"I don't have the full facts of any of the situations but I'm going to agressively assert my uniformed opinions with some pithy commentary"
Saved anyone about 10 pages of reading there....
Operations teams have a much fuller picture than the general public, they have meetings with meteorologists with very specific forecasts based on multiple weather models with the most likely selected, they are informed of the uncertainty related (i.e. they have a bit more than a cursory look at a weather app) They also have a full picture of assets at risk, they know where there are life expired systems or ones that cannot cope with certain conditions, they know where there is a history of electrical issue, drain non performance, signal box access issues etc. All of these disparate risks are considered when formulating a response.
To claim it's 'throwing in the towel' or 'H&S gone mad' is frankly disgusting against the backdrop of carmont, shap, longbedholm etc. The people involved in these decisions could ultimately be imprisoned.
