 The Abbots Ripton signalman kept trying to raise Huntingdon, but without success; when the Huntingdon signalman did answer he first refused to accept any message not starting with a code to indicate time sent, and rebuffed subsequent sends with an 'MQ' code – roughly translating as "Go away, I'm busy".Indeed, he was; he was accepting the Leeds express and passing it on to the next signal box.At 6.52, after trying and failing for 8 minutes to pass his message to Huntingdon South, the Abbots Ripton signalman sent the 5-beat 'obstruction danger' bell signal to Stukeley.
