The women begin riding lessons and some of them get information on the railway and its security system. Dolly uses Shirley's brother, D.S. Mike Withey, to get information on the security and running of the mail train. Gloria and Connie dig out the cesspit, as they are waiting for the lime to arrive. Dolly gets information off Mike that the mail train will change its route in three weeks, meaning that the robbery will have to take place within that time. Dolly outlines the plan to them and tells them that the money on the mail train will be between £30,000,000 and £40,000,000. Each of them is nervous, but they all decide to stay in.
