At 5:55am, train A has traveled 30 miles East, while train B is reaching the station traveling West at 70mph. After one week and 23 hours, at 4:55am, they have traveled a total of (7*24 + 23)*130 = 24,830 miles away from each other, and are now only 71.47 miles apart heading directly toward each other on the opposite side of the Earth. Nearly 33 minutes later, at approximately 5:27:59.28am, the trains crash. I rounded to 5:28am.
