50674 CCTV coverage ‘inadequate’ for 106 road at Neasden depot
July 2012 in London Underground
Method of working
A reporter believes CCTV coverage for 106 road at Neasden
depot is inadequate because the new S stock trains are only
partially visible to staff monitoring them. This has been an issue
for around a year.
Trains on 106 road have their wheel sets turned
and are driverless, but are monitored remotely on CCTV by staff in
the office. Cameras, track layout, signalling and points all need
upgrading to accommodate the S stock trains which are eight
carriages long. In practice, this means staff cannot monitor the
full length of trains.
The reporter is concerned that someone could
walk in front of a train without being seen at all. Full CCTV
coverage would mean the emergency stop button could be pressed if
someone strayed into the path of an oncoming train.
This particular issue is part of a wider problem
associated with the general upgrade work required at the depot. The
CCTV system and working practices at the depot were designed for
use with trains four carriages long and have not been fully revised
to accommodate the new rolling stock.
The reporter asks London
- If method statements for shunting eight car S stock trains can
be briefed out to all staff?
- When will civil works to upgrade 106 road take place and full
CCTV coverage be provided?
- What procedures for safe working will be implemented until 106
road is upgraded?
- If a wider review of depot procedures could be undertaken?
Response from London
London Underground would like to thank the
reporter for raising their concerns.
In answer to the reporter's concerns:
- No method statement for shunting eight car S stock trains is
required to be briefed out as only Depot Staff carry out S stock
shunting duties. All Depot Staff have been fully trained and
assessed as competent by our training department.
- September 2013 is the date the Neasden depot upgrade project
team have given for completion of the upgrade works to 106
- Whilst the facility is in its current state, wheel turning on
an eight car S stock should only be done in a controlled manner in
liaison with the Bombardier Transport UK Depot Manager. Although
this is labour intensive, it remains the best way to control the
process until all the works are completed.
- S stock shunting to the underfloor wheel lathe building is no
different from the normal S stock shunting process used in the
depot, which all S stock Shunters are trained to do. Depot
procedures are reviewed in line with LUL standards.
