Expert panel to discuss light rail option for Honolulu

Three transit experts will take part in a panel next Friday afternoon to address the feasibility of shifting to street level light rail for the next leg of Honolulu’s rail system from Middle Street through downtown Honolulu.

Public Forum on Rail
Option 2A: Street Level Rail from Middle Street

Friday, July 14, 4-6 pm
State Capitol Auditorium
Presented by Salvage the Rail

Topics to be discussed include:

• The world–wide revolution in light rail (street-level and elevated)

• Changes necessary to convert HART stations for low-platform rail cars to allow street level operation after Middle Street

•Creating a true urban transit system incorporating pedestrian-friendly neighborhood design with street-level rail

• The cost savings of such a system.

• The ability to complete the downtown segment within existing budget (without GET surcharge extensions or other new funding mechanisms).

Visit the “Salvage the Rail” website for more information, including brief professional biographies of three transit experts who will take part, as well as other background information on the light rail option.

The website includes an interesting section on “Myths & Facts”. Here are just two.

Myth: Street level rail would require the digging of a 4-8 foot trench 30 feet wide and huge construction impacts downtown.

Fact: To lay a set of tracks construction would be 14 inches deep by 8 feet wide, which is the same depth as normal road construction. This would not require purchase of any additional land. Existing streets could be used. Because these streets have already been excavated, the issue of new archeological finds is not applicable. Street level rail stations are not bigger than a bus stop, requiring only a canopy for rain shelter and small ticket machine on an existing sidewalk.

In contrast, building elevated rail through downtown Honolulu would create enormous construction impacts since entire roadways will need to be cut open to pour underground spread foundations to support the weight of the elevated guideway. Constructing the football-field sized stations planned for elevated rail would create immense disruption to nearby structures, traffic and businesses downtown.

Myth: Street level rail will be slowed to the speed of automobile traffic.

Fact: The Middle Street-to-Downtown segment would be slower by 2-3 minutes (depending on length of final route). Signal synchronization can be used so that the street level trains can maintain 30-mile-per-hour speed through downtown, nearly the same speed as elevated rail. Managed lanes (for trains and buses only) keep trains running independent of automobile traffic speeds, and also greatly increase safety.

With a special legislative session now scheduled to consider additional rail funding, this discussion is even more relevant than ever.

The Amazon-Whole Foods future

As soon as it was announced that Amazon is taking over Whole Foods, investors quickly bet against other retailers. Walmart, Costco, and Kroger stock lost nearly $19 billion (yes, with a ‘B’) in value last Friday.

Since we now live near a Whole Foods store, I’m interested in how this is going to play out and how it will affect us as consumers.

I’m a bit puzzled by the immediate financial hit to brands like Costco.

Is it really times to give up that Costco membership? I don’t think so.

At the end of 2016, Whole Foods had 431 stores and had scaled back new store openings, while Costco had 727 locations.

Costco boasted about 85 million members. Amazon Prime numbers, the closest comparison, are secret, but estimated somewhere between 54 million and 80 million (a number that reportedly includes trial memberships and student members).

Up until now, Costco seems to have competed effectively with Amazon in areas where they overlap, such as electronics and apparel, so I’m not convinced this is necessarily going to be a slam-dunk for Amazon to pull off.

Amazon also has the daunting task of digesting Whole Foods without undermining the things that the WF brand stands for. Or, perhaps, they think that doesn’t matter.

Then today I read a fascinating article, “Amazon’s new customer,” at stratechery.com.

It’s a very perceptive analysis of Amazon’s approach and well worth pondering.

And now I’m not sure what to think!

A great example of sleuthing using social media

I love to learn new investigative approaches, so was fascinated by this description of digging through social media to track a person’s “hidden” account (“This Is Almost Certainly James Comey’s Twitter Account“). The article by Ashley Feinberg appeared on Gizmodo a couple of weeks ago.

In just four hours, and with minimal clues, the author was able to follow thin threads back to Comey’s previously anonymous account.

It took a bit of research into Comey’s background and personal life, then combing social media for accounts of family members, then some tricks based on idiosyncrasies of specific sites.

Anyway, it’s an example of great sleuthing, and a very good read.

When drones invade your personal space…

A friend recently posted this on Facebook.

It’s something that’s becoming a more frequent issue as this technology is quickly adopted.

What do you think?

He wrote:

drones. What is the protocol for dealing with a drone hovering outside one’s bedroom? M heard the whine and there were flashing green and red lights. We have power lines on two sides of the house so the pilot must have been more competent than ethical.

We don’t have a shotgun. Alternatives?

Hmmmm. What are the alternatives? Suggestions?
