Clue: it lies within the M25.

I believe that includes the only ever railway swing bridge. But that
isn't in use in that function any more.

Nope. The Oxford Companion to British Railway History says:

# Opening bridges were built across some navigable waterways,
# allowing shipping to pass. They were usually swing bridges,
# like Thowse Bridge, Norwich (one of the earliest), Selby over
# the Yorkshire Ouse, Hawarden across the Dee near Chester, and
# one at each end of the Caledonian Canal. Scherzer rolling-lift
# bascule bridges replaced earlier swing bridges at Carmarthen
# and across the Trent at Keadby ...

Incidentally, remember the Amtrak disaster around 10-15 years ago
where a barge went off course and collided with a bridge, which
then collapsed under the next train to come along? According to a
TV show I watched recently, that bridge was built as a swing bridge,
but the railway eventually decided not to install the motor, and
used it as an ordinary bridge. However, the show said, they
neglected to rigidly attach the moving span to the abutments, and
that's why the barge collision knocked it out of position so easily.

Like the bridge over Alresford Creek, on the Brightlingsea to Wivenhoe
railway, a mile or two from where i grew up. It was demolished long before
i was born, but i remember being told about it.

Nope.

Indeed, far far far from "only".

Trowse (note spelling) is still in use, and has a 25kV overhead power
rail.

Selby over
# the Yorkshire Ouse,

That's still there as well, though it's no longer on the ECML. At one
time the tracks had four rails each, so that the point blades could be
on the same side of the bridge as the rest of the interlocking, even
though the divergence was on the other side.

[There have been swing bridges where the signal wire "pull" actually got
transmitted across the bridge to a signal on the far side. A neat
mechanical solution.]

I presume you mean the one in Deptford... but there was another a few miles
away, carrying a now-disused railway over the now-disused Surrey Canal.

Deptford Creek. By no means the only swing bridge - others included one over
the entrance to Royal Victoria Dock (to retain access to the Silvetown
Tramway when the North Woolwich line was diverted via Custom House), one on
the surface route over the link between the Victoria and Royal Albert Docks
(retained so that heavy freight trains would not have to negotiate the
gradients into the Connaught Tunnel), and across an Oxford Canal branch on
the entrance to Oxford Rewley Road (LMS) station. I am sure there were many
others, though I suspect Deptford Creek was the first.

The swing bridge deck was still there in June this year, alongside the
'Sheepwash Channel', stuck in the open position and hemmed in on all sides
by new building work.
