I'm not sure I agree with most of this at all. Yes Signal Failures are incredibly irritating and a few could perhaps be avoided. But things do break down such is life. Computers Crash, Cables degrade with changing weather and sometimes human error and poor judgement causes "unforeseen consequences". We are only human and it happens.
I am very much minded of the Southall Rail Crash and the role that the
OHLE▸ (Overhead Line Equipment) played in the accident. Great technology implementation for electric trains. But I don't think anyone could see the potential for such an outcome with the Supporting Stanchions. Thankfully the
UK▸ has a very reasonable safety record when you look at the amount of fatal road accidents that happen in just a day alone...

Trains also travel much faster than Cars/Lorries/Buses etc
I must say though that as
FGW▸ are now paying significantly higher track access charges. Then as FGW I would seriously be taking Network Rail to the cleaners considering the recent signalling issues. However I must also stress that with the fail systems in place, I would rather a significant delay and be safe, than risk proceeding but there being a dangerous risk of something going terribly wrong.
Finally, some of the public and the media especially seem to take very dim views on Planned Engineering Works, Emergency Engineering Works and Delays as of the result of Track Side Equipment failing on the railways. So roads are never closed for roadworks, Accidents never happen on the highways, Road Bridges are never closed due to high winds, Roads are never closed to hold a street market on the 3rd Sunday every month. Lorries never break down on Junctions. Traffic Signals never break down in the rush hour. The list is endless.
I would rather be stuck on a train, than in a traffic jam on the motorway any day of the week. At least you can get up and use the toilet, get a cup of coffee etc. Also, who compensates you for a 3 hour traffic jam vs. a 1 hour train delay?!?! ;-) Don't see any reductions in Vehicle Tax I'm sure...
Whilst I may be being overally harsh here. I certainly think your
OP▸ was made in frustration which is completely understandable. But as trainer says. Delays to travel no matter what method (even walking) you use are all very possible to delays and you just need to take it on the chin sadly. I don't like saying that. But I get stressed out over more than enough things as it is. I don't need to be contributing to that level any further whatsoever!
I hear an announcement that the train is going to be delayed by an hour and watch most people sigh or get annoyed. But why the need? Yes you can scream and shout at the staff, but is that going to get the train moving any quicker? Fact is, not alot can be done. I personally on hearing these announcements will go and order at the Travelling Chef if I can, or get my laptop out if it's a short journey and occupy my time that way. No point stressing over what is out of my control. The only time I would approach staff with a concern is if the delay was likely to mean I was going to miss last connection of the day. On occasions when this has happened, I've got the staff at the station to endorse my ticket before I've even gotten on the delayed train and then can deal with it as I conclude my journey.
