Odd you should mention that... this morning one of the Fen Line GN
trains was liveried "Gatwick Express". Which more different to the plain
livery than the straying GA Stansted Express ones (which are at least
the correct side of the river).

Apparently six GatEx 387s have been loaned to GN as temporary 365
replacements.

They are having shuffle, then, because we've not seen 365s on the Fen
line for a couple of years.

Continuing the theme, this afternoon they put a 700/717 (I was too far
away to tell) on an Electrostar diagram from Kings Cross to Ely.

The former, surely?

The train was billed as a GN, and they only have 717s. But Thameslink
runs 700's as far as Cambridge.

Could you see the end, or the length? Class 717s are too slow for mainline
duties.

Is everyone here really so dumb a to think that green electricity
generation and the national grid ought to work by making sure that green
electrons travel from the generator to your home? What was that about
basic physics?

I suggest you have another go at reading what I wrote.

I wasn’t referring directly to you, but to a general feeling in some of the
postings, too diffuse to respond to individually.

Its too late to back pedal now. Your "What was that about basic physics?"
comment was aimed directly at me because either you misunderstood what I was
saying or didn't even bother to read it.

Again no, it was just a convenient place in the thread to hang a comment.
It clearly backfired, but it was not intended personally.

No doubt you think energy companies need your advice as well:

According to my electriconics lecturer mumblety-plus years ago, all
electrons are green anyway:

He explained valve theory as little green ball-bearings bouncing from
Cathode to Anode, an image that has stuck with me ever since.

Cathode ray tubes. Green. Of course!

No, it was some way in the distance, and I was driving.

Class 717s are too slow for mainline duties.

That probably settles it - 717 max speed 85mph, and it's a 100mph
diagram. So a fleet swap.

Hummer have already built 2 large battery SUVs.

By 'built', you mean announced. They're 2023 models, with lots of details
as yet unknown.

And H2 trains makes no
bloody sense whatsoever - just electric the damn lines and if its too
expensive for overhead then they should recind that moronic rule about
no more 3rd rail and lay that instead.

This pilot, like many, demonstrates technical feasability. It does not
even ask the question whether it's viable without a massive subsidy.

Too many fuel cell demonstrators are nothing more than "Look! We can run this
using a fuel cell!". As if thats anything new. They never address the issue
of where the H2 is going to come from and whether its actually any greener than
simply using diesel.

We don't have them here but I seem to remember reading a lot of
complaints about the mess they made of the pavements.

Is there enough spare capacity in the cable for the extra load - the
house's load will have quite possibly increased since the electric
supply was originally connected.

Many people do not have a drive to park in when charging so the supply
is needed at the roadside or in a small car park and has to be one that
can be used by anyone.

That's even deeper, and is typically about as thick as your arm and a
real pig to make connections to.

Surely a cable to a house is not that thick? The house supply is about
half an inch diameter.
