The Trainz CDP Extractor is a software tool designed to extract the contents of CDP files, allowing users to access and manage the individual assets within. This tool is particularly useful for Trainz content creators, as it enables them to inspect, modify, and package their content for distribution.

A popular open-source utility available on GitHub that allows you to list contents, search for specific KUIDs, and extract individual assets from a CDP file.

Today, many users utilize the CDP Extractor to rescue legacy content. As N3V Games moves toward subscription models and cloud-based asset management with Trainz Railroad Simulator 2022 and beyond, older file formats risk being left behind.
