Arriva, the bus and train operator with operations in London, Madrid and Lisbon, has been boosted by several successful contract bids and its strong appetite for acquisitions, buoying revenues across all the group’s divisions, the company said.

“While no business is wholly immune from current economic uncertainties, the group’s diversified nature, with bus and rail operations in 12 countries, a £12bn order book, and more than 60 per cent of revenues from government contracts, gives it a high degree of resilience and stability,” Arriva said in a statement on Tuesday.
