Burlington-Northern Santa Fe (BNSF) recently announced it completed a $400 million dollar track upgrade in North Dakota. Sidings, double-tracks, and track improvements between Minot and Williston, and between Devils Lake and Grand Forks. Sidings are designed to allow more trains to pass easier and track upgrades east of Devils Lake may allow increased train speeds along the traditionally slow-ordered line. Line near Devils Lake, ND was always very rough: the roughest stretch of line the Empire Builder traveled. Will be interesting to see if Empire Builder arrival times improve.
