The downtown portions of Chicago's Blue Line[1] and Red Line[2] were primarily dug using tunnel boring machines in the 1940s. Here's a better view of the tunnels being not square[3].
Edit: infographic of various tunnels under Chicago, many of which are even deeper than these bored ones[4]

I suspect it's related to some patterns when reading books, like putting a bookmark below your current line and moving it down, or following your current position with your finger.
Looks like they used to have an online form a several years ago, but it went missing. Various blog/forum posts indicate that most people have had no luck getting any sort of response from Visa via mail.
They could do more to improve the standing room problem, which adds up quickly. My evening train is now perpetually 3-5 minutes late, which adds 10% to the runtime, due to the train in front being overcrowded. They are putting out new timetables for next month that they claim will improve this. Their fix is to move its departure time closer to the slow train in front, and add 3 minutes to the trip duration. Frustrating.
In a similar vein, it's not just foreign investors. It might also make sense to leave the grandparent's house empty while they are in the nursing home if you live further away. If the grandparents don't need to sell the house to pay for retirement, you'd probably come off cheaply enough to leave it empty, pay the property tax and minimal utilities, rather than risk having tenants.
I thought it was interesting how the tone changed on Schneier's blog.
There are 4 (edit: looks like 5) unused Metrolink cars sitting in the siding at 4th and King. I don't know why they aren't being used on some of the busier routes.
An unofficial blog about Caltrain and California HSR talks about one solution to the capacity problem and some non-solutions. I personally take it with a grain of salt, but it's still interesting: http://caltrain-hsr.blogspot.com/2013/02/the-virtues-of-widt...
