Railway Track & Structures is a monthly technical magazine with more than 9,000 qualified subscribers. It is designed to meet the information needs of the track and other civil engineering-related areas of North American rail freight and passenger operators. Emphasis is placed on the $US 9 billion business of building and maintaining railway infrastructure, including track, bridges and other structures, and wayside communications and signaling systems. It is the only railway magazine devoted entirely to rail engineering and maintenance-of-way.
