Subject files and documents relating to records of purchasing and maintaining rail cars, and to buildings and bridges construction and repair. Statements of Car Purchases are price lists of different cars, in reverse chronological order. Sundry subject files include New Buildings in Lexington, Mississippi (correspondence about a new dept at Wilson's Crossing), Chicago Memorial Hospital Right of Way issues (building a retaining wall), and Bridge repair at Manchac, Louisiana. The Historical and Current Record of Passenger Cars is a card file of IC cars, filed numerically by Car number. Series 1100 and 1200 cars are Suburban Motor cars, built between 1926-1929; Series 1300 and 1400 cars are Suburban Trailer cars, built between 1921-1929. The back of each card has repair information about the car, which ends at 1970. Each card lists the general description and dimensions (interior and exterior), type of truck, type and brand of hardware (wheels, couplers, hand brake, etc.), lighting and electrical system, seating, plumbing, interior and ceiling finish color, and seating upholstery. Some cards in the series are lacking.
