Bakken oil boom driving boom in rail car manufacturing

Greenbrier has been struggling with moderating demand this year from oil companies.

The Lake Oswego, Oregon-based company grew rapidly in 2011 as strong demand for railcars to transport crude oil and sand for hydraulic fracturing enabled it to ramp up production and raise prices.

The company said last month it received orders for 2,900 railcars during the fourth quarter ended August, nearly half of what it got a year earlier.
