Cable Transit In Edinburgh?

Please take the time to visit Maria Mysliborska’s wonderful Master’s Thesis Page. It’s a beautiful page that suggests how academic theses will likely be developed and submitted in the future.

Maria’s plan is an elegant redevelopment of Edinburgh’s derelict waterfront. Among the highlights of the plan are a local public transit circulator using (you guessed it) an urban gondola. Her unique configuration imagines a rectangular, closed-loop system. Does that mean a single line running in a single direction, or a dual system running in both directions? It’s hard to say.

Nevertheless, it makes for an inspiring read. Check it out.

Toys For Tourists

You can classify urban Cable Propelled Transit systems in three ways:

The first category are those lines that are integrated into public transit systems. These may be used by tourists, but tourists are not the target market; local weekday commuters are. The Portland Aerial Tram, Roosevelt Island Tram, Medellin Metrocable, Perugia MiniMetro and Caracas Metrocable, for example.

The second category are those lines that are clearly used for non-leisure purposes, but service a more specific subset of tourist and business traveller, both local and foreign. Airport people movers, the Innsbruck Hungerburgbahn and the Mandalay Bay Cable Car are excellent examples of these types of systems.

With this kind of promotional movie tie-in, how could the Mississippi Aerial River Transit not succeed?

The third and final category are Toys For Tourists (TFT) lines. These lines, more often than not, are never actually realized and if they are, rarely survive for very long. TFT lines are never integrated into the local transit network, typically have high (predicted) fares and exclusively target the tourism market.

The Windsor-Detroit Freedom Gondola; the Montreal Telecabine; the Camden-Philadelphia Skylink; the Baltimore Lift; and the terribly-named Mississippi Aerial River Transit system in New Orleans are sad reminders of how not to go about implementing Cable Propelled Transit.

None of the previously mentioned systems were transit. They were, instead, means to generate private sector profits by externalizing at least part (if not all) of the costs onto the public sector. They were rides.

The real shame of these systems was the hubris associated with them. Without fail, each imagined a huge increase in tourism due to the creation of the gondola itself. In other words, predicted revenues were based upon the increased number of tourists the systems’ promoters imagined the gondolas would cause, rather than on the actual number of tourists that actually visited the city.

For years Camden, New Jersey has been one of the poorest, most violent and dangerous cities in all of North America. Ditto Detroit. Ditto New Orleans. With the possible historical exception of New Orleans, how lush do you think the tourist market is in these cities? Do you want to travel there? Does the existence of a gondola change your mind?

The strength of the Portland Aerial Tram, the Roosevelt Island Tram, the Telluride Gondola and any other successful urban CPT system is that the primary users of the systems are locals, not tourists. Tourists should be considered gravy; a nice bit of additional revenue during off-peak hours. But the majority – the meat - of the users need to come from local demographics.

Why this phenomenon only seems to occur in urban, rather than rural/resort regions is a mystery to me, but it nevertheless seems to hold true.

Tiny Observations & Cable Propelled Transit

The Grindelwald First MDG system.

We can use ski lifts as transit!?!

That’s a Eureka Moment and one that’s been happening to the urban transit community for the last 10 years. It’s big, it’s profound and it’s exciting. It’s also unwieldily and awkward because too much has been left uncovered and left unsaid. There are too many questions, too many details. What about safety? Corners, can we turn corners? Can we have intermediary stations? Etc. Etc. Etc. All these things and more are still not a part of urban transit’s collective, general knowledge base.

Which brings me to a MDG system in the Swiss ski resort of Grindelwald First. The above picture is a piece of infrastructure incorporated into that system. Take a look at it and figure out what it is. If you’re familiar with CPT, you’ll have a few ideas. If not, you’ll have none. What is it? Is it a turning station? Is it an intermediary station? What is it!?!

If you guessed it’s a turning station, you’re halfway right. The other half of the answer is that it’s a high speed, slim-profile turning station. Turning stations are not typically slim, nor are they typically high-speed. This one is both and it was built in 1991.

I didn’t know such a thing as a high-speed, slim-profile turning station even existed until myself and some friends took a hike at Grindelwald last fall. I saw it and asked what’s that!?! This was not a discovery I earned, it was a discovery I fell backwards into purely by chance. It’s nothing more than a Tiny Observation, but one that has dramatic implications for the technology in urban environments. That it was discovered in a rural ski resort only complicates matters.

