July 27 More Testing, More Pain. Very early on Friday, July 20 my wife, cat, and I were blasted awake by the sound of a train horn...Possibly this is simulating 15 minute service-I will let you know. Testing will ramp up to as many as six trains every 15 to 30 minutes between 3:30 AM through 1:00 AM the following day, approximating the regular daily service schedule. The horns are the pain, the gain is this necessary step to our finally riding the train. The horns will go silent with Quiet Zones, soon after revenue service starts, when approved by the Feds.
