The results of the sensitivity analysis as being revealed in Table 1 show that Amtrak Rail will be able to achieve a fueling and servicing with less than 2.2% increase in the locomotive routing cost. Moreover, the company will be able to achieve a 100% fueling and servicing routing friendly, which will make the company to save several million of dollars yearly thereby assisting the company to enjoy profitability at the end of each fiscal year.

This project attempts to solve the problem facing Amtrak Rail. The project formulates the problems facing Amtrak Rail using mathematical model such as linear programming and integer programming. The results of the mathematical models have been able to provide optimal solutions to the Amtrak Rail problems. The optimal solutions reveal that Amtrak management needs to integrate operation research model into the planning to save millions of dollars from the costs of operations and thereby enjoy profitability at the end of the fiscal year.
