HONG KONG: China Railway Signal & Communication Corp, the country's largest builder of rail traffic control systems, plans an initial public offering of up to $2 billion in Hong Kong, reported on Wednesday, citing people familiar with the deal.

Citigroup, Morgan Stanley and UBS are working on the IPO, which is expected to take place in the second or third quarter of 2015.

The state-run company didn't immediately respond to an email request for comment on the IPO plans or to phone calls to its main phone number in Beijing.
