ACCIDENT INVESTIGATION UNIT
The RAIU,
a functionally independent investigation unit of the Railway Safety Commission
(RSC), has issued reports into the collision between Track Recording Vehicle
(TRV) No. 700 (EM50) and the one of the gates at Buttevant Level Crossing
(XC219) and into a person struck at level crossing XE039 Limerick-Ennis.
Summaries are noted here.
Buttevant
At 10:22 on Friday 2 July 2010, the 08:00 Dublin-Cork passed through
the Buttevant Level Crossing without incident. Approximately thirty seconds
later the TRV approached the crossing in the opposite direction as the Gate
Keeper was in the process of closing the gates across the railway line. The TRV
struck one of the gates damaging it and the vehicle. There were no injuries or
fatalities.
The Gate
Keeper was passed as competent to operate Buttevant Level Crossing on 22 June
2010. He was positioned in a raised cabin at the crossing. He had previously
worked at Myrtlehill level crossing (Cork-Cobh) from 8 September 2008.
A TRV
Driver and Operator were on board the TRV at the time of the accident. Both were
employed by Lloyd Rail. Both the TRV Driver and Operator were deemed competent,
and had followed the procedures in the IÉ Rule Book for the operation of TRVs.
At 09:38,
the TRV departed Cork for Inchicore Works under a Special Running Notice. At
10:14:08 the TRV struck the Strike-In-Point for Buttevant Level Crossing on the
Up Line. This initiated the procedures for the Gate Keeper to close the gates of
the crossing to road traffic, therefore opening the gates to rail traffic.
At
10:20:41, the 08:00 Dublin-Cork struck the Strike-In-Point for the Level
Crossing on the Down Line. At 10:22:47 the passenger train passed through the
crossing and cleared it at 10:22:59. It was the first to arrive at the crossing
as it was travelling at a faster speed than the TRV. After the train passed
through the crossing, the Gate Keeper then began opening the gates to road
traffic, therefore closing them across the railway line.
At
10:23:26, the TRV arrived at the crossing, striking the Down line gate. The TRV
Driver applied the emergency brake, but the TRV continued through the crossing,
coming to a stop 214m beyond it.
The TRV
was not in recording mode at the time of the accident. The TRV is 12.8m long and
weighs 23 tonnes. It has a forward facing camera, however, this only operates
when the TRV is recording, and therefore was not recording at the time of the
accident. The TRV does not have an event recorder fitted. The maximum
permissible speed for a TRV is 64 km/h and it was travelling at this speed at
the time of the accident. The TRV is not equipped with CAWS receiving equipment.
The RAIU said that “the condition or operation of the TRV was not contributory
to the accident.”
The train
consisted of locomotive 234 + 8 Mk IV carriages, with locomotive leading. The
train was travelling at approximately 144 km/h, which was the line limit. The
RAIU said “The condition or operation of the train was not contributory to the
accident.”
IÉ staff,
under the supervision of the RAIU, tested the crossing equipment post accident,
including the Indication Alarm and associated audible alarm, Gate Lock Lever and
Gate Lever Lock. No faults were found with any of the equipment, and no faults
have been recorded at the crossing since the accident.
The Gate
Keeper was subjected to the screening for drugs post accident, as per Iɑs
Drugs and Alcohol Policy, for which he tested positive for Cannabis on 2 July
2010. Iɑs Chief Medical Officer stated in his report that the presence of
this substance in his system “has significant implications for his ability to
perform his duties in a safe and satisfactory manner”.
The RAIU
concluded “The Gate Keeper did not fully adhere to the 'Instructions to the
Crossing Keeper for the Operation of Buttevant (XC219)' as he did not check the
Indication Alarm, after the passing of the Train, to ensure that a second train
was not approaching. The Gate Keeper may have assumed that the Train was the
only train approaching the Level Crossing and therefore may not have checked the
Indication Alarm which was displaying the yellow 'Warning' Lamp. This omission
may have been, at least partly, as a result of the presence of Cannabis in his
system, which is known to affect concentration and co-ordination.”
“Approach
locking or route locking was not provided at the Level Crossing, which would
have acted as an engineered safeguard, to ensure that the Level Crossing gates
could not be closed across the railway line while the yellow 'Warning' Lamp is
illuminating on the Indication Alarm. The absence of this engineered safeguard
therefore allowed the Gate Keeper to close the Level Crossing gates across the
railway while the TRV was approaching. These risks were not identified by any
risk assessment as Iɑs Principles of Interlocking standard was issued
fourteen years after the installation of the Level Crossing.”
“IÉ‘s
Drugs and Alcohol Policy was not fully adopted in that the 5% random sampling
for drugs of safety critical staff, required of the Policy, was not fully
adopted. However, given that there only a 5% chance of the Gate Keeper been
randomly selected, is it unlikely that the Gate Keeper would have been tested
prior to the accident occurring.”
The RAIU
noted that there were 14 gate strikes by trains at CX type level crossings over
the 10 years prior to the accident, but none had a similar signalling system to
Buttevant. Approach locking or route locking were not provided at Buttevant.
