Based upon Docjade's incredible AutoRail blueprint, Radar Additions is a personal flavored, automatic generic train load/drop-off manager based on signal emissions to enable required pickup stations.
This iteration adds a few replacement modules to the AutoRail blueprint that can be used for stations to request by demand transmitting request signals over radars.
Let me know if there is anything to fix - this is my first iteration on doing something that has usage patterns and standards.
Please refer to Docjade's https://www.youtube.com/watch?v=ZoEOg0GisiI&feature=youtu.be to get the AutoRail to utilize this addon properly with all the features.
