This document is a project report submitted by a group of students for their Design Engineering course. It details the development of an Automatic Railway Crossing System (ARC) over multiple semesters. In the 6th semester, the students developed a PLC circuit board and program to control the ARC. They tested the circuit and program on a DELTA DVP-14SS2 PLC. The report provides snapshots of the PLC program and discusses modeling software, engineering economics, prototyping, materials selection, and future improvements including using renewable energy sources.
