Porter, Indiana, historically known as Porter Junction, served as a crucial railway intersection for major east-west trunk lines in the late 19th and early 20th centuries. This strategic location was where the Michigan Central Railroad (M.C.) and the Lake Shore & Michigan Southern Railway (part of the New York Central System), along with other prominent lines like the Pennsylvania Railroad, converged and crossed. The interlocking tower shown was indispensable for managing the complex movements of trains, enabling safe and efficient traffic flow through this bustling hub.
