There is a way that somebody was able to put different, more reliable main processors and gate driver controls in the HHP-8s to solve some of those problems. The same can be done with the HST. the problem still lies though in the fully integrated trainset, with all computer systems on LON and CIN networks where every single onboard machine reports over the CIN (Car internal network) to a CMU (Car monitoring unit) which runs on Linux off a 386 processor. The massive CMU could be replaced with a rasberry pi... only problem is that would not solve the issue of all the inputs and outputs, something would have to be made for that. Stuff could be done but in the end you still have a high speed bank vault.Right now, Alstom's Bombardier unit is rehabbing those MARC HHP-8's... and I think the main problem was cooling.

I can see where renovating the Acelas for CAHSR might look good compared to that, but it's a waste of money to even be installing catenary and substations until the extensions to LA and SF are funded, land acquired and actually under construction. 2033 is the target date, which on that particular project probably means 2040.If it would be a waste of money to install the overhead catenary system (OCS) before interconnecting LA & SF, why are they building the tracks now? The whole point of building in the Valley was to demonstrate an active HSR train to Californians as cheap as possible so they can convince taxpayers to borrow more money by selling more bonds in another new referendum.
