MADRID/BUDAPEST, Feb 8 (Reuters) - Spain's stock market regulator on Thursday suspended trading in shares of train maker Talgo after local media outlet El Confidencial reported that Hungary's Magyar Vagon planned to take over the company, causing the stock to soar.

The shares were last up 9.4% at 4.78 euros ($5.14) each on Thursday before they were suspended, pending disclosure of relevant information by Talgo.

Magyar Vagon declined to comment.

As of Wednesday's close, Talgo's market valuation was 551 million euros. It was listed on the Madrid stock market in May 2015 at a valuation of 1.25 billion euros.

Talgo had said in November an unidentified group was planning to offer 5 euros per Talgo share. Private equity fund Trilantic is Talgo's main shareholder.

Neither Talgo nor Trilantic immediately responded to requests for comment. ($1 = 0.9298 euros) (Reporting by Inti Landauro and David Latona in Madrid, Boldizsar Gyori in Budapest; Editing by Catarina Demony and Emelia Sithole-Matarise)
