I’ve not written anything for a while about trains. Thought I’d do something now as a really interesting report was published recently into a collision at Waterloo. People may remember I wrote about the Clapham Junction accident of 12 December 1988. We’ve just passed the 30 year anniversary of it. And lo and behold to mark the occasion we have a report into an incident with worrying similarities. In theory the Clapham Junction accident recommendations should have made this years’ Waterloo incident impossible. The fact therefore that it happened at all raises some serious questions. At 05:42 on Tuesday 15th August this year a passenger train left Waterloo at 15mph. It was routed onto the Up Relief over points 1524 – specifically their “C” end. As the train approached the points the driver saw they weren’t actually set. He applied the emergency brakes but couldn’t stop the train before reaching them. The front carriage went the wrong way over the junction and collided with the freight train stabled on the adjacent line at 13mph. No one was hurt. Not exactly a big deal really, except for the fact that the signal box had all the lights and indications on their panels that 1524 points were set for the Up Relief line. Somewhere between the wiring in their panel, with the buttons they push to set the routes, and the physical motors that push the points one way or the other something was not right. That error had quite small consequences here but it is basically the same type of error as caused the Clapham Junction crash that killed 35 people. Hundreds of pages of procedures exist now to make that error impossible. Clapham Junction was caused by wiring errors in the Waterloo resignalling project of the mid to late 1980s. The latest Waterloo accident was caused by wiring errors in the current resignalling project for the same area. 30 years on and everything needs replacing again. In particular platforms are being extended at Waterloo to allow longer trains to keep up with passenger numbers. This requires moving a lot of pointwork, which in turn requires moving the signals that protect those points and the wires and relays that control those signals. So there was a huge blockade of large sections of Waterloo station and the approach to it in August this year. In order to allow the necessary work to go on in the months up to and following that blockade a test deck was constructed that would simulate the inputs and outputs of the wiring as it was being installed. Spur wires were added in the relay room while testing was carried out so that indications were sent to the test deck. A “principles tester” sat with the deck in Wimbledon signal box. They would call up each one of the numerous routes possible in and out of Waterloo and check to see if the indications received were correct. The points on the ground would not physically move during this. The plan was then that the test deck would be removed when the track was returned to normal operation. When testing 1524 points the principles tester found they did not get detection on their panel. The circuits that showed whether the motors had done their job (or simulated it in this case) were not feeding correctly back to the panel. The principles tester called up their colleague in the relay room – the “functional tester”. The functional tester, in contravention of every principle in the rulebook, went and added some wires to fix the problem. They got detection. The testing was later completed and in the morning of 15th August the track was handed back. However the wires added by the functional tester were added to the bits and pieces remaining in place in the relay room, not to the stuff being disconnected when the test deck was removed. And the wires they added had the unintended consequence of causing C end of 1524 points to give detection when they were only swung halfway across. At that point the motors would stop, leaving the points “split” on the ground but showing as set correctly in Wimbledon signal box. The tester should not have been adding wires at all. One of the conclusions of Clapham Junction was that all resignalling wiring work should be tested by someone other than the person doing it. So no tester should ever make alterations, as how can they then test it. Two electricians were also on duty in the relay room and the functional tester gave evidence that the problematic wiring was actually added by them. They denied it, and the sign in sheet shows they were probably both out at lunch when it happened. When questioned about the consequence of adding the wires in the locations in question the functional tester showed worrying gaps in knowledge. The wiring installed should have been labelled and it was not. When the track was handed back a wire count should have been done – this in particular was a key requirement from Clapham. But the entire exercise of using a test deck, which is accepted industry wide for large projects, makes a wire count impossible as the wiring to put it in and take it out has to remain in place for a long time, and is not shown on the diagram the count is conducted off. The functional tester was not a Network Rail employee. They were employed by an external contractor, whose competency management processes were called into question. Their assessment regime had not picked up the holes in the functional tester’s knowledge. More worryingly it had not picked up gaps in their “soft skills” – i.e. the ability to sit back and have a think before just going and doing whatever worked to solve the immediate problem. The tester had lost their licence to work in that role in the past for contravening signalling standards, and the training plan that allowed them to regain the necessary qualifications hadn’t properly addressed their shortcomings. We have hundreds of procedures, requirements, qualifications, and standards to prevent what happened at Clapham. It shouldn’t be possible for someone with limited knowledge to just walk into a relay room and create unsafe situations. But if the companies assessing those doing that work are deficient then we have a problem. If Network Rail has no oversight over those companies and their assessment processes we have a problem. And if large scale projects are consistently planned on the basis of non-compliance then we have a problem. In their investigation into this the RAIB has made the point that a large part of why the recommendations from Clapham have worked is the industry wide willingness to abide by them. This in turn is driven by some quite vivid memories of the consequences of not doing so. In 30 years that has eroded. No amount of processes are going to do the job without individual and organisational will behind them. It will be interesting to see if near misses are enough to refresh that will. https://www.gov.uk/government/news/report-192018-collision-at-london-waterloo

jobson groeth posted:SYD represent Cargo planes with no windows or livery look weird. I've done a ton of flying over the past three months and will probably do more in the first three months of the new year and I had a question, and this thread seems reasonably apt to ask it. Whenever I'm sitting in the back of the plane, which I prefer because it gets me closer to where the hosts keep the alcohol, I notice before takeoff a smell of fumes in the cabin. It seems like you don't get that when you're sitting in the front of the plane, ie in front of the engines. Am I smelling engine fumes? How are they getting inside the plane?

Jet engines compress air. Some of that compressed air is bled off (“bleed air”) and used to pressurise and otherwise condition the cabin.http://www.askthepilot.com/questionanswers/cabin-air-quality/ posted:You’ll occasionally notice a strong odor when the plane is on the ground—a pungent smell similar to the exhaust from an old car or bus that fills the cabin shortly after pushback. Usually this happens when exhaust gases are drawn into the air conditioning packs during engine start. The wind is often to blame, causing air to backflow or blowing fumes through the pack inlets. It normally lasts only a minute or so, until the engine is running and stabilized. It’s unpleasant but little different from the fumes you occasionally breathe in your car while stuck in traffic.
