It appears that the Hi-Line timekeeping has "settled down" to the expected 2-3 hour delays (especially Eastbound) that were expected for the Empire Builders when BNSF announced another summer of extensive track rehab efforts. My local BNSF folks have reiterated that timekeeping has been effected by not just the "one off" incidents that have occurred (weather, derailments, equipment issues, etc), but an increase in the amount of overall freight traffic as well, which have modestly exceeded the BNSF forecasted traffic (a busy summer for both agricultural and commercial interests). So even without all of the track work my BNSF guys say that the EBs would likely have experienced greater than normal delays this summer anyway.
Well, let's hope the fires in the west don't throw a further monkey wrench into the mix. This year's fire season would appear to last well into the Fall, given the very dry conditions throughout the entire western part of the country.
