As shown in the April 1967 timetable, Canadian Pacific continued the domecar theme started in the October 1966 timetable, only with spring & summer pictures outside of the domes. With this one, that theme continues with new fall & winter photos. The April 1967 timetable also started using a highly simplified map in the centerfold reflecting the reduced number of Canadian Pacific branchline trains.
This timetable continues to use that simplified map. However, any reductions in trains happened before the April 1966 timetable, as this one seems to show all the same trains as in that one.
