I would say, the charge that you have an anti-rail bias is dismissed - due to a lack of evidence!

Any chance of a transcript?

Why? Was I mumbling that much?

Why was it unwise to comment about PRT? I thought your response was a measured response. You weren't exactly embracing it but you weren't blasting it big time either. Yes, the guideways would be the same visual issues that is raised with other aerial structures.

Speaking of PRT, I was having a discussion with a PRT advocate on a Linkedin group and he indicated that PRT can have the same carrying capacity as LRT. I suppose if you put out enough pods, have a decent speed and operate over a short distance that might be true, but I tend to be a bit skeptical of that claim. After all, it was a PRT advocate making the claim. Anyone have any independent verification of that claim??

I also liked your BART SFO extension analogy and yes, they have done a lot of experimenting with the service to figure out how it should operate. The SFO-Millbrae BART shuttle was a complete waste. Then they had trips go to SFO and then to Millbrae. Because it was reversing the trip, you had to have two operators so that made it a bit more complicated. So now they are operating one line directly to Millbrae and one line directly to SFO with no shuttle at all. If you want to go to SFO from Millbrae you now have to go to San Bruno, get off, cross the platform and board a SFO bound train. This has to rank among the most stupidest travel options around. I tried to raise the issue to both BART and the Bay Rail Alliance, which is a rail advoacy group for Caltrain, and no one seemed to care. Oh well, I tried!!


Discussing PRT in a speaking engagement is not dangerous--no danger of a horde of PRTistas getting wind of the talk and descending en masse on Metro headquarters to argue with you--at least not before your talk ends and everyone goes home.

But mentioning it here....


PRT is viable, already in operation, and an integral part of most cities transit systems. It is just called by another name - Taxi

True, but I was thinking of the proposed automated variety that doesn't charge per the mile... :)
