Two years later, it is reported that UK (United Kingdom) infrastructure is at risk of russian, or russian inspired hacking attacks, this being in retaliation for the UK supporting Ukraine.
https://www.bbc.co.uk/news/articles/ceqxezer7nqo report here.

The main concern appears to be cyber attacks affecting electricity supply, but oil products distribution would also seem to be a risk.

When I saw the "No Fuel" sign outside our nearby Tesco filling station, I thought this had started - not that I care. But it was just a hole that had appeared on the forecourt somewhere. Until fixed, tanker deliveries could not be made.

Hmm.  Roll Eyes

A random sink hole appearing (or, more accurately, disappearing) on your petrol station forecourt is not really what you want?  I'd be straight on to the surveyor's department, regarding the searches they did before I bought the site.  Shocked

William Huskisson MP (Member of Parliament) was the first person to be killed by a train while crossing the tracks, in 1830.  Many more have died in the same way since then.  Don't take a chance: stop, look, listen.

I don't think it was of epic proportions, and probably would not qualify as a sink hole. Whatever it was, and I have bought only 5 litres of petrol in 15 months so do not have first hand knowledge, it was enough to put the tanker driver off unloading. There is no history of mining in the area.

Sinkholes, of whatever size, don't have to be caused by mining: natural running water underground can cause them.

Yes, and also running water caused by man. A defective drain, sewer, or water supply pipe can cause a sinkhole.

A proper intercity train has a minimum of 8 coaches, gangwayed throughout, with first at one end, and a full sized buffet car between first and standard.
It has space for cycles, surfboards,luggage etc.
A 5 car DMU (Diesel Multiple Unit) is not a proper inter-city train. The 5+5 and 9 car DMUs are almost as bad.

From the BBC» (British Broadcasting Corporation - home page):

Sinkhole gets bigger as storm delays homecoming



A giant sinkhole that forced residents from their homes is getting bigger.

The void emerged on Nant Morlais in Pant, Merthyr Tydfil, on Sunday and was said at the time to be 9-12m (30-40ft) deep and five metres (16ft) wide.

There were high hopes residents would be able to return to their homes soon.  But Merthyr Tydfil council confirmed that idea was now on hold.

It said bad weather meant there was now more water in the chasm and that Welsh Water had had to stop work so a crane could be brought in to stabilise it.  Pumps trying to divert the river were struggling to cope, said the authority.

"As of this morning, the sinkhole has increased in size," a spokesman said. "Unfortunately, this means that we are no longer in a position to allow householders from the lower end of the cul-de-sac to return home safely, possibly until early next week.  However, this timeline will be heavily reliant on weather conditions over the weekend."

On Thursday night, a number of roads were closed - the A48 Severn Bridge between Wales and England because of strong winds, and the B4242 between Resolven and Aberdulais in Neath Port Talbot because of flooding.

The A48 between the Pyle and Porthcawl roundabouts in Bridgend county was also shut because of a fallen tree.

Meanwhile, National Grid is reporting that more than 1,700 customers in south and west Wales have lost power, while localised power cuts have also been reported in parts of north Wales.

An amber warning for wind has been issued for parts of the UK (United Kingdom) with the arrival of the fourth named storm of the season.  Storm Darragh is expected to bring gusts of up to 80mph (128km/h) late on Friday and into Saturday.

The warning for "potentially damaging" winds is in place for the west coast of the UK from South Ayrshire in Scotland, through Wales and down to Cornwall, as well as in Northern Ireland.  It is in place on Saturday from 03:00 GMT until 21:00.

On Thursday, the Met Office issued yellow weather warnings for rain, external and wind, external that covered Wales and other parts of the UK.  Natural Resources Wales currently has a number of flood warnings and alerts in place.

Has a sink hole ever appeared below a railway line?

There must be many locations where running water could potentially cause a problem.

There have been some - sometimes blamed on badgers.

They have been mentioned here on the Coffee Shop forum in the past - I'll do some digging (so to speak)  Roll Eyes

Up near Dalton-in-Furness, in Cumbria, a Furness Railway locomotive lies to this day in one - entombed for ever.

On the topic of the Nant Morlais, Pant, Merthyr Tydfil sinkhole, the local authority has been providing updates - the culprit is that the little estate there is built on made ground, with a culvert beneath to carry the occasionally energetic mountain stream. On November 24th, some residents thought that the rumbling noises were thunder, but the source was a progressive collapse of the culvert after the heavy rain then, the void taking six days to propagate to the surface.

This board is currently being revised and split into two new boards, covering related rail, public and other transport issues which may be of interest, either within the UK (United Kingdom) (including journeys to and / or from the UK) or other such issues / incidents which occur overseas
