A press release from the UK RAIB:
RAIB is investigating an incident that occurred at 17:25 hrs on Saturday 7 March 2015, in which train reporting number 1Z67, the 16:35 hrs service from Bristol Temple Meads to Southend, passed a signal at danger on the approach to Wootton Bassett junction, Wiltshire. The train subsequently came to a stand across the junction. The signal was being maintained at danger in order to protect the movement of a previous train. However, at the time that the SPAD occurred, this previous train had already passed through the junction and was continuing on its journey. No injuries, damage or derailment occurred as a result of the SPAD.
Wootton Bassett junction is situated between Chippenham and Swindon stations on the Great Western main line and is the point at which the line from Bristol, via Bath, converges with the line from South Wales. It is a double track high speed junction which also features low speed crossovers between the up and down main lines (see figure below for detail).

Up Badminton, Down Badminton, Up Main and Down Main (image courtesy of Network Rail)
The junction is protected from trains approaching on the up main from Chippenham by signal number SN45, which is equipped with both the Automatic Warning System (AWS) and the Train Protection and Warning System (TPWS). This signal is preceded on the up main by signal SN43, which is also equipped with AWS and TPWS. The maximum permitted line speed for trains approaching the junction from this direction is normally 125 mph. However, on 7 March, a temporary speed restriction (TSR) of 85 mph was in place on the approach to signal SN45. A temporary AWS magnet had been placed on the approach to signal SN43 to warn drivers of this TSR.

The train which passed signal SN45 at danger consisted of steam locomotive number 34067 ‘Tangmere’, and its tender, coupled to 13 coaches. The locomotive is equipped with AWS and TPWS equipment.
The RAIB’s preliminary examination has shown that, at around 17:24 hrs, train 1Z67 was approaching signal SN43 at 59 mph, when it passed over the temporary AWS magnet associated with the TSR. This created both an audible and visual warning in the locomotive’s cab. However, as the driver did not acknowledge this warning within 2.7 seconds, the AWS system on the locomotive automatically applied the train’s brakes. This brake application should have resulted in the train being brought to a stand. In these circumstances, the railway rule book requires that the driver immediately contact the signaller.
The RAIB has found evidence that the driver of 1Z67 did not bring the train to a stand and contact the signaller after experiencing this brake application. Evidence shows that the driver and fireman instead took an action which cancelled the effect of the AWS braking demand after a short period and a reduction in train speed of only around 8 mph. The action taken also had the effect of making subsequent AWS or TPWS brake demands ineffective.
Shortly after passing the AWS magnet for the TSR, the train passed signal SN43, which was at caution. Although the AWS warning associated with this signal was acknowledged by the driver, the speed of the train was not then reduced appropriately on the approach to the next signal, SN45, which was at danger. Because of the earlier actions of the driver and fireman, the TPWS equipment associated with signal SN45 was unable to control the speed of the train on approach to this signal.
As train 1Z67 approached signal SN45, the driver saw that it was at danger and fully applied the train’s brakes. However, by this point there was insufficient distance remaining to bring the train to a stand before it reached the junction beyond SN45. The train subsequently stopped, standing on both the crossovers and the up and down Badminton lines, at around 17:26 hrs. The signalling system had already set the points at the junction in anticipation of the later movement of 1Z67 across it; this meant that no damage was sustained to either the train or the infrastructure as a result of the SPAD.
The RAIB has found no evidence of any malfunction of the signalling, AWS or TPWS equipment involved in the incident.
The RAIB’s investigation will consider the factors that contributed to signal SN45 being passed at danger, including the position of the temporary AWS magnet associated with the TSR. The investigation will also examine the factors that influenced the actions of the train crew, the adequacy of the safety systems installed on the locomotive and the safety management arrangements.
RAIB’s investigation is independent of any investigation by the Office of Rail Regulation.
We will publish our findings, including any recommendations to improve safety, at the conclusion of our investigation.
These findings will be available on the our website.
There are 15 potential Pre-Summit Courses to choose from in June and five of the courses are new. That’s probably why so many people are asking which course would be best for them. Therefore, I thought I’d share my thoughts to help people make the best choice.
