Railtrack and First Engineering have been blamed for management
failures in an investigation by the Health and Safety Executive
into a freight train derailment in Scotland last year.
Although the HSE investigation found that the primary cause of the
accident was track defects, it criticised Railtrack and maintenance
contractor First Engineering for not analysing information they had
on the condition of the track, and so did not spot and act on the
worsening state of the track.
The gauge of the track had been gradually getting wider and
eventually reached the point where it caused the derailment of 16
of 27 wagons on a coal train at Burntisland, on the Firth of Forth,
Fife, Scotland, on 8 July 1998. The incident caused serious
disruption to the East Coast Main Line and the track was not
re-opened until four days later.
The HSE found that faulty installation work in the 1960's was to
blame for the gauge between the rails widening. This defect was
hidden by the fastenings that secure the rail to the concrete
sleeper. HSE inspectors considered it unlikely that the faulty
installation could have been anticipated or observed in the normal
form of inspection but felt that the widening gap between the rails
should have been identified.
These management failings are similar to those found in HSE's
investigation of the accident at Bexley, Kent, on 4 February 1997,
when a ballast train derailed due to poor track condition.
Two Balfour Beatty rail maintenance companies together with
Railtrack were fined a total of £150,000 in September 1998 and
the HSE issued a damning report into the crash last March.
Several of the lessons learned from the Bexley report have been
reiterated in the Burntisland investigation. Maintenance
contractors should ensure that competent people are employed, and
should undertake ongoing monitoring to make sure that adequate
systems and resources are used, the report found. Railtrack was
told to monitor its maintenance contractors' performance, and
should review the effectiveness of the systems so that the
infrastructure is maintained safely.
Two other stretches of track with the same fasteners have been
identified. Railtrack has agreed to replace these sections by April
2000 and speed restrictions will apply until these works are
completed.
The HSE investigation found that there was not sufficient evidence
to prosecute either firm. Railtrack has drawn up an action plan to
address the issues raised by the investigation and HSE said it will
review this plan at the end of October.
