Texas gets the bulk of the north flow along it's 1200+ miles of border. There has to
be a large operation in moving them across the Rio Grande even though it's not a deep

Images of the Rio Grande:
I heard that it takes 45 days on that train to travel the 1000 miles to the Texas border.
So how does that logistically work if the train is bringing say 1000/day???
