The company said the new service aims to boost the resilience of the UK supply chains.
The DP World operated service is scheduled every Saturday carrying cargo including fresh fruit, beverages, and consumer goods in less than 5 hours.
The train takes up to 120 lorries a week off the roads and cuts carbon emissions by up to 80 per cent according to the company.
DP World plans to increase the frequency of the train next year to ease motorway congestion, with a total of 300,000 trucks taken off UK roads each year.
“DP World is unique in offering customers a choice of deep-water entry and exit points to and from the UK,” said John Trenchard, UK Commercial & Supply Chain Director of DP World.
“This new rail service will make it even easier for our customers to switch volumes quickly and easily between the two locations, which means greater flexibility and choice.”
“After the disruption of recent years, shipping lines and cargo owners are looking for capacity, reliability, and growth opportunities. We are providing it, enabling customers to move goods smoothly and efficiently in and out of the UK and across their supply chains,” Trenchard added.
The company announced the start of construction at London Gateway’s new £350 million ($423 million) fourth berth last month, which will lift capacity by a third when it opens in 2024.
The construction project is supporting 1,000 jobs and the port-centric logistics park will employ a further 12,000 people upon completion in 2027.
The company has also earmarked a further £1 billion ($1.12 billion) of investment in the UK over the next 10 years.
In November, DP World teamed up with Emirates Development Bank (EDB), signing a Memorandum of Understanding (MoU) to provide small and medium-sized enterprises (SMEs) access to trade financing through DP World’s trade finance platform.
It includes a formal framework for EDB and DP World to provide SMEs with access to trade financing at competitive rates via DP World’s trade finance platform.
