I'm well aware of (and have personally suffered) all of that: BART's Oakland Wye delaying trains, suicide-by-train, the value of grade separations, and of Clem's Caltrain-HSR blog that I've been reading since the beginni

Fully on agree on trying to get costs down to Spanish-levels and other developed world costs, and building everywhere while saving money. But the reasons for the dysfunction are pretty straight forward: there is group of engineering consult

Caltrain electrification project is independent/notdependent on CAHSR and also not dependent on grade separation projects, which seem to be tackled individually/ad-hoc in partnership with the city it's in. Everything I'

I wish we had rail, including HSR, everywhere but the real world comes with financial constraints. While a Central Coast trunk alignment would be nice, any reasonable analysis indicates it really should be lower priority than the Central Va

I agree with your post thread. A lot of people uninitiated in railways think of HSR as an airplanes on rails. HSR =/= Airline. Trains have a number of advantages, one of which is a small time penalty for stopping at a station relative

CAHSR’s mainline is intended to be SF-LA via the Central Valley, and connect the major cities along the way. Some of those valley have around a 1m+ people or will grow to that over time, making them viable to connect. Think “pearls on a str

I've noticed this too in China and the B&R rail projects, and while it would be nice to have double stack containers, consider Chinese engineers are making a reasonable set of tradeoffs. China is moving more containers than anyone

There are overhead electric rail lines supporting double stack freight in the NEC USA, China, India, and possibly elsewhere. There are YouTube videos and images on web. AAR Plate H (20’ 2”) is the North American rail loading gauge for doubl

Indeed, Chicago and the Mississippi River is the dividing line in the North American rail network. UP and BNSF dominate western US, CSX and NS the eastern US, CN and CP dominate Canada, and large regionals like KCS, the Mexico side is simil

>> Ships < Trains < Trucks < Aircraft This is true by approximate order of cost, but it does not show how large the differences are. Trucking can be up to 10X, an order of magnitude, more expensive than train by unit of mass.

Great points about public vs private owned networks, private competition at “higher layers in the stack” of a publicly owned network, and building a durable political coalition around that. I’ve been on this train as it were for many years,
