APPENDIX 1
PERFORMANCE AGAINST TARGETS UP TO PERIOD
7, 2004-05:
BAKERLOO LINE
— Performance continues to improve
in most areas on the Bakerloo line, improving overall by approximately
21% compared to the same period last year.
— The major improvements in LCH performance
has been delivered chiefly through fewer track fires and the length
of consequent delays.
— Closer working with the lift contractor,
OTIS, has reduced the number of lift failures by two per period
and reduced the average duration of closures from 80 minutes to
50 minutes.
CENTRAL LINE
— MRBCV has been successful in improving
the overall Availability score for the Central Line by approx
8% compared to the same period last year.
— The number of incidents recorded
per period has reduced by 8%.
— Good performance has been recorded
on L&E (Lifts & Escalators), Stations, and Track Speed
Restrictions (TSRs). The number of station closures caused by
L&E is consistently better than target and has reduced by
approximately 18%.
VICTORIA LINE
— Overall, Victoria line performance
is at the same level experienced during 2003-04.
— Two improvement projects introduced
to address the poor performance of signals have proved an early
success. Compared to the same period last year, signal performance
is approximately 9% better.
— Other improvement projects such as
track connections and co-incidence circuit modification and relay
replacement should specifically address the main causes of failure.
Results are expected by year end.
WATERLOO AND
CITY AND
OTHER LINES
— Poor rolling stock and signalling
performance during the last three periods affected the overall
score for the Waterloo & City line during the first half of
the year.
— Various initiatives, including signalling
modifications, power facilities enhancement and centralised control
are being developed to address these problems.
— Significant progress has been made
in reducing failures which affect other lines (MRSSL & Tube
Lines). To date only 13,819 LCHs have been incurred, compared
with 50,832 LCHs during the same period last year—a 73%
reduction.
DISTRICT LINE
— The District line availability has
improved by 23% in the last seven periods compared to average
figures in 2003-04.
— Performance has been consistently
better than PPP benchmark with the year-end forecast expected
to be better than business target.
— Track and Fleet activities have been
the major contributors, largely as a result of improved inspections,
a block joint programme and better root cause analysis and mitigation.
MCH LINE
— Overall availability on the MCH lines
has improved by 35% compared to 2003-04 figures.
— This improving trend has been consistently
better than PPP benchmark and business targets and this trend
forecast to continue.
— Train reliability programmes have
delivered the majority of this improvement, particularly the C-stock
trains which service the Circle, Hammersmith & City and part
of the District lines.
EAST LONDON
LINE
— Performance on the East London line
declined by 5% and "Other lines" 14% compared to 2003-04.
— The number of signal faults has increase
on "Other Lines" with a peak of 60,000 LCHs in period
5. A number of programmes are underway to increase their availability,
for example:
— Enhanced inspection regime to pro-actively
identify and resolve issues;
— Track wire replacement programme in the
area
— between Barons Court and Hammersmith;
— Lever frame contact at Rayner's Lane;
— Strategic location of Technical Officers
to ensure fast response to faults;
OTHER LINES
— Track reliability has improved by
60% between Barons Court and Acton Town due to an intensive improvement
programme.
