The solution
In a November 2024 BBC report, DP World in Southampton says a scheme to transfer freight from road to rail cut 64,300 truck journeys in its first year. Since September 2023 it has imposed a £10 charge on every laden container arriving at the UK's third-largest terminal.
The money reduces the cost of rail journeys of less than 140 miles, with an incentive of £70 per container. Containers travelling longer distances by rail have the £10 levy refunded. Previously, journeys to giant Midlands distribution hubs were thought too short to be viable by train.
A year earlier only one container in five left Southampton docks by rail, and BBC says it is now close to one in three. DP World claims the incentive has cut carbon emissions by more than 17,000 tonnes in the year.
Why it worked
Short rail hauls are unprofitable for operators without help.
A flat charge on all containers spreads the cost and funds the rebate.
Longer rail trips are exempt from the levy, so they cost shippers nothing extra.
What can be applied
A small broad levy can pay for a large targeted incentive that moves a whole flow to a better mode.
Aftermath
BBC reports four new container train services were started, serving Birmingham, Cardiff, East Midlands Gateway and Doncaster, plus a second link to DP World's London Gateway terminal. The ambition is 40% rail share in 2026, and the incentive continues until the end of 2025. The emissions figure is DP World's own claim.
