A public hearing before the Wasco County Planning Commission on Union Pacific’s request to expand the existing railroad siding on either side of Mosier for four miles of new second mainline track and realign the existing track has been pushed back to September. County Planning Director Angie Brewer says Union Pacific requested the postponement. The hearing had been set for July 5, and is now planned for September 6. It had already been moved from its originally scheduled date of June 7.
