49 49  It connects to the TCP based TIDY or TIDS server and continuously gets the Ethernet packets with the IDs. These packets are time stamped with microsecond resolution and stored. This runs all the time. Because we have a lot of data we can correlate the local time on that machine (that generated the local time stamps) and the IDs. If the Ethernet connection lags sometimes, chokes, hick ups and messes around with our packets, even drops some... Who cares. By closely monitoring all data we can define a function to calculate the Train ID from the local time on that machine.
