The spec may be a behemoth at 1500 pages, but the RFP explicitly allows for alternate designs & standards (including aluminum!) to cast the widest possible net of rolling stock platforms. SEPTA is leaving no stone unturned

I've done something that I don't do very often. I wrote a short, quick polemic post. It was prompted by a discussion in here.
It's about why I'm still skeptical about ALTO's HSR project and why there is no way around transparency in public projects.

This concise description is not stressed enough. With urban rail there are more benefit to apply quad tracks instead of continuously adapt bypass track designs on certain high-throughput corridors over longer distances. Even so when commuter rail and urban rail share the same corridor.
That's a good way to concisely describe the benefits of a quad-tracking project.

Bringing in HSR to city centers has always been a touchy subject, even for Chinese cities. Barring Shanghai and Beijing, many other Tier I/II cities first introduces HSR at a location 10-20km from the traditional center and then considers how to introduce it into the city center in the next wave.
One of the major controversial issues during the early planning of the italian HSR N-S spine, from the late 1980s to the late 1990s, was about how it would deal with cities.
We just mention it briefly in our paper, but I will dive into the case of Florence as I think it's particularly instructive.
