I never implied they were "training videos". I was referring to the video screens found on ramp level at most every station, even PHL showing estimated time of arrival by call sign as well as aircraft number and depicting gate, bag smasher infor and departure information as well, for twenty-seven years, in PHL.The article was not referring to training "videos", it was referring to the recently installed RIDS screens that are located at every B and C con gate in PHL.
