Updated Report: Washout at Melrose, Iowa
On Thursday, June 25th, 2015 at 5:15 a.m. Central Time, we received a preliminary report of a washout on the main tracks at Melrose, Iowa. Melrose, Iowa is approximately 30 miles West of Ottumwa, Iowa. The estimated time for opening for the first main track is Saturday, June 27th, 2015 at 12:01 p.m. Central Time. The estimated time for opening for the second main track is Saturday, June 27th, 2015 at 6:00 p.m. Central Time.
BNSF will continue to provide you with additional information as it becomes available. Customers may experience delays of 24 to 36 hours on shipments moving through this corridor.
So they have missed their original estimate. From Amtrak map it looks like last nights #5 (26) is still stuck in Iowa (Ottumwa right now) and #6 (25) is almost 8 hours late coming into Lincoln.
