I hate waiting for cars on the railroad track. This would be so simple to implement. Have sensors in a train and near the tracks that send data to a digital readout above the tracks with the number of trains counting down to zero. If nothing else, you could get a sense of time to wait in a direct and simple manner.-- TommyTokyo, Sep 02 2003 Just tell the time it will take. You can also use it for a warning when a train is approaching "10 seconds till impact, better get off the tracks", "9 seconds ...", ...-- kbecker, Sep 02 2003 I like it. I'd like to see both the car and second countdowns.