First, the 15 Courses are:
- 2-Day TapRooT® Incident Investigation & Root Cause Analysis Course
- Special 2-Day Equifactor® Equipment Troubleshooting and Root Cause Analysis
- Advanced Causal Factor Development Course
- Advanced Trending Techniques
- TapRooT® Analyzing and Fixing Safety Culture Issues
- Risk Assessment and Management Best Practices
- TapRooT® Quality/Six Sigma/Lean Advanced Root Cause Analysis Training
- Getting the Most from Your TapRooT® Software
- Hazard Recognition
- Proactive Use of TapRooT®
- NEW Interviewing & Investigation Basics
- NEW Combating Fatigue
- NEW Understanding and Stopping Human Error
- NEW Root Cause Analysis for Sentinel Events & Healthcare Quality Improvement
- NEW Creative Corrective Actions
Next, let me say that I like all these courses. I’ve hand-picked them to be included before the Summit because I think they will help you solve some of your biggest problems. But I understand that you can only attend one of these courses and that you want to pick the best one, so I’ll offer some advice.
If you haven’t attended a TapRooT® Root Cause Analysis Course before, then you should consider attending the 2-Day TapRooT® Incident Investigation and Root Cause Analysis Course. This is the basic/starter TapRooT® Course that all investigators/root cause analysts should take. It will make the Summit much more valuable if you understand how the TapRooT® Root Cause Analysis System works. And it will help you perform much better investigations of safety, quality, and production issues. This course (like all Pre-Summit Courses) is completely guaranteed. We know that you and your management will agree that you will find root causes that you previously would have missed and develop much more effective corrective actions.
Need to improve equipment reliability and apply advanced equipment troubleshooting techniques? Then the Special 2-Day Equifactor® Equipment Troubleshooting and Root Cause Analysis Course is for you. You will learn to apply Heinz Bloch’s advanced troubleshooting techniques to understand how equipment failures occurred. You will then learn to take that information, organize it in a SnapCharT®, identify the Causal Factors, and find each Causal Factors root causes using the TapRooT® Root Cause Tree®. Even equipment troubleshooting experts that have attended this course have commented on the helpfulness of the Heinz Bloch troubleshooting tables and the TapRooT® Root Cause Analysis System.
Want to improve your TapRoot® Skills, especially your ability to identify Causal Factors? Then the Advanced Causal Factor Development Course is for you. Ken Turnbull teaches this course using recent examples of accidents, incidents, and near-misses – some straight from the press. You will get lot’s of hands-on exercise practice and instructor feedback.
Do you need to learn to trend your safety and performance data? Especially data from infrequently occurring accident statistics? Would you like to prove that you have improved performance? Or do you need to mathematically demonstrate that a “trend” really isn’t a trend, but rather, is just normal process variation? That’s what the Advanced Trending Techniques Course is all about. I developed after I saw a client’s advanced trending best practices that blew me away. This was trending that really worked and showed when a trend was real and when it was just normal process variation. It was based on advanced lean/six sigma techniques that were specially modified for low frequency accident data. But the same techniques can be applied to all your data. It truly is a one size fits all trending program that will help your management focus their improvement initiative. In the course you will learn how to draw advanced graphs and practice your skills so that you can apply the techniques to your data back home. The course is taught by Kevin McManus, a quality/safety guru, and I know that you will find it enlightening and very useful.
The topic of Safety Culture is a hot button in the nuclear, oil, and aviation industry. If you would like to analyze and improve your safety culture, then the TapRooT® Analyzing and Fixing Safety Culture Issues Course is for you. Brian Tink and Brian Tink (Jr & Sr) will show you how to use TapRooT® Tools along with culture analysis tools to analyze and fix safety culture issues. Part of this course is a practice safety culture analysis for your company. If safety culture is a hot button topic at your company, don’t miss this course.
Interested in risk assessment and management? Want to learn about the latest international standards and how they can help keep your management out of trouble? Then you need to listen to risk management guru Jim Whiting in his course: Risk Assessment and Management Best Practices. Jim shares all the latest risk management techniques and tons of documentation that you will use when you return to work
Interested in applying advanced root cause analysis techniques in a Lean, Six Sigma, or Quality program? Then attend the TapRooT® Quality/Six Sigma/Lean Advanced Root Cause Analysis Training taught by Chris Vallee. Chris is a Six Sigma Black Belt. He will show you how to use TapRooT® Techniques to analyze and fix quality problems, lean waste issues, and problems discovered using Six Sigma techniques.
