(Adds background, details, share moves)

June 13 (Reuters) - British transport operator Go-Ahead GOG.L said on Monday it had received two separate takeover approaches at a price it planned to recommend to shareholders if the potential suitors tabled a firm offer, sending its shares nearly 20% higher.

The two bidders - Australia-based transport service provider Kelsian Group Ltd (KLS) , and a consortium of Australia's Kinetic Holding Company and Spain-based transport infrastructure management firm Globalvia Inversiones - have been given access for due diligence, the London-listed firm said.

Shares in the company climbed nearly 20% to 1,446 pence by 0854 GMT - hitting a more than one-year high after the news. Its market value stood at 522.4 million pounds ($638.16 million) as of Friday's close.

Go-Ahead, which runs more than 6,000 buses in England and Britain's largest passenger rail contract, becomes the latest UK transport takeover target after FirstGroup FGP.L and StageCoach SGC.L .

The proposals, whose values were not disclosed, have come weeks after the company said it planned to expand its transport operations and reinstate its pre-COVID-19 dividend policy after a months-long strategic review.
