Just select a date (or date range) and two stations, and you'll get a personalized timetable showing you all the available travel options, whether it be train, connecting bus or a combination of the two.
The academic timetable lists classes offered in a particular term. You will use it to choose classes, create your schedule and determine where your classes are being held and who is teaching them.
You can view the timetable by both term and subject. For example, if you are planning to take an English class in the Fall term, you would select the Fall term from the top of the page, and then select English from the subject listing menu. This will display all of the English classes being offered in the Fall term.
