07/03/2024 Chadron, NE. Not much left of the original CNW Cowboy Line. Chadron has a good sized yard still in use with the Nebraska Northwestern railroad interchanging with the BNSF in Crawford, NE. HWY 20 follows the old Cowboy line for a long ways. Many of the bridges have been converted for pedestrians. Valentine, NE. This Old CNW bridge is quite popular and makes for a very scenic walk or bike ride. Be better with trains though!
