The 90lb rail, also referred to as 90ARA-A rail or TR45 rail, is an AREMA-standard steel rail designed for medium to heavy-duty track systems. With a nominal weight of 90 lb/yd (44.65 kg/m), this rail profile delivers a practical balance between load capacity, durability, and cost efficiency.
Manufactured from carbon steel or AREMA-specified rail grades, the 90lb rail performs well under repeated wheel loads, impact stress, and long-term wear. It is widely used in industrial railways, mining haulage lines, port crane tracks, and light mainline or service rail applications.
GlorySteelWork provides stable quality control, flexible production lengths, and export-ready supply for global projects.
Below is the standard 90lb rail (TR45 / 90ARA-A) profile and dimensions. This overview helps you quickly check the key measurements. For custom lengths or special specifications, we can provide tailored solutions.
