These guides were prepared by Mr. Young's family to accompany and provide reports for the database printouts. Included in the guides is a car summary organized by car number, owner, purchase cost, weight, roof, type, builder, year built, and its history of owners. The car history report is organized by owner, the dates the car was acquired, building, first in service, accident history, left the division, etc., motor type and numbers, compressor type, and controller. The rosters give snapshots of the cars owned by the company in 1900, 1908, 1916, 1930, 1940, and 1948.