What if I’d not taken a hike to Grindelwald last fall? What if I hadn’t been lucky? Would we have known about this innovation? Hopefully, but who knows. I’ve read a report that says there are over 10,000 cable propelled systems throughout the world. What Tiny Observations are hidden in those 10,000?

For Cable Propelled Transit to find its way into mass acceptance as urban public transit, we need more Tiny Observations and we need more than just blind luck to find them. The Eureka Moment is all fine and good, but it’s the Tiny Observations that give shape and meaning to the discovery. They enable us to move from asking if we can use ski lifts as transit, to actually building ski lifts as transit.

Discovering we can use ski lifts as transit is only the beginning.

Definitions

How you define a problem determines how you solve it.

Most transit agencies, planners and governments tend to define an urban public transit problem as a decision between Roads and Rails:

Should we use buses, light rail/streetcars or subways?

It’s no surprise then when buses, light rail/streetcars or subways are the end result. That’s what happens when you define a problem from its middle, rather than from its beginning. You get mediocrity, the status quo and exactly what you expect. Better instead to start the discussion where the discussion starts:

How do we move the number of people we need to move through a given environment as quickly, cheaply, safely and efficiently as possible?

Define a problem from its beginning and you’re bound to get more than just Roads and Rails.

Optimism Bias & Ikea on a Saturday Morning

Optimism Bias is the economic concept whereby humans make forecasts, predictions, budgets and schedules that overestimate the positives and benefits while underestimating the negatives and the risks. It’s unconscious and well documented. It’s one of the major reasons public works, transit and infrastructure projects are perpetually over-budget and not-on-schedule.

For example:

This morning (a Saturday no less), my girlfriend and I decided to go to Ikea. How smart was this? Not very. Everything you need to know about the awful side of humanity you can learn from one trip to Ikea on a Saturday morning. And I know this.

I know there’s going to be traffic. I know it’s going to be at least an hour’s drive. I know there’s not going to be a parking spot less than 1 km from the front door. I know it’s going to take me 15 minutes to find a bathroom. I know the line up for $1 hot dogs is going to be longer than the night is dark. I know I’m going to get into a fight with my girlfriend. I know I’m going to confuse the Billy with the Expedit. I know I’m going to need an hour of advanced calculus lessons just to figure out the 17 different components I need to build a desk. I know I’ll have difficulty choosing between Birch and Maple. I know I’m going to add twelve things to my shopping cart only to remove seven of them two hours later. I know I’m going to do that twice. I know it’s going to take the 14 year old salesman 20 minutes to confirm that the item I require to prevent my bookshelf from falling over and injuring me is not in stock despite what the computer tells him. I know I’m not going to be able to read the measurements I took at home because I scribbled them on the back of a napkin. I know half the cash registers will be closed. I know I’m going to have to go to some other counter to place a special order. I know I’m going to spend twice what I had hoped because those tealights were just too good of a deal to pass up. I know it’s going to take 30 minutes (minimum) to figure out how to fit whatever I bought into the back of the car. I know I’m going to need to go back in the store to get rope to tie the trunk closed. I know I’m going to have to stop for gas because that’s just how far away Ikea is.I know it’s going to take me days to allen key together all this stuff. And I know I’m going to have to go back there the very next day to buy the legs that should’ve been included with my table but for some reason are sold separately.

I know all this. I know it like gospel. Ikea on a Saturday morning is like taking candy from strangers. You just don’t do it. Ikea on a Saturday morning is Ikea for an entire weekend. It’s a zero sum game. And yet despite knowing this, I wholeheartedly believed that we could get to Ikea and back with plenty of time to get a blog post up by lunch. Right, Steve, right.

So please accept my apologies for the lateness of this post. My optimism got the better of me.

The Gondola Revolution

The good people over at Fourstory.org asked me to write a piece on Medellin’s Metrocable and it went live yesterday. Check out The Gondola Revolution.

Special thanks to Tony Chavira for all his help and support. Please take some time to cruise Fourstory’s site, you’ll be well-rewarded.

Medellin/Caracas, Part 7

Two weeks ago I travelled to Medellin, Colombia and Caracas, Venezuela to tour five of the most important CPT systems in the world. This is Part 7 where I discuss the social mandate that underlies the Caracas Metocable. Image by Steven Dale.

