Details on the Amtrak data I'll track

I'll note the time the Amtrak train first started pulling out of the station for the start of the commute, and the time the train actually stopped at some interim stations. After each actual time I'll note the difference between the Amtrak scheduled times and my time; '+' meaning over and '-' meaning under the scheduled time, both in minutes.
