Vintage Trolley Car Diagram - Engineering Blueprint & Historical Design #296098 (License: Personal Use)

This black-and-white engineering illustration depicts a side-view cross-section of an early electric streetcar, complete with annotated parts such as the pantograph (P), axle assemblies (m, m′), and support structures (A, B, C). The design emphasizes the integration of electrical power collection via overhead wires and robust undercarriage mechanics typical of late-1800s urban transit systems. Labels like “L”, “I”, and “h” indicate longitudinal members, insulators, and height dimensions critical for manufacturing and maintenance.

Used in transportation history articles, museum exhibits, engineering education resources, or patent archives; targets users researching vintage public transit technology, urban infrastructure evolution, or mechanical schematics for restoration projects.
