I have quoted the original post in full. Now, in my limited knowledge, I cannot see whether it is speculating about driver error. What I would appreciate is a reply that says a) what the original post means, or implies, b) what other explanations might be possible, and c) a reasonable discussion of any issues that might arise out of this, whether affecting the driver, the design of the bogies, the trackwork, signalling or anything else. This is a discussion board, and people, like me, learn a lot from it. That is why speculation is of use.
It is also, IMHO, excessively paranoid to censor any discussion because someone might have made an error. If an error has been made, then there may well be consequences. I very much doubt anyone would take the ramblings on this board as evidence of anything:roll:
