As soon as the train departed the station, Agar began work. Only one of the locks was secured—an SER employee later reported that typically only one lock was used—and Agar soon had the bullion boxes out of the safe. Instead of opening the box through the front, he used pincers to pull the rivets out of the iron bands that bound the box, and used wedges in the reverse of the box to open the lid without too much visible damage. He removed gold bars from inside the box from Abell & Co, weighed them with the scales he was carrying in the bag, and put the same weight of lead shot back into the box. He nailed the bars back around the box, then resealed a wax seal on the front, using a he had made himself, rather than one of the official seals of the bullion dealers. He deduced—correctly—that on the poorly lit station at Folkestone, a cursory glance at the seals would not show any change. He managed to do this before the train arrived at Redhill, which was a 35-minute journey from London Bridge. When it arrived at Redhill, Agar again hid, while the bag containing some of the gold was handed to Tester, who returned to the SER offices London, as arranged, so he could be seen by colleagues and give himself an alibi for later. Pierce took the opportunity to leave his carriage and join his confederates in the guard's van.
