The company said the loan had been led by development banks the European Bank for Reconstruction and Development (EBRD) and International Finance Corp (IFC) -- a unit of the World Bank.
Its total loan facilities with the two agencies is now around $420 million, the company said.
Brunswick is considering the launch of a $500 million Eurobond by the year end to continue its expansion plan, two sources told Reuters last month, ahead of a potential initial public share offer (IPO) in 2012.
Russian companies have raised around $4.5 billion from IPOs in the year to date, compared with $5.5 billion for the whole of 2010, but recent volatile stock-markets have caused many to reconsider their plans.
A spokesman for Brunswick Rail declined to comment on the Eurobond or IPO plans.
