Tube pays the price for 'cheap and cheerful' fix

News

FURTHER 'CHEAP and cheerful' London Underground (LUL) track alterations have given rise to 9,000 misaligned rail sites on the Tube's Northern Line, infrastructure contractor Tube Lines revealed this week.

Steep line gradients set by LUL mean trains will continue to run at up to half their normal speed until the defects are rectified.

The news comes a week after NCE revealed that poor quality rubber pads installed by LUL beneath rail baseplates were causing track movement (News last week).

Tube Lines Northern Line infrastructure manager Lee Jones said that LUL adjusted the track gradient to accommodate larger trains in a 'cheap and cheerful manner'.

'They [LUL] lowered the track over short lengths when you really need to run it in and out over longer distances. It's not comfortable on the passengers and rails wear more quickly, ' said Jones.

Over 3,000 of these defects have been repaired, but 6,000 remain on the Northern Line.

To remedy the problem the rail height must be adjusted by up to 30mm in some locations, calling for full tunnel base replacement.
