NPV Analysis of a UK Rail Franchise Capital Decision
This paper evaluates whether South Coast Railway should accept a five-year UK government franchise to operate a high-speed commuter rail service from 2018 to 2022. Using net present value (NPV) as the primary capital budgeting tool, the analysis calculates the firm's weighted average cost of capital (WACC) via the Capital Asset Pricing Model (CAPM) and discounts all incremental project cash flows. The results show that the project barely breaks even, yielding a slightly negative NPV and failing to meet South Coast's investment criteria. The paper also examines the impact of post-Brexit sterling depreciation on the euro-denominated train purchase and concludes that foreign exchange risk further undermines project viability.

What makes this paper effective
- The paper walks through each step of the financial analysis sequentially — from method selection to WACC calculation to incremental cash flow modeling — making the logic transparent and easy to follow.
- It justifies the choice of NPV over competing methods (IRR, payback period) with clear conceptual reasoning, demonstrating analytical depth rather than simply applying formulas.
- The paper integrates real-world context (Brexit, sterling depreciation) into a quantitative framework, showing how macroeconomic events affect project viability.
Key academic technique demonstrated
The paper demonstrates step-by-step quantitative financial reasoning: it derives each input variable (bond yield, beta, risk-free rate, tax shield) from first principles before assembling them into the WACC formula and applying the result as a discount rate. This structured build-up from components to conclusion is a hallmark of rigorous capital budgeting analysis.
Structure breakdown
The paper opens with a brief framing of the franchise decision, then moves through methodology (why NPV is preferred), calculation of the discount rate (WACC via CAPM), modeling of incremental cash flows and NPV results, analysis of foreign exchange risk, and a summary conclusion. Each section feeds directly into the next, creating a cohesive analytical chain from problem statement to recommendation.
Introduction and Decision Overview
South Coast Railway is evaluating a proposal for a five-year franchise from the UK government. This proposal would involve operating a high-speed commuter rail service from 2018 to 2022. The following report examines the financials relating to this decision and the decision-making heuristic used to evaluate it.
Capital Budgeting Methods: NPV, IRR, and Payback Period
The decision at hand is essentially a capital budgeting decision. There are several different ways to evaluate such a decision. The most common is the net present value (NPV) technique. This method relies on discounted future cash flows. The principle behind discounted cash flows is that money earned today can be reinvested, and because of that, a pound earned in the future is inherently worth less than a pound earned today. The value of future money decreases over time. The NPV method discounts those future cash flows back to present value and compares them with the initial cash outlay (Investopedia, 2016). The basic decision-making heuristic for NPV is that a project with an NPV above zero should be undertaken, as such a project increases the value of the company. It is assumed that the nature of the project in operational terms is secondary — a business exists to earn positive returns for shareholders.
A similar method is internal rate of return (IRR), which also compares discounted future cash flows to the present-day outlay. The mathematics behind IRR are the same as for NPV, but the value is expressed as a rate of return. Any return above zero reflects a project that has a positive value. The reason a company should generally prefer NPV over IRR is that organisations have fixed amounts of capital available to invest and must sometimes choose between competing projects. In such cases, the option that adds the most absolute value to shareholders — not merely the highest percentage rate of return — is preferred. A high rate of return on a small investment is worth less in actual wealth terms than a lower rate of return on a larger total investment. This is why NPV is superior to IRR when the firm must choose between two positive but mutually exclusive options.
Payback period is another common method for evaluating capital budgeting projects. This approach does not account for the discounted value of future cash flows; rather, it assumes that shareholders want to recover their investment as quickly as possible, and that managers prefer early break-even as a form of risk management. The reason payback period is inferior to net present value is that it ignores all cash flows occurring after the payback point. A project whose payoff is weighted towards later years may ultimately add more value to the organisation, yet it would not be selected in a mutually exclusive comparison under the payback method. The methodology best suited for enhancing shareholder wealth remains net present value, whatever other practical benefits the alternative methods may offer (Gallo, 2014).
