The closure this month of Trinity's Tank Car Inc.'s freight railcar manufacturing plant in Oklahoma City affected about 250 hourly and administrative employees. Tulsa-based Trinity Structural Towers Inc., which produced towers for wind farms, closed Jan. 16. About 130 hourly and administrative workers lost their jobs. Employees at both facilities were given a 60-day notice, the company said.

More than 100 Tulsans were blindsided by the news they'll lose their jobs at the start of the new year in an industry thought to be one of a few bright spots in our economy in crisis. Wind energy is a relatively new industry to this part of the country. ...The managers of the Tulsa plant would not comment on camera. But, the corporation released a written statement: "The plant closure is due to wind farm developers' difficulty in receiving financing. And due to that lack of financing developers are forced to delay upcoming projects."
