Island Heavy Rail Calamity: San Juan Repeats in Honolulu

Island Heavy Rail Calamity: San Juan Repeats in Honolulu

by Panos Prevedouros PhD, Fix Oahu!

Tren Urbano (or City Train) in San Juan, Puerto Rico is a perfect comparison with Honolulu's heavy rail:

  1. Both are heavy rail systems with a very high cost per mile of rail line.
  2. Both are systems on similar tourist/agriculture/military island communities.
  3. Both are under Federal Transit Administration oversight.
  4. Both received US federal funds.
  5. Both have the same lead planner, Parsons Brinkerhoff.

I have written in the past about Tren Urbano:

Recently, Cliff Slater of has developed a documented 2-page summary of the consequences of Tren Urbano such as:

  • Huge escalation of construction costs (+74%).
  • Huge escalation of combined bus and rail operation and maintenance cost after the line was opened (+250%).
  • Downgrade of Puerto Rico’s bond ratings.
  • Dramatic decline of total transit ridership (bus and rail) because the Tren cannibalized their bus. This is happening to TheBus now.
  • It is now more than five years since its opening and Tren has not reached 50% of its opening year forecast ridership! (See link above where I provide comparisons that show HART ridership estimates are 2 to 4 times too high.)

Now all these terrible transit and financial outcomes occurred in San Juan where population is much higher, and average income and car ownership is much lower than Honolulu's (see 2000 data below). The Tren (like history) is repeating itself in Honolulu. The irresponsibility of current elected officials and certain candidates is truly bewildering.

Honolulu Rail Forecast 2 to 4 Times Higher than Actual Systems

FixOahu, September 4

The City estimates that TheRail will have a ridership of 116,000 (boardings) in 2030, about 10 years after the system is supposedly completed.

While TheRail is actually a fully elevated, steel-wheel-on-steel-rail heavy rail system, it is designed to fail by combining two poor choices:

(1) It is fully elevated which means it costs well over 5 times the typical light rail system.

(2) It does not use large, heavy rail style, high capacity trains, but smallish light rail trains.

These two choices make it a high cost and low capacity system.

Because of its low capacity, it is comparable to existing light rail systems. The table below includes all US light rail systems that (a) may be characterized as "modern" by having been developed after 1980, and (b) are over 8 miles of length. This comes to 11 comparable systems with route miles ranging from approximately 10 to 42 miles.

The average daily boardings of these 11 existing systems is 38,852 and the average route miles is 28. This yields 1,536 daily boardings per mile or 1,500 boardings per mile for a round number. (Remember we are talking about year 2030 and roughly 20% of TheRail’s users have not been borne yet.)

When one looks at statistics, it is advisable to remove the highest and lowest values and re-check the averages. By doing so for daily boardings and route miles, systems 3, 6 and 9 drop out. The resulting average daily boardings of the eight systems is 37,822 and the average route miles is 27. This yields 1,528 daily boardings per mile. This again rounds to 1,500 so this estimate is quite robust.

Using this estimate of 1,500 times the 20 miles of TheRail yields 30,000 daily boardings. Now let's give a huge break to Honolulu because of the H-1/H-2 congestion, the high cost of living and the higher average density (although high density does not apply west of Middle Street): Let's double this estimate to 60,000 boardings. This will be the likely maximum boardings of TheRail.

What's the City's estimate that FTA approved? 116,000 daily boardings, which is laughable.

Both Parsons Brinkerhoff and FTA received dozens of eggs on their face for the island heavy rail Tren Urbano in San Juan, Puerto Rico where they estimated 80,000 boardings on the opening year and they got 25,000 in 2006.

There is no lesson for PB, FTA and HART to learn. There is no accountability or penalties. They are all dedicated promoters of TheRail. Honolulu's ridership estimates simply prove that history (and unabashed deception) simply repeats itself.
