In the diary.

you really have to go on the first day

He may not have put it in the diary for the first day :-)

but surely if the intention is to visit at some time in the future, you
can
remember a more approximate date (August for example) without diarising it

Personally, no. If I want to do something I find it best to get it
into the diary (a) to stop me arranging something else on the same day
by mistake and (b) as an incentive to make it happen. I sometimes
put TV programmes in the diary to make sure I don't forget to watch or
record.

but "catch up" excepted (which doesn't always work) you may only get one
chance to watch/record a TV program

once this museum is open, there are hundreds of future occasion that you can
visit

Yes, I would deliberately avoid the first day. I'd rather go when any early
glitches have been sorted, and it's less crowded.

I'm now puzzled Tim, did you mean I ought to go on the first day or why do
I have to go on the first day?

why are you recording the first day it is opening, if you don't intend on
visiting it ASAP

I'll likely visit sometime in the autumn.

Has anybody here ever ridden the line in its entirety? It doesn't have
any sort of wayside signalling, does it?

Given that the original trains were unmanned, what would be the point of
wayside signalling?

There were some manned, battery-powered trains, however. If there was a
curve in the line that would obscure the line of sight and another train
were stopped beyond the curve?

It shouldn't be there, the battery locos were used during overnight
closed periods or to tug failed trains with the power off.

Also worth noting that the trains could obtain speeds upwards of 35 miles.

The trains were stopped and started by turning the
power off and on on the section of track they were travelling on.

Did power supply from the track feed into a relay for the trains' brakes?

Ov - brakes on/normal (spring brakes), 150v (in station area) 15mph,
206v (approaching station), 440v 40 mph.
[http://www.mailrail.co.uk/operation.html]

What would happen if another, unmanned train were on the track ahead?

You should have a dead section behind it.

Will the tentative journeys on offer run from Whitechapel all the way
out to Paddington via Mt. Pleasant, BTW?

The sorting offices have long been dispersed away from Central London
and well away from the PO railway.

Moving freight between places which are no longer suitable railheads ?

I was thinking more in-city style deliveries. It must take a van about an hour
to cross central london during the day.

Are you proposing to open dozens of new stations?

Yes, it clearly had no remaining use for the Royal Mail.

Cargo also seems unlikely. At best, it could be used for data or power
cables.

I'm assuming the battery locos only ran when the automatic trains were not
running (ie, when track power was off).


Also worth noting that the trains could obtain speeds upwards of 35 miles.

The trains were stopped and started by turning the
power off and on on the section of track they were travelling on.

Not quite.

Quote:
The trains brakes are held off by electromagnets whilst its receiving power
and on the move, but when it hits a dead section of track the train brakes
are automatically applied and held on by large springs.

That's what I actually meant.


What would happen if another, unmanned train were on the track ahead?

The battery loco presumably wouldn't have been running on track sections
occupied by service trains.

Got it.

No, nothing like that. It's just a short demo loop.

What then are the plans for the remaining sections? AIUI, they have
maintained them.

Again, possibly too remote from the supply end for power cables.
For comms, maybe only usable if the two ends are conveniently close to
the existing stations but fibre-optic cables only need a reserved
space on the cable bearers rather than the entire tunnel as would
necessarily be the case with HV cables. BT already has a more
extensive tunnel system.

I could be making a note to avoid it that day as it will be crowded.
