As part of the “blended” plan, Caltrain and CHSR will be sharing the same tracks and stations. It would be a no-brainer for trains to have compatible platforms, right? Indeed, staff from both agencies announced (just days ago) that they would be doing precisely that.
And yet someone at the CHSRA didn’t get that memo. In a spec published just yesterday, the HSR trains are to have a floor height of 1295 mm (51 inches). This spec will serve as the basis for a train procurement process that has now begun.
1295mm is incompatible with Caltrain requirements. It really makes no sense — other than being compatible with the NEC. Why are they trying to maintain backwards compatibility with a rail line thousands of miles away?
Besides the platform height, there are other problems with the HSR train spec. These “off-the-shelf” trains are supposed to comply with both Buy-America and Buy-California rules — even though there are no high-speed manufacturers in California or the rest of the country.
The spec also has a requirement for 220mph operating speeds. As noted by the Peer Review Group, 220mph is not needed until the entire SF-LA line is in service:
It may not be optimized to have all trains running at 350 Km/h, particularly those trains with several intermediate stops. Very high speed is only needed on a long distance range and/or when high-speed rail is competing with air.
The 2014 Business Plan optimistically predicts LA-SF route will not be in service until at least 2028. Realistically, it will be decades before LA-SF is in service. Until then, the CHSRA would be running a strictly regional service — and regional services do not require extremely expensive HSR trainsets.
