FEC has what is called by some a "prime" railroad right-of-way. The heavy weight of the rock trains required very good trackage and bridges. The railroad has mostly 136 pound-per-yard (66 kg/m) continuous-welded rail attached to concrete ties, which sits on a high quality granite roadbed. The entire railroad is controlled by centralized traffic control with constant radio communication. Because the railroad has only minor grades, it takes very little horsepower to pull very long trains at speed. trains are a normal FEC operating standard.
