The book "Water Supply of the El Paso and Southwestern Railroad from Carrizozo to Santa Rosa, N. Mex. American Society of Engineers: Transactions, No. 1170" is the result of research and engineering work done by J.L. Campbell. In this book, the author examines the problems and solutions to issues related to the water supply of hydraulic structures on the specified section of the railway. This work helps to understand the importance of efficient water supply for locomotives and passengers. Careful research into the water supply runs from Carrizozo to Santa Rosa is reflected in this book, making it a valuable source of information for specialists and interested readers interested in the engineering aspects of water supply in the life and development of railroads.
