The Rail Accident Investigation Branch (RAIB) has released its report
into the unauthorised train movement and subsequent derailment at
Haymarket, Edinburgh, on Saturday 14 January 2006.
The full report is available here:
A summary of the key points from the report are:
On Saturday 14 January 2006 a train loaded with ballast left a section
of line that was under engineers' possession without authority, and
ran onto a line open to other traffic. It was diverted onto a line
on which a passenger train was approaching from the opposite direction.
The ballast train stopped in Haymarket station when the driver realised
he was travelling on the wrong line, and the passenger train was stopped
by the signaller.
The immediate cause of the incident was that the driver of the ballast
train left the engineering possession without obtaining authority
from the signaller. There were eight causal factors, and two contributory
factors to the incident.
Subsequently, during tests on the brakes of the ballast train, one
wagon became derailed. There were no injuries, and minor damage to
a set of points. The immediate cause of the derailment was a fitter
carrying out a brake test while the train was standing over points
that had been damaged in the first incident. There was one causal
factor.
Recommendations
The RAIB has made three recommendations as a result of its investigation.
These cover:
• revisions to the rules governing the management of engineering
possessions;
• the competence of staff;
• the planning of engineering work on the railway.
The Rail Accident Investigation Branch (RAIB) has released its report
into the blowback of a locomotive 'fire' at Grosmont on the North
Yorkshire Moors Railway on 16 April 2006.
The full report is available here:
A summary of the key points from the report are;
On Sunday 16 April 2006 a locomotive hauling a passenger service on
the North Yorkshire Moors Railway suffered a blowback of its fire
south of Grosmont station. The blowback filled part of the footplate
with flame for between 4 and 10 seconds. The locomotive driver suffered
minor burns.
The immediate cause of the accident was a loss of forward draft at
a time that the firehole doors were open. The loss of draft was caused
by the failure of a blastpipe base/saddle plate weld that was made
undersized when the locomotive was originally built, allowing the
blast pipe to move out of line. There were two causal factors, eight
contributory factors and two underlying causes identified.
Recommendations
The RAIB has made nine recommendations as a result of its investigation.
These cover:
• the size, inspection and repair of blast pipe base/saddle plate
welds;
• provision for mechanical inspections when outsourcing work;
• assessment of hazards to train crew and public in the development
of maintenance schedules;
• provision of first aid kits on minor railway locomotive footplates;
• annealing of copper blower feed pipes; and
• notification of incidents between the heritage sector and the
mainline railway.
Rail Accident Investigation Branch (RAIB) has released its report into
the derailment of a freight train near Waterside, East Ayrshire, on
21 January 2006.
The full report is available here:
A summary of the key points from the reportare;
On Saturday 21 January 2006 the rear six wagons of a freight train travelling
from Chalmerston to Carlisle derailed near Waterside. There were no
injuries, but over two miles of the freight-only track was damaged in
the incident.
The immediate cause of the incident was a fracture on the running rail
within a section of track owned by Scottish Coal, which allowed the
leading wheelset of one wagon to derail. The following five wagons remained
on the track but derailed as the train came to a stand. There were four
causal factors and six contributory factors to the incident.
Recommendations
The RAIB has made seven recommendations as a result of its investigation,
covering the arrangements for the management of the track. |
