MAX BRT Posted January 16, 2018 Report Share Posted January 16, 2018 There is a photo of a 35 foot Catalyst here: http://dartdallas.dart.org/2018/01/10/dart-demos-new-proterra-zero-emission-all-electric-buses/ Rare bus, and fairly soon there will be 7 in Dallas. I don't know if Proterra will make this a demo they keep, or if it will be one of the 7 that goes to DART. Link to comment Share on other sites More sharing options...

Hasn't hit service yet but it's been doing testing from photos I've seen. 1 1 Link to comment Share on other sites More sharing options...

MVTArider Posted February 2, 2018 Report Share Posted February 2, 2018 One of Proterra's Catalyst E2 units is currently in town touring with the MVTA: https://www.mvta.com/news/minnesota-valley-transit-authority-taps-proterra-for-big-game-week/ I was able to catch a ride on it on the 403 express shuttle service, it seemed to do well with the freeway. I think it was going about 60-65mph on the Hwy 77 portion. Of course a lot of cars whizzed by like we were standing still as everyone likes to go 70-80 on 77 Â I'm just assuming it's a 2017 since it looked fairly new and I didn't see it at the APTA Expo. (IIRC someone said they were building another E2 demo) It was being operated as a regular bus so didn't want to pester the operator about any technical details. Obligatory photos: Â Â I also posted a if anyone's interested. 3 Link to comment Share on other sites More sharing options...
WMATAC40LF Posted February 2, 2018 Report Share Posted February 2, 2018 I thought I'd mention that DC Circulator's 14 40' Catalyst buses (3001-3014) have all arrived on property now. If all goes well, they should enter service sometime this spring. 2 Link to comment Share on other sites More sharing options...

MAX BRT Posted March 26, 2018 Report Share Posted March 26, 2018 Proterra touts one-dollar-per-mile savings at Clemson Area Transit. (Transit buses in the USA routinely cover 500,000 miles during their lifetimes) "Even with the first version of the bus with all its additional initial engineering issues, they were still seeing a dollar per mile maintenance savings, which is huge," Saunders said. "As we've progressed with the technology, those savings will be even larger."

I believe it was a low steady speed record breaking attempt, not even trying to mimic a typical transit bus stop and go route in this case. But they made their point.  1 Link to comment Share on other sites More sharing options...

But again, I question many things that weren't mentioned. It was very obviously done in a lab environment, with ideal conditions. I'd be interested to see what that range is like with a crushload, in traffic, on a hot day in the summer with the AC on full blast. Or in the winter, with cold weather and deep snow. What about highway routes, where the motor would be using up more juice than at city traffic-congested ones? These records are all fine and well, and sure, Proterra did make somewhat of a point (to which I applaud), but I want to see real world conditions. And again, CFRP ain't cheap. I'm not sure too many agencies will be happy about paying the bill for patching up damaged carbon panels with more carbon. ____ This whole record thing reminds me of when a similar record was set by a Model S: https://futurism.com/a-tesla-just-drove-a-record-breaking-900-kilometers-on-a-single-charge/ 900kms, but at what speed? 1 Link to comment Share on other sites More sharing options...

Good qestions to ask! Regarding the Proterra composite body, I recall reading an internal LA Metro document that indicated they were happy with their Composite buses and were disappointed when they couldn't get more after NABI/NFI discontinued that line. I expect LA Metro to look closely at Proterra buses. Here is a video from the Proterra website, about repairing their bus bodies. https://www.proterra.com/technology/bus-body/ Link to comment Share on other sites More sharing options...

Bus_Medic Posted April 9, 2018 Report Share Posted April 9, 2018 Vague marketing claptrap. Any carbon fiber in there would be used sparingly in strategic points. Also makes chassis electrical design tricky as you can’t use a chassis ground in the conventional automotive practice. Link to comment Share on other sites More sharing options...

MAX BRT Posted April 10, 2018 Report Share Posted April 10, 2018 This Proterra long-range bus in the real world (Foothill Transit) has a listed range of 254 miles. Of course that will vary depending on driver skill and the conditions, especially ambient temperature and average speed of the bus. But ambient temperature doesn't vary so much in suburban LA--compared to say Fargo or Winnipeg. https://la.streetsblog.org/2017/11/03/foothill-transit-launches-new-long-range-proterra-electric-bus-service-today/ The Foothill Transit bus was launched last year. Currently, Proterra says it can already provide even more range: https://www.proterra.com/performance/range/ Link to comment Share on other sites More sharing options...
