Honolulu Rail’s New $27 Million Safety Feature to Avert Track Fatalities
Disturbing surveillance greeted board members of the Honolulu Authority of Rapid Transportation today.
In one clip a mother in Australia loses control of her infant鈥檚 stroller on an elevated platform’s edge and it falls into the train pit. A second later, she clutches her head in horror as the train rolls into the station and over the stroller.
Fortunately the six-month-old boy was fine. He鈥檇 fallen off the stroller and between the tracks as the train passed over his head. The terrifying sequence brought gasps to HART鈥檚 Joint Finance and Project Oversight Committee meeting.
It also seemed to serve its purpose. HART CEO and Executive Director Dan Grabauskas was able to convince the board to unanimously approve a $27.1 million change order to purchase and install platform screen gates at Honolulu鈥檚 21 planned train stations.
The safety feature seems like a no-brainer for the $5.26 billion project, which includes a 20-mile elevated railway that will run from East Kapolei to Ala Moana Center.
The sliding glass doors are designed to prevent riders from falling, jumping or being pushed onto the tracks where they can be hit by an oncoming train.

鈥淭he point is it鈥檚 not terribly difficult to find these videos,鈥 Grabauskas told the board. 鈥淯nfortunately, people falling into the pits is not an unusual occurrence.鈥
What is unusual is that HART had initially planned to install the platform screen gates long ago. The devices were included in project designs and schematics, and even appeared in certain artistic renderings.
But for whatever reason 鈥 officials can鈥檛 say 鈥 the gates were left out of the rail budget, meaning the $27.1 million is an extra cost that will dip into the project鈥檚 nearly $650 million contingency fund.
Had the HART board decided against the screen gates, the project would have proceeded with a $5.5 million fall detection sensor system that notifies the rail cars to stop trains when someone or something is on the tracks.
But as Grabauskas and others from HART explained, this system isn鈥檛 foolproof. A large bird, floating newspapers and other debris can set off one of the sensors, stopping the train cars and causing an unnecessary delay.
The trains also can鈥檛 stop in an instant. If someone fell at the same time that a train car reached their station, it might be too late.
Then again, it might not.
As for cost, the $27.1 million is small when compared to the overall contingency. But more costs are on the way.
The rail system doesn鈥檛 include back-up electricity should the power go out, and HART is looking at various options that could have wide-ranging price tags.
One option Grabauskas has discussed in the past is a regenerative braking system similar to those used in electric and hybrid vehicles that store energy when the brakes are applied. On the other end of that spectrum is simply buying diesel generators. No cost estimates have been released on either option.
There鈥檚 also the matter of paying additional delay claims to contractors who have been idle for more than a year as a result of a Hawaii Supreme Court ruling that halted construction in August 2012.
Although HART expects to resume construction on Sept. 16, the estimated cost of the delay .
HART also must negotiate with contractors over other delays caused when the City and County of Honolulu issued notices to proceed on construction before the work could legally take place.
Grabauskas wouldn鈥檛 provide an estimate on how much those delay claims will cost the project, but said he hopes to have the matter resolved within the next month or two.
