Given the scope of each project, what other costs and/or benefits might not be fully captured in the tables above? That is, a cost and/or benefit that might not be accurately reduced to dollar terms.

Extracted text: The Mayor of Chicago is considering two rail transportation projects that you have been asked to evaluate. The first project is for locomotive modifications to improve fuel efficiency across the Chicago regional freight rail network. The project benefits come from fuel cost savings. The second investment project is for Chicago passenger rail infrastructure enhancements such as adding second set of tracks at congested network locations. The Mayor assumes this increased capacity will boost ticket and pass sales and those benefits are shown below. Both projects would provide benefit to the city for the next 30 years. Based upon the level of investment risk, the city Treasurer has suggested that financing could be secured at an annual rate of 7%. A number of alternatives have been developed for each project. The lump sum of the initial cash outlay and the ongoing monthly benefits have been estimated for each alternative and are shown in the following tables: Freight Rail Network Monthly Benefit ($K) Investment Alternative (SK) F0* 3,000 6,000 9,000 12,000 24.95 56.56 79.84 89.82 F1 F2 F3 F4 Passenger Rail Network Investment Monthly Benefit ($K) Alternative |($K) PO* 3,000 6,000 9,000 12,000 29.94 P1 P2 P3 P4 51.56 66.53 73.18 FO* and PO* are the "do-nothing" alternatives for the Freight and Passenger Networks respectively. For parts a, b, and c consider only the costs and benefits that have been converted to dollar terms.
