Consultations on the BLine for 41st and the Greenway
Thanks to Rick Jelfs of Transport Action BC for the heads up on two sets of consultations going on at present. This illustration comes from the City of Vancouver’s PDF of the Arbutus Greenway in its expected final form with a streetcar!
- TransLink is asking for public input on four new B-Line routes – 41st Ave (UBC – Joyce Stn); Fraser Hwy (Surrey Central – Langley); Lougheed Hwy (Coquitlam Central – Maple Ridge); Marine Drive (Dundarave – Phibbs Exchange). The 41st Ave. proposal includes the return of local trolley coach service along 41st Ave. More information at https://www.translink.ca/bline.
- Vancouver has a “proposed design concept” for the Arbutus Greenway at http://vancouver.ca/streets-transportation/arbutus-greenway.aspx.
I must admit I was a bit sceptical of the 41st Avenue B-Line until I saw what was actually proposed – which involves a considerable change to the current #41 – which would be cut back to Crown and would use trolleybuses – which is something that I have been pushing whenever anyone would listen for many years.
Trolleybuses aren’t used on the 41 right now, but the wires on 41st are used for training and relocating trolleys. Probably much less now that Oakridge OMC has been sold.
The current generation of hybrid Novabus, has a final electric drive – but no poles even though 600v is within easy reach.
The articulated buses used on the 43 and 49 that will be on the B Line
The short lived experiment with loaned battery buses from China (BYD). Another trial of different battery buses was recently announced. They will be able to charge along the route (100 Marine Drive) but again not using trolleypoles. All those pictures were taken by me along West 41st Avenue.
I am of course also pleased to see a cross North Shore B Line running through both West and North Vancouver. I was involved with the first groundbreaking bus service to cut through the iron curtain that used to separate transit on that side of the water. There is even talk of combining City and District in North Van which at that time was unthinkable! But I digress. Even if you can’t manage the open houses you can still do the surveys.
Batteries included: Network Rail begins on-track trials of prototype battery-powered train
‘What’s this got to do with transit in Metro Vancouver?’ you might be asking. Well, it’s a trial of a new technology that does actually have potential impact here.
Network Rail and its partners believe battery-powered trains could be used to bridge gaps in otherwise electrified parts of the network or be used on branch lines where it would not be cost effective to install overhead electrification equipment,
You can read the entire press release, if you are interested. A couple of important bits of information are missing: the weight of batteries and what they do to the power consumption of the train when it is running under the wires. The second bit there is probably one of the key determinants of whether this project goes on to production. There are many prototype tests: many of them have short lives or look very different by the time they get into production.
The technology is the interesting bit, because it does not necessarily need to be confined to trains. Vancouver has an extensive network of electric trolleybuses, but the wires do not always extend to useful destinations. It is very expensive to construct the overhead (back in 2004 I used to use the figure of $1m per kilometre for plain track – more for “special works” like switches and diamonds). So to add enough wire to get trolleybuses from say 41st at Crown to UBC is cost prohibitive.
The “new” trolleybuses – actually entering service at the end of 2006 – have much better batteries than the previous generation, but even so can only run at low speed and limited distances. And someone has to be stationed at each end of the gap to do the pole pulling. So battery power is for short distances and for temporary disruptions. Routes like the #7 Dunbar – Nanaimo have been running diesel buses under wires most of the way for at least a year by my observation. This new technology could see faster, longer operation on battery power for longer distances. This would both reduce the use of diesel – a worthy aim in itself – and cut costs. As long as someone comes up with a automated pole puller. Routes like the #9 could actually terminate somewhere useful, like Brentwood Mall, instead of the traditional loop at the city boundary. The #41 could run out to UBC electrically and use the wires for most of the route.
This is probably more likely than seeing CMBC put poles on hybrid buses to achieve the same objectives.
In other news
The draconian changes in drunk driving rules in BC have worked to reduce collisions and casualties. No mention is made of why this change in legislation was controversial in this UBC study, so it does not come across as an evenhanded or even objective assessment of the policy change. Were the fears of the restaurant/pub operators justified? Are there any civil liberties concerns about the presumption of innocence lost at the “sobriety checkpoint” or the absence of due process when the police impose penalties without judicial oversight? Or is the unspoken rule any life saved is worth any cost?
What holds energy tech back? The infernal battery
Thanks to Sightline again for the link to an AP article in the Seattle Times. It is a very useful, non-technical review of the lack of progress in battery technology. “It’s why electric cars aren’t clogging the roads” which is a useful bit of reality check against the optimism expressed by the report I looked at yesterday.
As for the electric car industry, lithium ion batteries have proved to have two major drawbacks: They are costly, and they do not allow automobiles to go far enough between rechargings. A123, a maker of lithium ion batteries for electric cars, went bankrupt last year because of poor demand and high costs after receiving a $249 million federal grant.
