In the month now I have been using Plaistow station every morning, I don't
think I have seen it ONCE announce the arrival of a train.

What's the point of wasting electricity and failing to announce the arrival
of the next train.

Even if it was just a notice to say how many minutes, without announcing
whether it was a District or a H&C line, would be something. But instead it
just says nothing.

But why? Surely in this day and age, it's all computerised? Obviously
there's not some bod with a radio in a shed beside the tracks in East Ham
saying "Hi guys, yep, there's a train leaving just now so it should be with
you in three and, wait a minute, yep it has green coloured things to hang
on to, it's a District, I repeat, a District, over and out."

Theres a computer. So why are these things not linked up? They've got it
working at other stations so why don't they just pick up the feed from, I
don't know, Mile End, and then add VALUE=VALUE+5 to it or something?

Perhaps they really don't know in some stations. Perhaps they're utterly
clueless when a next train is coming. Which scares the pants off me, to be
honest. But let's assume a modicum of knowledge he if they know, and
they MUST know, someone MUST know in a station when the next train is due
and what it is, then bloody TELL US. Because it's a pain in the arse.

In the meantime, they're on day and night, wasting electricity (that we're
paying for, one way or another) and doing jack diddly.
