Biofuel bus-train-road Answered
The Guided Busway
Essentially, this is like a railway for buses- a narrow concrete "road" open only to modified buses, following the path of an old railway to link commuter destinations together. Supporters say it's more practical than a rail link (as buses can drive straight off the end into town roads), opponents say the concept is flawed and that building a traditional railway would be cheaper. The buses are apparently "100% biofuel powered", though I'm having a hard time finding out exactly where those biofuels come from.
The future of transportation, or greenwashed white elephant?
I thought I should update this in light of bassman's comments, and because of something I wrote last October:
"the busway is due to open in a few weeks (so by our bureaucracy time, make that spring 2010)"
Well, it's spring 2010 and this morning on the train to work I finally saw a bus on the busway. It was marked "not in service" and was populated by half a dozen men in high-vis jackets, so I assume it was a test run of some sort, but at least there is life on it. Maybe I'll be able to post more about it before 2011?
