A railroad tank car manufacturer is closing its facility in northwest Indiana and shifting production to plants in Texas and Louisiana.
The move by Union Tank Car puts nearly 450 people out of work.
The Chicago-based company cited a declining market for railroad tank cars and the cost of operating the older facility in East Chicago.
Friday was the final day of work for the 70 salaried employees and 375 hourly employees.
Company spokesman Bruce Winslow says most of the workers received their checks and benefits explanations on Thursday.
The plant was building about 60 tank cars per week as recently as September, but the company laid off about 100 workers early this year as production dropped to 30 tank cars a week.
