In association with the work, some improvements were made to the station environment at the Waterloo station, and a minute frequency was implemented in the peaks; this involved some minor signalling changes, reversion to alternating platform use at Bank, and the use of turnover drivers and guards (where the arriving driver and guard are replaced by staff waiting at the appropriate place for the change of direction, sometimes referred to as "stepping up"). A Rear Cab Clear plunger is provided at Bank so that the arriving driver can confirm that he is clear of the cab and the "step-back" driver can depart when the signal clears. Overall, the work had cost £910,500.
