Mark Wyborn, Porterbrook’s designate Head of Freight Commercial, said: “I am very pleased to be joining market leader Porterbrook at this very exciting time for both railfreight and our industry.

“Porterbrook will support the ambitious growth plans of Freight Operating Companies by financing new and improved assets, tailored to market needs. These will allow our railfreight customers to play a greater part in the Green Recovery.”
