The total length of the first phase of Huai'an Modern Tram is about 20.3 kilometers. All lines are ground lines, with a total of 23 stations, with an average station spacing of 923 meters and a total investment of 3.5 billion yuan. The whole track bed uses fiberglass reinforcement (GFRP) instead of steel bars in some track circuit sections. According to the track circuit installation requirements provided by Signal Specialty, the design requires that the entire track bed uses glass fiber reinforcement (GFRP) instead of steel bars in some track circuit sections. The specific requirements are as follows: 1. Use easily-cut, equal-strength glass fibers in the track circuit section. GFRP instead of steel bars, the ultimate tensile strength of glass fiber bars is 480Mpa, the elongation at break is 5%, and the overlap length of fiberglass bars and steel bars is 0.7m. 2. The corresponding arrangement of the glass fiber reinforcement (GFRP) is the same as that of the steel bar; the glass fiber reinforcement frame in the insulation section is replaced with the same specification glass fiber.
