Software problem to blame for Central Line shutdown, Metronet admits

The Metronet Rail consortium has admitted that software problems lay behind a shutdown of Central Line services on the London Underground last week.

The Metronet Rail consortium has admitted that software problems lay behind a shutdown of Central Line services on the London Underground last week.

Metronet Rail, the consortium responsible for renewing two-thirds of the Tube’s infrastructure under a public-private partnership (PPP) scheme, apologised for the Central Line delays last Monday (20 November 2006).

The consortium said the loading of new signalling software containing London Underground’s revised timetabling information had “caused a total break-down of the systems at the start of service”.

Central Line trains began running at 8.45am on Monday, but Transport for London said minor delays had occurred on subsequent days while the problems were resolved.

The Metronet apology came just days after the consortium was slammed in the PPP Arbiter’s annual report on its performance. The arbiter said Metronet had not performed in line with good industry practice over the first three years of the London Underground PPP.
