[Mark Gleeson]

Full radio coverage is provided from Cobh to Heuston, question is the time from Port Laois getting the call to the station master in Port Laois approving it and ringing Connolly and talking to the regulator who in turn might have to seek approval then call the driver, there was a 10 minute window to do it it should have been possible. The train radio is a required item it must be working, even if the driver had not set up the train id correctly (quite possible given the fact the train was not really timetabled) there is a broadcast mode where everyone hears

In the old days the Port Loais signalman would ring Portarlington who would then force the train to stop
