies and public
health facilities would be absent from our society. The only substitute
for such investment would be charitable giving.
Indeed, we
would return to a feudal era in which the Lord of the Manor (the
historical equivalent of the super rich of today) would be the sole
arbiter of societal investment, a result that has no measurable
public acceptance.
Assumption:
taxes are bad when they confer a service on a group more narrow
than the general population
The contention
throughout the paper is that public transit and particularly rail
transit confers benefit only on the daily commuter and is primarily
to be justified by aid to the poor. Almost all public services save
defense law enforcement and fire protection may be subject to same
observation. From public education to art museums, parks to public
playgrounds, public education to swimming pools the beneficiaries
are few compared to the number of taxpayers. The societal conscensus
has been, however, that the provision of public amenity is a worthy
end. In summary, with taxes I buy civilization.
Assumption:
sole value of public transit is access for the poor to employment
Just as public
streets and highways are constructed to afford mobility to the larger
society, public transit enjoys a constituency larger than those
who are forced by economic necessity to patronize the service. If
indeed other examples of public investment were measured solely
on their value to the poor, none of these investments would measure
well. There is a panoply of examples of public transportation investments
oriented toward the larger purpose of affording mobility, light
rail among them. They have included public subsidies for the development
of air travel and space travel; for the construction of roads, railways
and canals; land grants to afford access to developing areas and
investment in regulatory authority to protect public safety in the
use of such improvements.
The paper fails
to value the benefit to the general public of the MetroLink in improvements
in roadways foregone, air pollution not created to say nothing of
fostering a more efficient land use that can be provided utility
and general services at a lower cost. There is no value placed on
the reduction of sprawl that otherwise promotes the costly relocation
of public institutions and cultural infrastructure. No value is
assigned to the enhanced availability of mobility to the elderly,
the young and the physically handicapped nor to the speed and avoidance
of congestion that light rail affords to its patrons. In short,
the assumption that the value of the improvement is determined solely
by its utility to the poor represents an incomplete and faulty analysis.
It is also
worth noting as a parenthetical matter that services that are provided
solely to the poor in American society are almost uniformly poorly
run and inadequate. We need only recall the failures of public housing,
public hospitals and services directed to poor neighborhoods. Services
provided to a broader slice of the society reflect the expectations
and demands of that portion of the constituency that expects and
can demand quality.
Given the
assumptions, the numbers are wrong
The numbers
for the operating subsidy and cost of capital are just plain wrong.
The most significant error appears to be that the capital cost figure
for 2001 includes payment of construction cost taking place in that
year as an element of the St. Clair County construction.
In 2001 the
operating subsidy (Operating Expense less Operating Revenue) was
$14,096, 428. The actual capital Amortization was $1,176,883 and
the Opportunity Cost for $348,000,000 at 8% would be $27,840,367.
Note that assigning opportunity for these investments at 8% seems
grossly excessive, given the fact that local borrowing is tax exempt
and the relatively low historical federal governmental borrowing
rate. A 1998 financing for the St. Clair Extension was concluded
at approximately 5.2%, a partial refinancing was concluded in the
3.5% range and the current federal government 30 year real cost
of government borrowing according to OMB Circular C is 3.5% and
in 2002 (an appropriate year for prediction based upon 2001 results)
was 3.9$. A blended opportunity cost pegged at 4.2% would be $14,616,000.
Thus depending upon the opportunity cost the annual subsidy based
upon FY 2001 would range from would range from $43,113,311 to $29,889,311
or a subsidy of $2.43/trip to $2.09/trip (based upon 14,288,976
trips).
The tyranny
of false choices
Perhaps the
most glaring of the false premises that the paper indulges leads
to its comparison of false choices. Any person who is familiar with
the politics and public policies that animate American society knows
that tolling all auto facilities or raising the gasoline tax to
a level that would satisfy even the direct costs of the auto oriented
society is a neither a probability nor a possibility. Perhaps the
most dearly held value among Americans is the opportunity of personal
mobility. What public transit and light rail represents is an attempt
to leaven the effects of this over-riding motivation with a means
of exercising some moderation in its pursuit as well as lend some
modicom of choices to the larger society.
Assumption:
subsidy for development or transit is a bad thing
First, much
as the authors might wish, almost all development is the beneficiary
of subsidy in one form or another. From FHA insured mortgages that
built the suburbs after the Second World War to the TIF program
responsible for the suburban commercial explosion to the fact that
utility extensions are largely subsidized by existing rate payers
there is obvious and not so obvious tinkering with the so-called
free market. Who is to say that cities and inner suburbs out not
receive some payback for the contribution they have made to sprawl
development.