If you’ve been paying attention, you’ve probably noticed something problematic about the Caracas Metrocable: The stations are enormous. We’re not talking about just “big” here. We’re talking about “big enough for Cirque du Soleil to perform in.”

This is because the stations themselves are not really stations at all. Whut? Exactly.

In actuality, the Caracas Metrocable stations are full-service community centres with multiple neighborhood facilities all under one roof including a Cable Propelled Transit line. Most of these facilities are not yet complete and as such the stations have an eery empty quality thus far. The plan, however, is to have gymnasiums, markets, dental offices, police stations, medical clinics, theatres, libraries and all other manner of social services located within the 5 stations united by the Metrocable.

The idea is to have each station host one or two such facilities. As each station is linked to the other via Metrocable, those within the poor barrios can travel quickly and cheaply between those services in a way that simply would not have been possible before the Metrocable. When you consider this component of the plan, the Metrocable is less a transit line and more the connective tissue that holds together a network of social services.

Whether or not you agree with the political ideology behind Hugo Chavez’s plan, you have to admit it’s bold and unique. It’s also costly. The price of the Metrocable including stations/community centres has been reported as $265 million USD and I’ve heard numbers as high as $300 million USD. Considering the system is only 1.8 kilometers long, you could practically build a subway for that price.

The price of the gondola system, however, was modest. Everything necessary for the gondola system (the “electro-mechanical” cost in industry-speak) was only $18 million USD.

Consider that for a moment: Only 6-7 % of the total cost of the Metrocable went to the transit system and infrastructure itself. The rest was spent on the stations/community centres and land expropriation costs.

I want to state this plainly so that no one opposed to the concept of cable transit can use Caracas as an example of how expensive the technology is: The Caracas Metrocable did not cost $300 million. It cost $18 million. The additional monies spent were on community centre facilities and land expropriation costs that were separate from the transit system itself.

Once again (because the internet is great at taking people out of context): The Caracas Metrocable did not cost $300 million. It cost $18 million. The additional monies spent were on community centre facilities and land expropriation costs that were separate from the transit system itself.

Should some of those additional monies be allocated to station costs? Yes, but not the vast majority of it. The Medellin Metrocable (which uses similar MDG technology) Linea K cost $26 million USD in 2006; that included 1.8 kms of length and 4 stations. Linea J cost $50 million USD in 2008; that included 2.7 km and 4 stations. Linea L cost $25 million USD in 2010; that included 4.8 km and 2 stations. It would be fair to allocate an additional $10 – $20 million dollars to the cost of the Metrocable itself, but no more than that.

Perched high atop hills, the Caracas Metrocable stations are one small component of a much bigger network of community centres and social services. Image by Steven Dale

As a social experiment, it will be interesting to see how the Caracas Metrocable pans out. I, for one, am hopeful. Caracas needs these kinds of services, particularly in the barrios. One thing, however, I’m not certain of is the overt social message of the Metrocable. Many cabins are adorned with single word imperatives suggesting qualities which those in the barrio should aspire to and exemplify:

Sacrificio . . . Moral . . . Libertad . . . Equidad . . . Humanismo . . . Amor . . .

It’s an odd design choice that has nothing to do with the technology itself. But as one rides the Metrocable or sees them glide overhead, one can’t escape this blatant messaging. Granted, it’s hard to argue with the message: Sacrifice, Morals, Liberty, Equality, Humanity, Love. But at the same time, is it a transit agencies job to suggest how to behave? Maybe, maybe not.

In the western world we’re used to being told how to ride our transit. Hold the handrail. Exit by the rear doors. Don’t spit. Don’t litter. Give up your seat for the elderly. Mind the gap. These instructions transit agencies force upon us are nothing more than the practical application of the emotional instructions the Caracas Metrocable forces upon its riders.

Maybe we wouldn’t need so many rules and instructions in our transit systems if we simply had signs that read “Love” or “Equality.” Or not, I don’t know. It’s something I’ve wrestled with a lot since seeing it. Is it propaganda? No. But it veers pretty close to it and that’s what makes me uncomfortable. The message plays so blatantly upon emotions and that’s problematic. But at the same time, the sweet naiveté of the gesture is charming enough, innocent enough to catch even the most cynical observer off-guard.

I honestly don’t know. I’d love to know what everyone else thinks about this matter. Take a look at the images below and form your own opinion: Are the messages on the Caracas Metrocable propaganda? Are they amusing and pleasant? Are they harmless? Are they dangerous? What do you think?
