The owners of rail freight operators Globaltrans and NefteTransService are in talks on a merger that would create a business with sales of $2.7 billion and a 10 percent share of the Russian market, industry sources told Reuters.

"They started (talks) several months ago and have been unable to agree on pricing terms so far," one source said, while a second source said the talks had become more active lately.

A third said that London-listed Globaltrans, which has a strategy to grow both via acquisitions and organically, is likely to acquire NefteTransService, which is controlled by brothers Vyacheslav and Vadim Aminov and company management.

NefteTransService and N-Trans group, through which founders Andrei Filatov, Konstantin Nikolayev and Nikita Mishin own stakes in Globaltrans, declined immediate comment. Globaltrans, which has a stock market free float of 54 percent, also declined to comment.

A decade ago, Russian cargo owners relied on state-owned monopoly Russian Railways as the main fleet operator, but now 70-90 percent of the country's freight fleet is privately owned.

According to state-owned Russian Railways, Russia's freight railcar fleet totals 1.1 million units. Last year cargo traffic totaled 1.3 billion tons.

Privately owned NefteTransService does not disclose its financial results but a source at the company said that its revenues stood at around $1.3 billion.

That is slightly below the $1.4 billion top line at London-listed Globaltrans, which has a market capitalization of around $2.4 billion. (Reuters)
