Your explanation whas complex, but I think I understood the basic (serious) issue. I have also heard NR» say that some of their "new" working practoces are simply things that have been used for ages and with safety in some parts of the country.
I am not in a position to judge what is and isn't safe either in theory nor especially in practice. What we need really is the safety regulator to be sufficiently well informed, experienced, independent and robust for passegers like me to be able to trust it to do that job on my behalf.
I'm not sure that it is correct to say that the T3 altered working practices have been used in other parts of the country. It has been trialled I believe but as I understand it the PWay men refused to work as there was also the possibility of trains being missrouted in error towards the possession. Again once the train ran over the detonators and saw the PLB it would come to rest before reaching the worksite. The misrouting of trains towards possessions hazard can be overcome by other means but the possibility of work trains running out of possessions is rather more intractable. I rather doubt that there is anyone at
ORR» with practical experience of T3 possessions and their operation, therefore they are accepting the change with caveats to cover themselves and distance them from any accident thereby caused. Any practical railwayman can see the hazard.
We do also have to aviod falling into a "safety at any cost" arguement. I am not saying that we are there yet but it is possible to make the railway so safe that it becomes unaffordable which forces potential customers onto much more dangerous alternative modes of transport. I read an article by a H&S▸ expert once who argued that the Hatfield crash killed 4 people but that the reaction to the crash caused speed restrictions to be imposed which forced people off the railway and onto the road where an estimated 200 people were killed.
How many lives wudl have been saved if the money spent on TPWS▸ has instead been used to clean hospitals?
The Hatfield crash did cause a modal shift to road transport both by the passengers of their own voilition and the
TOC▸ 's using rail replacement coaches and I can remember some passengers and traincrew being injured in a pitch in on a coach on the A38. As far as Railtrack was concerned however the risk was minimised as the injuries etc did not occur on their infrastructure. 'Not on their infrastructure' being the key words.
The formula for cost benefit has been applied to railways before in terms of ^ per life saved, which is why you got
CDL▸ on slam door coaching stock instead of national implementation of the
ATP▸ system still used by
FGW▸ . However I do not subscribe to the view that removing basic safety measures that have been in use virtually since the accident that contributed to the early demise of Charles Dickens merely to save money are they way forward. Particularly since to my certain knowledge they have been found to be worthwhile in preventing accidents.
