March 20 (Reuters) - General Electric Co's transportation unit said on Tuesday several North American railroads have placed orders this year for 225 refurbished locomotives, although it declined to say which railroads ordered the equipment.
GE also said in a statement that it will deliver 80 modernized locomotives previously ordered by Canadian Pacific railway Co and 100 to Norfolk Southern Corp in 2018.
The orders were the latest evidence of major railroads seeking to control costs by refurbishing aging machinery instead of purchasing new engines.
GE will make varying upgrades to aging locomotives - some more than 20 years old - such as improvements to control systems or electrical circuitry. The changes boost hauling capacity but are cheaper than buying new, it said.
"Modernizations will most likely be a strong portion of our locomotive capital spending for a number of years," Doug Corbin, an assistant vice president at Norfolk Southern, said in a statement accompanying GE's announcement. (Reporting by Eric M. Johnson; Editing by Dan Grebler)