Do you provide technical support for the TapRooT® Software? Are you a TapRooT® Software “Power Users” who wants to learn the latest tricks and see the latest software updates? Are you interested in the changes coming in Version 6 of the TapRooT® Software. Are you responsible for setting up the TapRoot® Software and preparing the trending fields and linking the software to other databases? Then you want to attend the Getting the Most from Your TapRooT® Software Course taught by Dan VerLinde, VP for Software Development at SI. You will be amazed how much you learn and how much better your software usage will be.
What is a hazard? Do you see them before they can cause an accident? If you are interested in Hazard recognition and elimination, then the Hazard Recognition Course is for you. Peter Berkholtz, a TapRoot® Instructor from Australia with 25 years of mining and industrial experience, will teach this practical course. Don’t let hazards sneak up on you. Recognize and eliminate them!
Did you know you could use the TapRooT® System to solve problems before they cause a crisis? If you want to stop problems BEFORE they happen, then the Proactive Use of TapRooT® Course is for you! Dave Janney developed this course after realizing that people would rather stop fatalities before they happen rather than investigate fatalities after they happen. He explains how TapRooT® can be applied to improve auditing, observations and BBS, and pre-job hazard assessments. Learn new ways to apply the TapRoot® System to proactively improve performance at your facility.
And now for the new courses …
Interviewing and Investigation Basics: We’ve taught this course before but after we had so many positive comments about Barbara Phillips talk on Body language and interviewing at last year’s TapRooT® Summit, we decided to completely revise the course adding new material on interviewing, I think you will find this course to be engaging, useful, practical, and a good use of your time if you are interested in effective interview techniques and the tools and practices needed to collect information for an effective root cause analysis.
Combating Fatigue: fatigue in the workplace (and while driving) is one of the most frequent, and least investigated, causes of accidents. Studies of actual auto accidents that were video tapped inside the car for later analysis showed that actual fatigue and sleeping was often NEVER reported but was the cause of the accident. What can you do to fight fatigue at your company? Get great ideas from fatigue expert Bill Sirois. Learn to understand the risks of fatigue. Learn the five levels of defense against fatigue. Learn to build and improve a Fatigue Risk Management System (required in several industries). Understand specific methods to handle fatigue in high hazard industries. This course has been completely updated since it was last given before the 2012 Summit and we see it as completely new.
Understanding and Stopping Human Error: Mark Paradies, President of System Improvements and Joel Haight, Professor of Industrial Engineering at the University of Pittsburg, will bring their considerable knowledge of the practical application of human factors engineering to this newly developed course. The course will cover the human abilities and limitations that lead to human error, how to understand error likely situations and error causing designs, and how to apply error reducing techniques that work and to understand why some error reducing techniques that are frequently suggested are of little practical value. If you are interested in human performance and stopping human error (or at least reducing it as far as practical), then don’t miss this course.
Root Cause Analysis for Sentinel Events & Healthcare Quality Improvement: Ed Skompski, Vice President at System Improvements, has created a 2-Day TapRooT® Course especially for the healthcare community that focuses on the analysis of the root causes of sentinell events and healthcare quality issues. The course is built around real clinical events and uses the TapRooT® System, a recognized good practice in the healthcare industry and that the terminology is recognized by The Joint Commission.
Creative Corrective Actions: You may remember this course from the past. Michele Lindsay was a TapRooT® Instructor for over a decade. But she now is a performance improvement coach at a healthcare facility. But this year she will be coming back to the TapRooT® Summit and is presenting a new course on creative corrective actions using Dr. Edward de Bono’s Six Thinking Hats™ techniques.
That’s a lot of training to choose from! But don’t wait too long to register. Seats are limited in these courses and we want you to get your first choice!
Additionally, you get a $200 discount on the training when you also attend the 2015 Global TapRooT® Summit. For more Summit info, see:

Monday Accident & Lessons Learned: Crane Accident at Tata Steel Plant in the UK brings £200,000 Guilty VerdictMarch 16th, 2015 by Mark Paradies
Tata Steel was found guilty of violating section 2(1) of the Health and Safety at Work etc. Act 1974. The result? A fine of £200,000 plus court costs of £11,190.
