This document provides instructions for building a model train track using PVC pipes and connectors. It lists the materials needed, which include different lengths of PVC pipes and elbow and T-shaped connectors. It then gives directions to cut the pipes to size, connect a 15-inch pipe to elbow connectors on both ends, add 8-inch pipes to those, and finish by attaching T-connectors and the remaining 8-inch pipes to complete the track.
