U-rail was used on a number of CS railroads. Some has been found where the RR bridge over the Tennessee River is located from the line that ran to Nashville from there. For the 1864 campaign in the west the Union rebuilt every CS railroad in Tennessee to t-rail so that it could withstand the heavy amount of trains that Sherman mandated for his campaign (some 150 cars per day into Chattanooga).

The museum at Tunnel Hill, GA where the old RR tunnel (and current RR tunnel) runs through Cheektogeta Ridge has examples of strap, u-rail and old t-rail (much smaller than modern t-rail). Strap rail, including on the line that ran from Opelika, Alabama to Montgomery that was torn up in 1864 by Lovell Rousseau's raiders, was the worst and lasted least.
