Cable Splicing

Last week’s post about six common uses for steel cables generated significant conversation and questions about the cables themselves. One question that was not asked, however, was how a company goes about splicing the two ends of a cable into one continuous loop.

I’m told this is one of the most impressive aspects of a cable system’s installation and is something I, myself have never witnessed. Only a handful of people worldwide are licensed to do this incredibly specialized operation. This multi-day operation involves a team of individuals untwisting tens of metres of steel cable and then re-twisting the two ends together at regular intervals in order to complete one single complete loop.

It is also this section of cable that is the most vulnerable to damage, thus the specialized nature of the operation.

For a great insight into this, check out Lift Wold’s cable splicing photo essay to see a cable splice, step-by-step.

Pretty impressive stuff.

Americans Want Public Transit (A Satire)

One of my favorite websites in the world is the satirical newspaper, The Onion. Its commentary is such a spot-on accurate depiction of how the world works, it’s oftentimes a more reliable source of news and commentary than our traditional sources.

An absolute favorite article (from 2000) is titled Report: 98 Percent of U.S.Commuters Favor Public Transportation For Others. Among the highlights:

  • “With traffic congestion, pollution, and oil shortages all getting worse, now is the time to shift to affordable, efficient public transportation,” APTA director Howard Collier said. “Fortunately, as this report shows, Americans have finally recognized the need for everyone else to do exactly that.”
  • Among these positives: the health benefits of getting fresh air while waiting at the bus stop, the chance to meet interesting people from a diverse array of low-paying service-sector jobs, and the opportunity to learn new languages by reading subway ads written in Spanish.
  • The APTA is kicking off a campaign to promote mass transit with the slogan, “Take The Bus… I’ll Be Glad You Did.”

Meanwhile, in March of this year Transportation For America announced: New Poll Shows Americans Strongly Support Public Transportation.

It’s easy to say you support public transit. After all, who wouldn’t? Even easier to take a poll and say people in general support public transit.

But the real question isn’t whether or not you support public transit. The question is will you ride public transit?

The Ten Day Traffic Jam

Last week, a variety of news outlets (Associated PressCBCNew York TimesThe Drudge Retort and dozens of others) reported on a massive 100 km long traffic jam outside Beijing, China. The jam lasted ten days and stretched into Inner Mongolia only to ‘vanish’ seemingly overnight.

Of all the reports on this story, the one that caught my eye was from The Globe & Mail. In the article, they quote the mayor of Beijing via government report saying “getting people out of their cars has not been easy. Last year the rate of people who took public transportation for their daily commute in Beijing was only 38 per cent.”

According to the article, Beijing’s road network is virtually over capacity or will be by 2015 and despite having the worst “commuter pain” of all major cities in the world, new car registrations are up 23.8% over last year.

And yet, Bejing has a massive public transportation system that includes subways, buses and suburban commuter lines.

In other words: Despite having an incredibly useful public transit system and ridiculously bad traffic congestion, transit is losing the battle for the hearts and minds of commuters. While it’s no where near as bad as in North American cities, it’s certainly surprising that transit gets such a small share.

Two months ago I wrote a post called Form vs. Function. In it, I questioned Jarrett Walker’s assertions (here, here and here) that function and ‘Usefulness’ (his word) are all that matter when trying to lure people into using transit. I argued that transit, as is currently designed, doesn’t create ridership as much as we might like to believe. Even cities with ‘Useful’ transit systems still do not attract the majority of commuters that the private automobile does.

In Beijing, we’re seeing that very phenomenon on display because mode choice isn’t always a function of logic or Usefulness, it’s also a function of emotion, ego and pleasure.

The private automobile, remember, is as much status symbol as it is a means of getting around. They are also undeniably more pleasant to ride than public transit. Public transit, after all, doesn’t even offer you a cup holder, let alone seat warmers, surround sound systems and GPS.

According to Jarrett’s Usefulness theory, people in Beijing should be streaming away from car ownership because car ownership is clearly not Useful – as evidenced by said 10 day traffic jam. In a city like Beijing, the private automobile doesn’t display Usefulness, instead it’s Uselessness personified.

And yet people are flocking to it.

Beijing disproves Jarrett’s Usefulness theory and suggests that something other than the harsh light of utilitarianism is necessary to lure people to transit. As I see it, it’s the design of public transit that matters. The quality of the ride matters as much if not more than the Usefulness of the system.

After all, the quality of a ride in a car is apparently so much better, tens of thousands of Beijing residents would rather sit in their private car in a 100 km long traffic jam than ride the train or bus. For those people (and the increasing number of car owners in Beijing), it’s not a matter of Usefulness or function, it’s a matter of form, style, comfort and pleasure.

Or maybe we’ll all just be saved by The Chinese Tunnel Bus™.

Iran To Build The Most Statistically Impossible Gondola

Payvand Iran News reports that Iran is to begin construction on the world’s longest gondola system in the city of Orumieh this Saturday. The system (or the report) is too strange for words.

The tourist system is to be 36 km long and would be made up of three separate sections. If the vehicles pass from one section to another without forcing customers to disembark, then, yes, this would be the longest such system in the world.

If however, passengers have to disembark at intermediary stations and assuming each section to be equal in length, then the Nörsjo Aerial Ropeway in Sweden is likely to hold onto the title of “world’s longest.”

That’s a somewhat minor quibble. The rest of the report, however, is pure bizarreness:

  • “2000 individuals can be moved per hour while staying in the gondola lift for 17 minutes.” Huh? What does that even mean?
  • The report says the vehicles would travel at 6 m/s (21.6 km/hr). That means the journey from end-to-end would last 1 hour, 40 minutes. Again: Where does this 17 minutes come from?
  • “The project needs 5 billion dollars and 120 thousand euro…” What?
  • 5 billion dollars… I’m hoping they mean Iranian currency.
  • 120 thousand euro… What?

One can only assume this is just stuff getting lost in translation. But in case it isn’t…

What?

Medellin Metrocable Victim of Collateral Damage

Colombia Reports is reporting that Medellin’s Metrocable Linea K has been suspended due to damage from gunfire.

It seems that recent economic troubles in Colombia coupled with increasing tensions between the La Agonia and La Divisa gangs exploded on Tuesday in a hail of bullets. The neighborhood of Santo Domingo (where Linea K exists) was essentially crippled by the warfare. Sixty people were arrested after authorities regained control of the area.

The Juan XIII Metrocable station and 3 gondolas were damaged. No word on when the transit line will re-open.

Medellin’s resurgence has been one of South America’s great feel-good stories. Let’s hope recent violence there is nothing more an aberration and not a sign of things to come.

Info Needed: Chongqing Cable Car

Somehow this one seems to have slipped under our collective radar:

Nick sends us a link to an urban cable transit system in Chongqing, China. Seems like an old Aerial Tram system with scant details.

Since The Gondola Project readers have been so good at drumming up information on little known systems, maybe you all would like to take a crack at this one . . .
