MPs have expressed concern over controversial plans for a freight terminal on green belt land.

Oliver Dowden and Anne Main, MPs for Hertsmere and St Albans, have written a joint letter questioning what provisions have been made for the large number of workmen and heavy equipment that will be needed to construct the terminal at the former Radlett Airfield in Park Street.

The works needed to accommodate workers and equipment were not included as part of the broad outline planning permission obtained for the terminal in 2014.

Mr Dowden said: “As I have said all along, one of the many problems with the rail freight terminal is that they will not be able to find workers for the site in the surrounding area.

“Workers will have to travel from London and Luton, further adding to the pressure on our roads.

“Segro, the terminal developer, promised it would provide adequate transport for workers but they it does not to have any plans to do so. This is yet another gaping hole in the planning process for this completely inappropriate rail freight terminal.”

The battle to build a new £300m rail freight terminal has been ongoing since 2007.

In 2014, Eric Pickles, the former Secretary of State for Communities and Local Government, allowed a second appeal brought by Helioslough Limited – the developers at the time – against the council’s refusal to grant planning permission.

Following the decision, the council lodged an appeal to the High Court, which it lost.

They appealed again, but High Court judges dismissed the appeal and the council admitted defeat.

Almost 1,000 people signed a second petition to stop the development in September.

The depot will be around 400 acres and as part of the planning considerations a public park, around 600 acres, must be created to replace the green belt land.
