MFWSA Detouring on the Waco Sub

In a rare move, I caught the UP MFWSA (Ft Worth - San Antonio) train departing Taylor last week on the Waco sub.  There has been significant trackwork on the Austin Sub so the train departed to the South and took the Waco sub on its detour to San Antonio.  Not sure if it rerouted through Flatonia, or reversed the locomotives again at Smithville (not sure if the locos ran around the train at Taylor, or if they reversed it back into the yard like Amtrak the previous week) but I caught it at Coupland and crossing the Austin Western railroad in Elgin.  Video 1 is the train just south of Coupland along HWY 95 and video 2 is in Elgin.
