2. Provide any strategy, decision or operational discussion on a) deliberately reducing lift service at Wapping and/or Shadwell and b) the length of time taken to bring the lifts back in service.

Reduced lift availability during normal service hours at Wapping and Shadwell stations is governed solely by the correct functioning of the associated mechanical and electrical equipment. However, where equipment has failed or is found to be faulty during inspection then the lift in question will only be returned to service where a safe repair is possible. If during inspection by the relevant specialists any potential safety issues or likelihood of further failure are identified then the lift will be kept out of service in line with good engineering practice. Return to service will primarily be dependent on the availability of replacement parts.    

Consequently, the lifts were taken out of service either due to mechanical failure or due to a safety risk that required major intervention. In all cases the structural integrity of the lifts was paramount.

3. Provide any correspondence or memoranda provided to station staff at Wapping/Shadwell on the maintenance of the lifts and estimated time to bring back into service.

The London Overground Infrastructure Manager briefs the London Overground Operations Concession holder regarding the operational status of the lifts. The Concession holder then provides briefing information to its operational staff as necessary and such information is not held by TfL. In addition, the TfL publicity department is informed of the time when the lifts will be returned to service. 

4. The relevant service level agreement/targets/KPIs on bringing lifts back into service and act correspondence escalating the need to repair the lifts.

Where the lifts were taken out of service due to reasons other than mechanical failure, for example due to the likelihood of mechanical failure, this was done with the agreement of the Infrastructure Maintenance Contractor and the Operations Concession holder.     

If this is not the information you are looking for, please feel free to contact me.
