Rail group Transcontainer warned of an uncertain second half of 2012 on Thursday as it reported a quadrupling of full-year profit to 3.8 billion rubles ($129.29 million).
Transcontainer's revenue for 2011 increased 35.2 percent year on year to 30.8 billion rubles. Its profit reached 3.8 billion rubles from 928 million rubles last year.
"Although the company's performance in the first quarter of 2012 remained strong, the market prospects for the second half of 2012 are still hard to predict," the company said in a statement. The company, majority owned by state monopoly Russian Railways, transports goods for a wide range of industries, including autos, consumer goods, metals and paper across Russia's vast rail network.
