I'm sorry, but I really don't see why you feel that you should make the statements that you have. My OP was placed in good faith, I find this response to be extremely "disappointing", to say the least.
Is a member of the rail using public not allowed to make a comment that a train appeared to be going "VERY fast" ? My two Mk 1 eyeballs would certainly not be accepted by any constabulary as proof that any motorist was exceeding the speed limit, so why should this be considered the case when applied to a train ? As several of the follow up posts have quite correctly said, it is easy to misjudge speeds - this train certainly was incredibly noisy - and I don't have much experience of judging Class 66s hauling a heavy container train passing by (at 75 mph ?) a few feet in front of me.
I did
NOT say anywhere in my post that I thought the driver was acting improperly - the response seems to suggest that he might have been.
If indeed, the train WAS exceeding its speed limit (do trains have data recorders ? I don't know - [Having just Googled OTMR it appears they may well have]) surely I should be praised for my actions - NOT be told to withhold evidence in case a rail employee was misbehaving and might get into trouble?
"Rumour and conjecture" do not come into it. If a rail employee was breaking the rules, "serious consequences" should follow.
