Top 100 most overcrowded services analyzed by train length (October 7, 2025)
SOUTHEASTERN'S 5-CAR CRISIS
80.9%
avg loading on 5-car trains (14 services at 65-98%)
CHILTERN'S SHORT FLEET
88%
of fleet is 2-4 cars, fundamentally too small
THE MISMATCH
92.7%
loading on 10-car train shows some routes need 12+
Key Finding: Southeastern has 5-car trains running at 80.9% average loading (98% peak) while
also operating 10-12 car trains at 71-74% loading. This isn't a capacity shortage - it's misallocation.
Chiltern's problem is different: 88% of their fleet is 2-4 cars, so they can't reallocate even if they wanted to.
