A TAC is the fee a Railway Undertaking (RU) —like a passenger or freight train company—pays to an Infrastructure Manager (IM) —the company that owns and maintains the tracks, signals, and stations (like Network Rail in the UK or DB Netz in Germany). 1 The primary goal of the calculation is to recover the costs of the infrastructure. Most modern charging systems, especially in Europe (based on EU directives), use a two-part tariff model . This model breaks the charge into two main pieces: 1. Variable Charges (The "Wear and Tear" Cost) 2 This is the core of the calculation and is designed to cover the direct marginal cost of your specific train running on the track. It answers the question: "What is...
