Dealing with bump and sway is mostly a matter of running a ballast cleaner/tamper/regulator along the track more regularly. Maybe replacing some rail. Unless the actual sub-foundation is bad; that gets really disruptive.
Much cheaper than trying to ease curves, gradients, structure clearance, or provide grade separation.
Right. But Caltrain has had multiple full shutdowns over the last couple of years during the catenary installation. If they aren’t able to maintain the tracks with that much shutdown time it’s worrying.