I know I have covered this ground before, but it is worth re-stating. What we want is the comfort and convenience of the car without its environmental impact. It is based on the mistaken idea that if we could get rid of the internal combustion engine – or the fossil fuel it now runs on – all would be well. And that is not true. The problems we have due to cars include urban sprawl, health impacts from that as well as the direct impacts of vehicle collisions (even if we can bring ourselves to trust computers to drive the cars for us), huge economic dependency of both societies and individuals from over-investment in a movement device that spends nearly all of its time stationary, congestion and delay. If every car was suddenly to become zero emission tomorrow, nearly all of the problems of motordom would remain to be solved.
it has conflicting functions. Its primary job is to store energy. But it’s also supposed to discharge power, lots of it, quickly. Those two jobs are at odds with each other.
“If you want high storage, you can’t get high power,” said M. Stanley Whittingham, director of the Northeast Center for Chemical Energy Storage. “People are expecting more than what’s possible.”
At this point I expected a diversion to fuel cells: mercifully that isn’t there – but again yesterday’s report was full of optimism about hydrogen. Which is not a fuel at all but simply a way of storing and transmitting electricity – and not a very good one at that. It is horrendously expensive and very inefficient – simply because hydrogen is the smallest molecule and thus extraordinarily hard to store.
That does not mean we cannot expand the use of electricity in transport – just that we will have to concentrate on technologies that we know work, even if they are not quite a perfect replacement for the convenience and mobility of the private car. What we need to convince ourselves about is that neither of those things is a project killer. We don’t actually need so much mobility if we only could redesign and retrofit our cities to be more accessible. If what we want was in easy reach by walking – or cycling – and both modes were safe and attractive – we will do a lot more of both, reducing both our carbon impacts and the size of our waistlines. For longer journeys, fixed route public transportation that is unhampered by single occupant vehicles can be readily powered by very long extension cords – trolleybuses, streetcars and trains. As long as these have adequate priority the expense of grade separation can be avoided. Yes, private cars will be delayed. Good. That improves the case for modal shift and saves lives.
I also think that by now somebody ought to have taken the step of putting a set of lightweight trolleypoles on the roof of a hybrid bus – or shoving a hybrid power plant into a trolleybus. Then we in Vancouver could see extensions of trolleybus routes to useful destinations – and redeployment of diesel buses to the suburbs. So the #41 to UBC gets converted, the #9 extended to Brentwood – and the inner set of “express bus” wires along Hastings get used for SFU services instead of being an historical anomaly of earlier faster trolley bus service to the PNE.
For one group, the use of lightweight cheaper batteries is already paying off handsomely. In general I do not think that electric bikes are such a great idea. For better health outcomes alone, I favour human power as much as possible. But we have an aging population. When you are young, you have time but no money. In middle age you have money but no time. Then, just when you have money and time, your knees give out. That is when a power assisted pushbike makes all kinds of sense.
So we can indeed reduce the use of oil (and other fossil fuels) in transportation – and it doesn’t require any kind of technological advances. We already have “good enough” technologies which are getting better. Information technology has done a great deal to reduce much of the frustrations inherent in using transit, and for facilitating things like bike shares and car shares which could be so effective in increasing its range and effectiveness if only they were integrated properly.
What is missing is not some whizzo battery – or personal rapid transit or a cheap fuel cell. It is political will and resources. And that has been the case for nearly all of the time I have been conscious of the issues – over fifty years! Conservatism – the power of the special interest group we refer to as “the elite” – the 1%. That is the root cause of the problem – however you decide to define the problem. Unaffordability of housing, traffic congestion, bad air quality, environmental impact, global warming. All of these issues are based on the incredible selfishness of a very small group of people. Many of who spend a great deal of time and money telling us how much they care about these issues but none of which ever seem to get solved. Even though the solutions have been staring us in the face all that time.
Aged trolleys sold to Argentine city
These trolleybuses are not going to be scrapped. They are now on their way to Mendoza, Argentina. Translink gets better than scrap value, Mendoza gets a really cheap bus: $2,300 each plus shipping costs.
Trolleybuses can last for a long time since we do not use much salt. The body is in fact the weakest part of the bus, especially since these were not designed as trolleybuses but adapted from a diesel design. The poles on the roof with their heavy load – they have big springs to keep them pressed up underneath the wires – do create stresses. The electrical components can last a long time. An electric motor can last 40 years or more – longer if rewound. Of course the electronic components will also last but technically become obsolete quite quickly. Toronto at one time simply rebodied old trolleybuses and kept them going.
I wonder how long it will be before some savvy travel agent starts selling package tours to trolleybus enthusiasts to visit their old friends “down where the moon is small”.
What I did on Sunday
There was a final trolleybus ride organised by TRAMS last Sunday. Jason Vanderhill was among those I shared the experience with and he has a wonderful set of images on flickr.
Mine – as seen on the Vancouver Metblog – were very ordinary.
