Train crash in Scotland

Nothing more to add other than the confusion why a train would depart aberdeen around 6:30 when drain covers were popping out the street at around that time..
Because HIND is the operative word in HINDSIGHT...Trains leave stations many thousands of times every single year when it's raining hard. If we stoppped all trains because it was raining, our railway network would be an even bigger shower of sh*t than it is now...........

Route plan of the area where the derailment occurred here....

Scroll down to page 22 which will show where the train crossed over at Carmont to return north towards Stonehaven and Aberdeen. 'DM' is the northbound Down Main, 'UM' is the southbound Up Main.
That’s interesting , the train itself must have been in view from Stonehaven SB when crossing from the UM to the DM.https://www.whatdotheyknow.com/request/315489/resp...

Assuming the box is manned.

RIP the three fatalities.
I'm slightly curious how the decision and approval is given for the train to come back up the line, and at what speed. Once the driver takes it up to 75mph they've got no chance, but maybe it's a balance of 'time at risk'?
How are things like landslips on to lines identified? Presumably areas at risk are checked via periodic surveys and monitored remotely, via CCTV or something? I guess in tandem with weather warnings from the met office.
I'm totally ignorant of the rail world, but interested.

Does it not seem ominous that work was being done in that area, I’ve looked at many photographs and have not seen evidence of landslides maybe it struck something.
It does seem a little odd that the front of the train appears to have been deflected left off the tracks, yet the rear power car (and indeed the rear of the last coach) appears to be still on the tracks past the point where the original derailment must have occurred. Dan_1981 said:
Is it possible for trains to 'aquaplane' or a similar effect?
Doubtful. In heavy rain, it's more likely the water could wash sufficient debris to derail a train. It's possible it could have pushed enough rock and stone to knock the front engine off, but that in so doing the rock was crushed, deflected out of the way of the following carriages.Awful accident though. I'm sure we'll find out the how and why in due course.

As far as I'm aware HST s do not have forward facing (or any) CCTV.
In steep terrain, if there's been any forestry or earthworks done, it is very, very difficult to 100% guarantee integrity of the land. A perfect example of this would be the forest above the A591 by Thirlmere. The forest was thinned, about a year prior to Storm Desmond and the tracks, up and down the hill, formed by the clearance and the access for the forest forwarding machines created the channels which allowed the rain to create landslides which blocked and undermined the road in several places.
Just a few years ago there was a very bad landslip at the northern portal of Harbury Tunnel just south of Leamington Spa, it took months to put it right and there was a 20mph speed restriction on both lines until it was all sorted. I worked the first train through once the line had been cleared of debris and the restriction put in place, I remember looking up at the cutting side as I passed through and seeing a big hole where huge trees once stood.

These ones do have comprehensive CCTV. You can see the forward facing camera in this picture: https://twitter.com/ScotRail/status/12922001583279... - just under the wiper bladeAlso, they run with both power cars running, hence various discussions on places like Rail UK about their horrendous fuel consumption.
