I have taken the Builder 4 times now over the past two months. Once, the train arrived at our destinations close to on time and 3 times the train was 2 or more hours late. The BNSF track work really appears to be taking its toll on any decent time keeping, especially as the train heads thru MT and ND. #8 currently on the Hi-Line is now over 9 hours late, so it will miss all connections in CHI, again. #7 heading West thru this same area is only doing modestly better. Hopefully the BNSF track work will wrap up by early fall as scheduled, but the damage has been done, as most travelers this summer appear to be experiencing significant delays on their journeys. I know the track work is very important, but it just seems to me that this summer's efforts have really impacted the Amtrak trains on this route more so than in previous summers. Somewhat ironic, since the weather has been fairly benign along the entire route so far and has not been a factor.
