How the GMI Score works
Every operator is scored on a weighted set of factors, each normalized within its league so international giants and national incumbents compete fairly. Weights are public and versioned. National rail incumbents often carry a review-bias flag — their Trustpilot pages are complaint sinks, so we add an objective operational-performance factor rather than take a 1-star headline at face value.