Value is
a product of an investments contribution to larger purposes
If the numbers
were correct (see above) perhaps the most trenchant criticism of
the paper is that it is an example of analysis that it is aware
of the cost of everything but the value of nothing. Rail transit
is a concomitant to the success of every great city both in this
country and elsewhere in the world. In this country New York, Boston,
Washington D.C., Atlanta, San Francisco, Portland and San Diego
come to mind. Cities that are only now developing rail have suffered
from sprawl and are now attempting to redress the balance. Los Angeles,
Salt Lake City and Denver are examples. Sole reliance on the auto
is a hallmark of municipal failure. Detroit is perhaps the most
notable example. Further, cities themselves are the repositories
of the commerce, culture and learning of the society, their preservation
and enhancement is a public value of the highest order.
A not inconsiderable
benefit of MetroLink has been the economic development that it has
already accompanied its development and is planned for the future.
The new Cardinal Stadium was placed at its new Downtown site partially
because of its MetroLink access, Webster University's enlarged Downtown
presence has been stimulated in part by the expansion of MetroLink
to serve a station near the main campus in Webster Groves. Downtown
has seen a major residential revival, the area near the BJC complex
is alive with new development both by the Medical Center and by
independent development interests, The Delmar Loop Extension to
the Delmar MetroLink Station was inspired by MetroLink, Emerson
Park represents the first mixed income development in East St. Louis
within the memory of man and a second phase is now under construction,
there are several additional Transit Oriented Developments about
ready to move forward at other St. Clair County Stations.
It is indeed
impossible to engage in single factor analysis with respect to the
motivating factor for these and other developments as well as the
remarkable run-up in residential values along the alignment, particularly
in St. Louis' Central West End and Skinker-DeBaliviere neighborhoods.
It is also impossible to fully isolate the impact ofr transit improvements
on residential values such as the instant study attempted.
What this City
needs and is beginning to develop is a sustainable urban fabric.
The City and the inner suburbs are beginning to prosper and the
enhancement of our rail infrastructure is a key part of future success.
All would be better off if the St. Louis Fed, long regarded as a
distinguished example of economic scholarship, would avoid parroting
the nostrums of a Libertarian fantasy world.
Light Rail
Transit: A Bargain Compared to Toll Roads
By E. L.
Tennyson, P.E. with editing and comments by Dave Dobbs, Texas Association
for Public Transportation, publisher http://www.lightrailnow.org,
and Lyndon Henry
Light Rail
Transit (LRT) is far less costly than toll roads if they are both
built on the same or similar right-of-way. Light Rail in a subway
will be more expensive than a toll highway on terra firma, but LRT
will have far more capacity.
Basically,
Light Rail on a right-of-way (ROW) that has no buildings on it averages
about $20 million per double-track mile excluding rolling stock
and shops. It will typically carry 1,500 to 3,500 people in the
peak hour one-way but could carry 14,000 people per hour if, as
in Boston, there is a need to do so.
Where it is
necessary to rebuild the streets, LRT costs jump to $30 million
a mile and if it is elevated on structure, $60 million a mile is
typical. LRT elevated on structures over streets may run $80 million
a mile or more. In other words, project costs, highways or transit,
vary with the amount of concrete, excavation, utility relocation,
right-of-way acquisition, etc., required. To keep this simple, let
us consider only ground-level LRT and freeways on undeveloped land.
Assuming 4.5
million passengers annually or about 1500 one-way peak-hour trips
on a $20-million-per-mile Light Rail line, the annualized capital
cost per passenger is approximately 11 cents. If, as is true for
several U.S. LRT systems today, the one-way peak-hour travel exceeds
3000 riders, that cost drops to 5 cents per passenger or less (10
million riders annually or more). Operating costs will add 30 to
50 cents to that depending upon the skill of the management and
the wage scales.
With a roadway,
1500 passenger trips per hour in one direction requires a four-lane
freeway with interchanges* at $17 million a lane mile or $68 million
per mile total compared with $20 million per mile for double-tracked
LRT. The seemingly high cost of Light Rail Vehicles (LRVs) is often
a target of criticism. However, with a 30-year economic life and
high passenger capacity, LRVs compare very favorably to the cost
of automobiles per passenger-mile carried. For example, an LRV will
typically average about 1,000 weekday passengers and 290,000 per
year, for a typical average passenger trip length of about 5 miles.