“At the
time, or since, the installation of the Level Crossing 23 years ago, no
interlocking system (such as the signal level backlocking system) was introduced
to ensure that the interlocking associated with a signal or other movement
authority would only be released when it is safe to do so, as set out in Iɑs
signalling standard, I-SIG-2022 – Principles of Interlocking, Issue 1.0.”
As this
standard was introduced 14 years after the installation of the crossing
equipment at Buttevant, “its requirements in relation to approach locking or
route locking were not included at the installation stage of the Level Crossing,
nor were they subsequently introduced after the introduction of the standard.”
“However,
this Level Crossing is likely to have been exempted from approach locking as the
standard states that 'interlocking should be applied to level crossings, unless
the signalman can observe train movements and risk assessment shows that
approach locking need not be provided.' This was the case at Buttevant where the
Gate Keeper had unobstructed views of the railway. This substitution of
engineered safeguards for Gate Keeper actions therefore relies on the Gate
Keeper to carry out his/her instructions correctly with no allowance for human
error.”
“Had
approach locking or route locking been provided it would have acted as an
engineered safeguard in preventing the Level Crossing gates to be opened to the
public road, and closed to the railway as a train was approaching. The operation
of the gates would therefore only be permitted when the Level Crossing track
circuits were clear of all trains, and would not allow for the human error to
occur.”
The RAIU
said that the immediate cause of this accident was that:
XE309
At approximately 22:00 on 27 June 2010 the driver of the 21:45
Ennis-Limerick sounded the horn on the approach to user worked level crossing
XE039 at 15 miles 135 yards (near Sixmilebridge). The train consisted of
carriages 2724, 2715 and 2753. As the driver was sounding the horn he observed a
farmer, 162m ahead of the train, pushing a cow through the gates of XE039 onto
the railway, approaching the railway line from the train driver’s right. As
the train continued to approach XE039 the driver applied the brake and sounded
the horn twice. The farmer continued to push the cow but the train struck the
farmer and the cow. As the train passed over XE039 the driver heard a noise and
saw the cow fall to the left of the train, he was not aware that the train had
struck the farmer. The train stopped 200m beyond XE039. The driver went back to
XE039 on foot and found both the farmer and the cow on the side of the track on
the opposite side of the track to the one they had approached from.
The driver
rang the Limerick Check Signalman using his personal mobile telephone to advise
that the farmer had been struck and the emergency services were required. He
could not ring the controlling signalman, the Galway Line Signalman, as he did
not have the telephone number with him at the crossing. The Limerick Check
Signalman rang the Galway Line Signalman, and requested the attendance of the
emergency services. The contact information for the driver was not given to the
Emergency Services Operator.
The
location of the accident site was initially given in railway terms as the 15
milepost in accordance with section A of the Rule Book (IÉ, 2007). The Galway
Line Signalman did not have any other information to facilitate location of the
accident and advised he would ring the emergency services back. The townland the
accident occurred in was given eight minutes after initial contact was made with
the Emergency Services Operator and the name of the townland provided was
Rathaline. However, XE039 is located in the townland of Rathlaheen South. The
emergency services were not advised of the presence of an access road leading to
XE039, resulting in their accessing the railway at overbridge OBE48, 552m away
from XE039 over ballasted track, delaying the emergency response. In this
instance, as the driver was familiar with the area, he was able to guide the
ambulance service to the access road, which allowed the ambulance be driven up
to XE039.
Information
available to the Traffic Regulator in CTC was not transmitted to the emergency
services. This included the location of XE039 overlaid onto a map with
co-ordinates and the access road for XE039. Had the information available to IÉ
been used the delay could have been avoided.
“XE039
is an Occupation type LC [sic]. This means that it has manually operated gates
that are opened and closed by the LC user, which are normally kept closed across
the road.” The farmer, who was one of two users working on farmland on both
sides of the railway, was fatally injured and pronounced dead at the scene. The
accident occurred just before sunset and the weather was dry with some cloud.
The RAIU
noted “XE039 is on the flight path for Shannon airport, which crosses the
railway, and the glide slope for the airport is approximately 345m above the LC.
It was observed that the noise of airplanes at XE039 is sufficiently loud to
reduce a person’s ability to hear the engine and track noise of an approaching
train. Flights were scheduled at Shannon airport around the time of the accident
but it was not possible to determine if any airplanes were overhead as the train
approached.”
“The
performance of the train was not found to have contributed to the accident.”
“The 1s
between the sighting of the Farmer and the application of the train brakes by
the Train Driver shown by the event recorder demonstrates that there was no
delay by the Train Driver in responding to the presence of the Farmer.”
“Based on the braking performance of the train it is unlikely that had the
Train Driver made an emergency brake when the Farmer was observed that the
accident would have been prevented. The train would have stopping beyond XE039
regardless of how the brakes were applied.”
The RAIU
noted “The controls put in place by IÉ were not found to be adequately
managing the risks at XE039 as:
