Yes, that's the latest problem to hit the unfortunate GOBLin.


"Eight bridges were also damaged"

Holy crap!

Whatever if any warning systems there are on the train to warn the driver
of a possible derailment clearly didn't work if it took him 2 miles to
notice since if the freight on the Goblin runs at the same speed as the NLL
then it was probably trundling along at under 30mph so could have stopped
fairly quickly.



Is there any such warning system?


Don't know. But don't freight logos have wing mirrors so the driver can spot
any problems down the train like a wagon out of line or dust being thrown up?



That's fine if you're on dead straight track. Add in a curve, particularly
reverse curves, or lineside structures/foliage, and your chances of seeing
the back of the train are minimal.

The mirrors on 66s were installed for assistance during shunting rather
than to see back down a train in motion, IIRC.

I don't know if there is anything on board, though I would imagine that
line controllers could see that and be able to call a Code Red.


Signallers will notice when trackside equipment is damaged by the train,
though the first few faults are likely to be assumed to be just normal
faults, until a pattern emerges.

What's a code red? The UK doesn't have such things as a general,
railway-wide scheme; though it may have specific local meaning.

The Alaska Railroad has something in the event of tracks being somehow
compromised.


How does it work?

Sorry, this would be an order to all drivers to come to a safe stop and
stay where they are.

They use that on LUL, though I realise that this is a different entity
to NR.

I don't know.
