Las Vegas to Victorvile for the “high speed” train will not reduce north bound traffic into, or south bound traffic from Victorville on the I-15 (already a cummuter suburb for workers with jobs south of Cajon Pass).
I-15 along the segments between Cal-60, I-10 & I-210 northbound up & over, and south bound down from Cajon pass are already parking lots at various times of the day & week. It will only get worse, as additional So. Cal. travelers try to use the Victorville train connection to Vegas. Their additions to the traffic are likely to defeat possible time saved between Victorville and Vegas.
And Cajon Pass and it’s single main highway, I-15, could only be offset/bypassed by So.Cal. travelers west of the Inland Empire taking the I-5 north out of San Fernando, getting off below Santa Clarita at Cal. Rt-14, then taking Rt-14 north to Palmdale, to connect to Rt-138/18 over to Victorville. Neither are Interstate grade roads and the additional miles makes that detour not a likely choice for anyone.
That leaves a “high speed” rail line likely to make So.Cal. I-15 traffic worse than the “horrible” state many between Victorville and south of Cajon Pass already see it as.
I think the whole venture will turn out to be a fiancial boondoggle. Another “high speed” train to nowhere.
A "boondoggle" requires the presence of government money. Fortress Capital proposes to do this the traditional capitalist way. It may succeed or it may fail. Failure is a great teacher.
