This depot is run by Metronet. In response to your enquiries, London Underground have provided the following information: Wheel/Rail Screech: Since noise measurements were completed in June 2004, new track lubricators have been installed and hand lubrication is undertaken three times a week. Additionally drivers are instructed to reduce speed in this area to further reduce noise disturbance. These measures have significantly reduced overall noise levels but monitoring continues. Train Whistles: Use of whistles is a primary means of ensuring staff safety whilst train movements are undertaken. Additionally whistles are necessarily tested prior to entry of trains into service. Following earlier claims of 'unnecessary whistle use', a memo was sent to train operators asking them to use the whistle only when necessary, whilst still abiding by the railway's safety rules. Contractor Shouting: Staff are briefed before each shift to carry out their work quietly. Any feedback from line-side neighbours which indicates that contractors or maintenance staff were unnecessarily noisy, is followed up and investigated internally. Metronet has also put a number of signs around the depot asking staff to consider our neighbours and move about quietly. Following liaison with the Metronet Depot Manager, he has assured us he will continue reminding his staff of the need to keep noise levels as low as possible during night shift work and be aware that there are a number of areas that are particularly sensitive. The location of the Permanent Way (track) Store at Hainault Depot meant the noise associated with using the store disturbed residents at neighbouring Trotwood Estate. London Underground has worked closely with Epping Forest District Council and has recently funded a relocation of the stores to a site further away from line-side neighbours. This work has recently been completed, and the council have since had no reports of excess noise. This has been a positive step towards minimising potential disturbance from the busy depot.
