Not "automated", but a long story.
At Glasgow Central in the 80s, there was an announcer who some of us christened "Paddy" as he seemed to have a very thick Irish accent - he was actually of Lithuanian descent and had ended up as the announcer due to having been made redundant from another post, but I digress. One evening he announced that "The 17:18 to East Kilbride is the Front Train at Platform 5", followed shortly thereafter by "The 17:14 Train to Barrhead is the Rear Train at Platform 5". For those of you unfamiliar with Central, it's a terminus. You can see why this was problematic. Cue mumblings from passengers along the lines of "If it's got anything to do with him, I'm not bloody surprised".
Fast forward a few months, and there were numerous complaints about the quality of the public address system at Central, to the extent that orders came from the very top to find out what the issue was and repair it. The Telecomms folks made strenuous efforts to replicate the problem to no avail. Finally, someone hit on the idea of contacting the complainants in an effort to identify if these issues happened at specific times of day. No pattern was identified, until someone had the equally bright idea of cross-referencing the complaints to "Paddy"'s shift pattern. You can guess what they found.....
