Positive Train Control database

[MichaelScott2]

I am wondering if there is a database schema for Positive Train Control systems? 

Here is the tidbit of information that I was given...

"Develop the track database for the I-ETMS (Electronic Train Management System) PTC System in accordance with criteria set forth in the PTC Data Model Definition document. This standard is to be published by the AAR (American Association of Railroads) as S-9501."

I'm curious if there are any databases that might give me an idea of what should be included in something like this.

Thank you.

There is not a "point and click" schema example available online. Only technical documents describing what one should look like. The closest youll get is ESRI's proposed Rail Schema, posted recently in this community & available via GitHub.
