Timetable - February 8, 1937

This timetable appears to be nearly identical to the one of a month and three days previous, except for the green tint on everything and the bus service on page 6. Purely to connect with train 7, The Aroostook Flyer, a bus would pick one up at Houlton and take you to Littleton, Monticello or Bridgewater, while the express skipped those spots and went straight to Mars Hill. It would seem that there was enough traffic to those three towns to justify the bus. 
In addition, there is now a Saturday only bus operating between Caribou, Presque Isle, Fort Fairfield and Limestone. It would seem that the bus service was seeing many changes as they grew and expanded the service.