HSE Inspector Joanne carter said:
“Given the potential consequences of a ladle holding 300 tonnes of molten metal spilling its load onto the floor, control measures should be watertight. The incident could have been avoided had the safety measures introduced afterwards been in place at the time.”
The article listed the following corrective action:
“Tata has since installed a new camera system, improved lighting, and managers now scrutinise all pre-use checks. If the camera system fails, spotters are put in place to ensure crane hooks are properly latched onto ladle handles.
Here are my thoughts…
- Stating that corrective actions would have prevented an accident is hindsight bias. The question should be, should they have learned these lessons from previous near-misses?
- Reviewing the corrective actions, I’m still left with the question … Should the crane be allowed to operate without the camera system working? Are spotters a good temporary fix? How long should a temporary fix be allowed before the operation is shut down?
- What allows the latches to fail? Shouldn’t this be fixed as well?
What do you think? Is there more to learn from this accident? Leave your comments here.

Bridge strike and collision between a train and fallen debris at Froxfield, Wiltshire, 22 February 2015
RAIB is investigating a collision between a high speed train (HST) and a bridge parapet which had fallen onto the railway at Oak Hill, an unclassified road off the A4 on the edge of the village of Froxfield, between Hungerford and Bedwyn. The accident occurred at about 17:31 hrs on Sunday 22 February 2015, when the heavily loaded 16:34 hrs First Great Western service from London Paddington to Penzance (train reporting number 1C89) hit brick debris while travelling at about 90 mph (145 km/h). The train driver had no opportunity to brake before hitting the debris, and the impact lifted the front of the train. Fortunately, the train did not derail, and the driver applied the emergency brake. The train stopped after travelling a further 730 metres (800 yards). There were no injuries. The leading power car sustained underframe damage and there was damage to the train’s braking system.
The bridge parapet had originally been struck at about 17:20 hrs by a reversing articulated lorry. The lorry driver had turned off the A4 at a junction just north of the railway bridge, and crossed over the railway before encountering a canal bridge 40 metres further on which he considered to be too narrow for his vehicle. A pair of road signs located just south of the A4 junction warn vehicle drivers of a hump back bridge and double bends but there were no weight or width restriction signs. The lorry driver stopped before the canal bridge and attempted to reverse round a bend and back over the railway bridge without assistance, and was unaware when the rear of his trailer first made contact with, and then toppled, the brick parapet on the east side of the railway bridge. The entire parapet, weighing around 13 tonnes, fell onto the railway, obstructing both tracks. This was witnessed by a car driver who was travelling behind the lorry. The car driver left his vehicle to alert the lorry driver and he then contacted the emergency services by dialing 999 on his mobile phone at about 17:21 hrs.
RAIB’s investigation will consider the sequence of events and factors that led to the accident. The investigation will include a review of the adequacy of road signage and the overall response to the emergency call made by the motorist who witnessed the collapse of the bridge parapet. It will identify any safety lessons from the accident and post-accident response.
RAIB’s investigation is independent of any investigations by the railway industry or safety authority.
The RAIB will publish the findings at the conclusion of the investigation on it’s website.
Whenever you deal with a hazard, someone has to decide how many safeguards are enough.
Moving oil by tank cars is probably not the safest method of transporting oil. Pipelines are probably preferable. But pipelines don’t go from every oil source to every refinery. (And getting new pipelines permitted can be difficult – as we know.)
Rail accidents bring up the question … Should we be working on preventing the root causes of rail accidents OR should we be coming up with better safeguards (better rail cars) OR should we be working on getting more pipelines built as a longer term solution?
Here’s the article from the Journal News that got me thinking about this issue:
What do you think? What corrective actions would be SMARTER and what is enough? Leave your comments here.

For those in the Northeast who have had to deal with so much snow, shutting the office because of 3 inches might sound stupid. But in Knoxville, we aren’t used to snow and the hills make getting around hazardous (especially when so many people never learned to drive on snow and don’t even have all season tires).
So … SI will be closed today. Hopefully this won’t be like the ice storm last week (three days out with hazardous conditions).
