Also, if your dates and/or times are flexible, check other trains.^
Without looking at the schedule, I'm just making these times up. The 1 PM train may have a different price than the 8 AM or 6 PM train! And the 6 PM train on the 12th may have a different fare then the 6 PM trains on the 11th or 13th!
And trains #422, #322 and #22 all may have different fares - even though they are the
SAME train! Likewise, trains #7, #27 and #807 may have different fares, but they are the
SAME train also!
