Allow me to tell the story.
Story goes is that the signal man couldn't set the siding signal to clear for the train to proceed onto the mainline, so he told the guard that it wasn't working and that he'd give a hand signal to proceed. Guard relayed this to the driver. Driver proceeded to take the train out of the siding, without checking the road... and then derailed his train on the catch :roll: trap points.
Not only did it require for the loco's tender to have the water pumped out, but there's severe damage to the tender's brake bars, and a gas axe had to be used to separate them; and the TPO's the loco was attempting to pull out have had their emergency brakes applied.
Now, forgive me for saying it, but surely when emerging onto a mainline, even if the signals are clear, a staff member should normally be at ground level near the loco to check the track setting and also for approaching trains or runaways?
The loco's tender suffered damage to it's brake rigging; the video even shows some of this. The tender was emptied of water, before a gas axe was used to separate the loco and tender. My mole tells me the loco wasn't placed back on the track till late evening; 9PM i think was the time he mentioned.
Lastly, the TPO set was juddered so badly that it's emergency brakes applied, and until these are taken off, they cannot be moved. The track also suffered severe damage, and near enough ALL the (concrete) sleepers around the catch point now need replacing.
P.S. The loco's first whistle was to say it was beginning moving, the second to say it was a PSAD manoeuvre.
