  1. Thank you for the link. Objective of this thread: comparison and discussion of the results of two studies (1, 2) I didn’t find a post dealing with critical and comparative analysis of the results from the following reports (1, 2). (1) The Trolleybus in Edmonton: A Step Toward Better Public Transit and a Cleaner Environment An Information and Materials Package Written by Kevin Brown Produced for the Edmonton Trolley Coalition Affiliated with the TBus Group May 2001 Part I: http://www.trolleycoalition.org/pdf/whitepaper1.pdf Part II: http://www.trolleycoalition.org/pdf/whitepaper2.pdf _____________________________________________ (2) Hybrid Diesel-Electric Bus / Trolley Bus Demonstration Project: Technical Comparison of In-Use Performance April 18, 2008 Dr. David Checkel Mechanical Engineering University of Alberta http://www.edmonton.ca/transit/bus_testing...tiveSummary.pdf

  3. Recall of an important old news ... Trolleys reach end of the line Council votes 7-6 to scrap electric vehicles to buy 47 hybrid buses Gordon Kent The Edmonton Journal Thursday, June 19, 2008 EDMONTON - One of North America's last trolley systems will be unplugged by 2010 after Edmonton councillors decided Wednesday to scrap the vehicles and buy 47 hybrid buses instead. The 7-6 vote pitted a group that wanted to keep the electric-powered trolleys as a hedge against rising oil prices against a majority swayed by reports indicating the city would pay an extra $100 million over 18 years to keep the fleet operating. The swing vote came from Coun. Linda Sloan, the only councillor who didn't express an opinion during the lengthy council meeting or at a public hearing last week. "It came down to my belief ... LRT is the system we put millions of dollars into," she said later. "We need to expand it. To divide our investment between trolleys and LRT, I don't think is a prudent use of resources. "I believe the LRT system should continue as the backbone of our transit system, and we couldn't invest in both." Coun. Amarjeet Sohi was concerned that spending money on trolleys would not add service in communities that have been waiting years to see improvements. Such a move might also make it harder for the city to push for increased transit grants, he said. "If we're not using money wisely and are not demonstrating we're using resources effectively, we will not be able to make an argument (for funding) to other levels of government." The debate over the future of the trolleys has come up repeatedly since the mid-1990s. Councillors voted in 2004 to keep the equipment until this year while alternatives were evaluated. But senior transportation officials were unanimous in their opinion that trolleys, running on expensive overhead wires along a small number of routes, are too costly and inefficient to retain. Just four of the 1,500 American transit systems still use the vehicles, and Vancouver is the only other Canadian city where they operate, transportation general manager Bob Boutilier said. Production of the machines peaked in 1948, he said. "Every dollar you spend on trolleys is money that's not being spent on other transit service and other transit technology." University of Alberta engineering professor David Checkel wrote a consultant's report indicating the vehicles cost four times more to run per kilometre than diesel or hybrid buses, while producing more total air pollution because they use electricity generated by burning coal. He accused his many critics of taking a "nostalgic" approach that doesn't reflect improvements in modern buses."I would rather see us spend money to put more buses on the streets so we can get more cars off the road," he said. But Coun. Don Iveson said the information provided didn't consider a variety of important factors, such as the impact of increased population density along trolley routes. "We need to look beyond a snapshot analysis," he said. Edmonton Transit will start next year to phase out its 40 trolleys, which were bought in 1982. They make up about three per cent of the city's total bus fleet. Councillors hope to use some of the money saved by cutting trolleys to help pay for a $270-million plan to increase transit ridership by 50 per cent over the next five years. gkent@thejournal.canwest.com HOW THEY VOTED For scrapping trolleys: Coun.

If not, what is the % of the energy produced by these plants and delivered to ETS trolleybus system ?

  17. I have just found the answers to my questions: Re: articulated trolley bus, New Flyer E60LFR (2007) from Vancouver. 1) The motor is equipped with IGBT (Insulated Gate Bipolar Transistor) (and not thyristors). 2) E60LFR has a pusher configuration. (not puller) Ref.: Vossloh Kiepe GmbH: http://www.vossloh-kiepe.com/files/Vancouver_fr.engl_507.pdf http://www.vossloh-kiepe.com/index.php?wai...497&pid=434 http://www.vossloh-kiepe.com/index.php?wai...30497&cid=8
  18. Hi ! Is there someone who can confirm (or deny) for the New Flyer artic these characteristics: E60LFR is equipped with thyristor converters E60LFR has a puller configuration Thanks in advance
  19. Hello ! Can you identity this bus: http://www.radio-canada.ca/regions/images/...ink_10ubc_n.jpg It looks like an Orion, what year and model ?
  20. The project is in its initial phase. In a second version, the project will certainly unveil more details. Undoubtedly, the implementation of the new tramway/LRS will bring a major restructuration of the bus lines (as the metro did in 1967).
