RAIL
Diesel Multiple Unit Fleet
A passenger rail application comparing fuel use and operating speed across normal service duty.
COMMERCIAL RAIL
HEADLINE RESULT-8.2% fuel / +4.6% speed
IDENTITYAnonymised commercial or independent study
STATUSPublic engineering summary
TEST METHOD
Measure the work, not the fuel alone.
Route-level fuel and speed comparison with operating context and service conditions retained.
ENGINEERING OUTCOME
Lower fuel use occurred alongside higher average speed, improving the work delivered per unit of fuel.
The public page presents the result at summary level. Supporting raw data, confidential client records and detailed engineering reports remain controlled.
