Welcome to the Train Control Systems documentation wiki! We are creating an online TCS knowledge base, hosted on a wiki (similar in format to an online encyclopedia, i.e. Wikipedia).

We have been and will continuously be expanding on topics herein until we have complied a comprehensive knowledge base that is accessible to everyone and always up-to-date.

This wiki was first launched 3/4/2020. Documenting the TCS UWT-100 Universal WiFi Throttle as our first project of many. Please check back for more information, and send us suggestions for articles that you would find helpful.

Thanks! - The TCS Team