At $ 100,000 per year to buy the LRV, this comes to 7 cents per
passenger-mile.
Automobiles
cost $20,000 to buy (some more, some less), and will cover approximately
10,000 miles a year in predominantly commuter service. If we assume
a 10-year economic life, the automobile will cost about $2,000 per
year, or about $0.20/mile for 10,000 miles/year. With an average
occupancy of 1.2 persons, that becomes 17 cents per passenger-mile
(p-m), which is more than twice the cost of the LRV at 7 cents per
p-m.
In terms of
total capital and operating costs, LRT - particularly surface LRT
- is also significantly more economical. For example, San Diego's
extremely cost-effective LRT has a total cost of about $0.52/p-m.
Other surface-routed LRT systems have a total cost more in the neighborhood
of $0.80/p-m. In contrast, the automobile has a total cost of about
$0.53/p-m (APTA), to which must be added about $0.60 per p-m for
commuter parking - for a total cost of about $1.10-1.15 per p-m.
All in all, LRT by these measures is by far a more cost-effective
mobility investment.
Now, if one
compares freeway costs to LRT costs at higher passenger volumes
(3500 people/hour), roadway capital costs go up 50% to $102 million
for the six lanes required to move those same 3500 people per hour
one-way in both AM and PM peak hours. Excluding the cost of the
extra rail cars that may be required to handle higher volumes, LRT
capital costs will either remain the same or rise only slightly
if the transit agency has to purchase more cars and/or improve signaling.
(See freeway capacity assumptions in Note 3.)
In terms of
a "ballpark" estimate, this means that freeways capable of handling
typical urban hourly peak passenger loads are five times as expensive
per mile to build as equivalent LRT, systems while the costs per
passenger mile are not that different. Since toll roads are usually
built with borrowed money, a six-lane grade separated facility like
the one discussed here could easily exceed $200 million per mile
over the thirty-year life of the bonds due to interest costs, much
more than an equivalent LRT line similarly built with debt (e.g.,
$20 million per mile plus $20 million debt service over 30 years).
While it can
be argued that over a 24-hour day most six-lane urban freeways handle
several times the total number of passengers annually than most
LRT lines do, this does not address the peak-hour mobility capacity
problem where rail delivers passengers on time for far less cost
as traffic volumes increase. Additionally this discussion does not
address the cost of parking, lost tax base, or pollution where the
auto-roadway system has far higher negative externalities relative
to LRT.
* NOTE: Without
interchanges half the roadway's capacity is lost, as traffic signals
at intersections will be required. Interchanges characteristically
consume half a square mile or more and freeways typically need 300
to 500 feet of right of way. This represents an enormous loss of
very valuable tax base, which is not included here. Although light
rail can operate in very narrow rights of way (as little as 34 feet),
most LRT ROWs are normally just 60 to 80 feet wide at most.
Sources: (1)
Actual LRT construction costs are based upon Denver SW, Portland
Airport, Sacramento east extension, Salt Lake City south (Sandy)
and St. Louis Metrolink extension to Scott AFB. (2) Commuter automobile
costs of 53 cents per passenger mile are based on AAA and Runzheimer
data, plus parking. Because of high costs at VTA (Santa Clara),
SEPTA, Pittsburgh, and Buffalo (the last three systems have subways,
escalators, elevators, drains, pumps, lighting, etc., operating
all day), the FTA national average for LRT is 52 cents per passenger
mile, but most light rail systems carry passengers for 30 to 50
cents per mile. (3) Highway costs are based on the proposed InterCounty
Connector in the outer Maryland suburbs. (4) AASHTO Highway Traffic
Manual assumes 2,200 vehicles per lane per hour but illegal tailgating
or perfect operation is implied in that number. At Level of Service
"F", the normal state of urban freeways at peak periods, congestion
drops capacity to 1,350 vehicles per hour or 1,500 people at 1.15
passengers per peak vehicle. With families traveling, vehicle loading
is higher on Sundays. Even using the highest number (2,200) does
not change the determination in this discussion enough to matter.

Critique
by Lyndon Henry
An article
and report produced by personnel of the Federal Reserve Bank of
St. Louis in the summer of 2004 vigorously attacking mass transit
and light rail systems have far more of the character of political
tracts than well-reasoned, fact-based analysis conducive to sound
public policy decisionmaking. Identifying and understanding these
fallacies and serious methodological weaknesses is critical to furthering
sound transportation decisionmaking in US cities such as St. Louis.
