Grade Crossing US ATWS 'Advanced Train Warning System'. You will have to use Boats ATLS system to set this up. Set it on the same channel as the crossing it is protecting. Or you could set it up on a seperate channel and have the triggers set out further than the crossing triggers for a truly advance warning. Thanks to SantaFeBuff for pointing this sign out.
A special thanks to the following Trainz members for contributing to the working script's of these crossings, MartinVK , Phil Cambell at http://www.worldoftrainz.com, Andi06 at 'www.ajsmith.nildram.co.uk'. Without there help, these crossings would not be animated. Also thank's to the many Trainz members who input praise, help and constructive critisism on the forum which enabled me to refine the crossings to what they are now.
Please read the instructions located in the main folder for details on added features.
