The industry cannot absolutely guarantee every single clock is always accurate. That should not be taken to mean that clocks cannot be generally relied upon.
That seems fair enough, but the point was made that they shouldn't be relied upon so I was simply trying to figure out what one could rely upon. Had realised it was such a controversial question
No! we simply must as a business make sure that everything and everyone works perfectly all the time!!
Seems like a sensible aspiration of any modern organization to me (even if it can't be pulled off all the time).
Isn't the advice given to arrive at the station well in advance of when the train is due, and not a minute or two before? If that is done, where is the problem?
No problem at all actually. I was simply trying to discover which time to go by.
Thankfully the clock in my Box is radio controlled so is deemed accurate and I set my watch by it each week.
Sounds like a nifty bit of kit. I had (wrongly) assumed that in our modern world with technology that most station clocks would be radio controlled or accurately synchronised. Radio clocks are hardly new!
None, but sometimes people get delayed. With a walk-up ticket this just means a bit of inconvenience, but when one has an Advance ticket I can rather understand the issue, unless the railway stipulates a minimum time to be on the platform before.
Again, no problem with this. Many terminals already have such notices in places for when doors will be closed, so in a way it's already done.
Actually, I think this issue could well be best solved by recognising that trains are occasionally a minute or two early because watches and clocks aren't perfect, and simply clearly advertising that to guarantee travel you must be on the platform 5 minutes[1] before the scheduled departure time. Trains running earlier than that are near enough unheard of.
That would be 5 minutes by whose watch / clock?
[1] That might knacker connections, but equally I find that the almost universal 5 minutes official connection time is too tight, and most stations justify 10 unless it's a same-platform or cross-platform connection.
I'm probably misunderstanding your point here, but official connection times should reflect the minimum time to transfer from one train to another, not to pad out journeys because the reliability of the service can't be guarenteed.
