This still misses the point I'm trying to address here. Caltrain will go through the process for applying for it even if it's not necessary. Regardless of whether the rule is preempted, they will still use it as a justification for costly or otherwise poor solutions.

The rule doesn’t exist. I mean I can claim a rule exists that I have to follow that doesn’t (and people do it all the time) but if they do that they should be criticized heavily for it.
