We agree on all the above. Here is the but:
Say for example an incident, let's say a bridge bash, has taken place. Trains are trapped, and are held at protecting signals. Passengers are told a bridge examiner is on the way, but it's unknown exactly when he/she will arrive. As it turns out, the examiner gets stuck in traffic and takes longer. When he arrives, the bridge is in such a poor condition that it requires an engineer. So, there is more delay.
The police also get involved, as it turns out the lorry has many defects and the driver comes from outside the UK with insufficient paperwork.
In the meantime back workings are getting delayed because train crew are trapped on the trains. Controllers are weighing up, whether it is worth getting out replacement buses. Station areas become congested as trains begin to become trapped in stations, and train crew/signallers are working out whether to detrain and shunt the stock, but that depends on having enough drivers in place to do this, and others are trapped by the blockage. More trains arrive, and Drivers are leaving trains in platforms with no driver to replace them.
The engineer arrives at the line and considers whether to pass the line for 5mph. In the end, he clears it and replacement buses are cancelled.
The first train is cautioned through, but the bridge condition gets worse. Operating staff decide to put in single line working. In order to get the staff, 2 ground frame operators are required, a pilotman and several handsignalmen (some for the level crossings en-route).
After 30 minutes of frantic calls, sufficient passed staff are unable to be found, so diversions are set up, and bus replacement services are once again ordered for the intermediate stations. Due to the number of people trapped, buses are unlikely to be sufficient in any case, so passengers are directed to other line and passengers are asked not to travel or delay their journey.
The contract bus provider has by now, sent his coaches out on a schools contract. So even more need to be brought from outside the area, and taxis ordered. Already 20,000 people have been caught on standing trains, and another 15,000-20,000 people are at stations waiting for trains. They all want information, for their needs, and station staff are bombared with questions, each taking many minutes to deal with.
So what can we conclude:
1) the situation is ever changing, and what seemed like a good plan initially, changes. Hindsight is a wonderful thing.
2) passengers have individual needs, and the logistics of dealing with them all can be challenging, especially if they are disabled, elderly, have specific travel needs (like advanced tickets or booked seats) or are aggressive.
3) usually the information comes from signallers and in some cases controllers, which is relayed back to passengers, but those staff are busy speaking to other staff, dealing with out of course working, and changing platforms to minmise delay and filling in necessary paperwork.
4) It is impossible to give accurate delay or platform information, insomuch it may change again.
5) It is not always possible to source qualified staff
6) It is not always possible to provide replacement transport, at least straight away
7) There might be information that could alarm passengers
That's just a really simple example of what can go wrong, the root cause being outside the railway's control. Usually everything is done to help passengers, but there are going to be people that will not be satisfied with the response, including management who very often call an inquiry to find out indivdual actions and try and learn from each incident, which tend to be dynamic, complex, different, and require extra resources, or involve third parties.
Some incidents are multilayered. For example, a bridge bash, a suicide and a track circuit or train failed. Sometimes incidents happen 20-50 miles alway, which then affect the resouces or delays of trains already caught up in trouble.
Most enthusiats have a very simplistic notion of the way the railway really works, for members of the general public their knowledge is minimal at best, the same as it would be for airlines, hospitals, councils, the police, so on and so forth.
It's very easy to conclude in newspaper articles people are not doing their job properly, when you have little knowledge of what you are talking about, or haven't experience the reality of the situation.
Again, it's not to say things cannot be improved, they always can.
The trouble with the railways, is people always think they know how to run them better than the people that do, based on many simplistic notions. And people are very quick to pass judgement. They simply do not understand the logistics for the most part.
Of course passengers should be given information and the railways should be customer focussed, we can all agree with that. We all agree staff hiding, unless there is a specific threat, is not acceptable.
But what many will never understand (or don't want to understand) is the reality and the multi-layered problem solving that needs to take place before any information is given, all with seconds or minutes to decide, involving many people with sometimes mind-boggling logistics.
