I suspect one reason there has never been a revival of the
service between Chingford and Stratford despite the new
station in Leyton is that the Highams Park level crossing would
become even busier and traffic chaos would inevitably result.

with 5 times as many cars, travelling 5 times as many miles, I find

national. In London and the SE the changes have been greater.

That level crossing model, while normal in the 1960s, largely went out
long ago. So signalling is as likely as not automatic or controlled by
route setting. 5 crossings are supervised from Cambridge PSB by CCTV.
Almost no crossing gates require a signalman to come down from his box to
open the gates now.

Littleport station crossing!

With an underpass like at Ely!

Don't mention Ely! (You'll annoy Basil).

But the underpass is even lower. So a van like this probably too high:

How much traffic does that crossing get?

Very little. Since the bypass (a while ago now) it's on a road
essentially from nowhere to nowhere.

2.51m at Littleport compared to 2.7m at Ely. That van would just about get
under judging by the amount of clearance visible there. Although judging by
what's on Google Streetview, their car probably couldn't get under it.

Very little. Since the bypass (a while ago now) it's on a road
essentially from nowhere to nowhere.

So it comes low down the priority list for replacing the gates,
unsurprisingly.

You reckon there's 20cm extra clearance here - really??

judging by the amount of clearance visible there. Although judging by
what's on Google Streetview, their car probably couldn't get under it.

The best I can find is that the streetview cameras are "at 8.2ft". It's
not clear if that's the height of the lens, or perhaps the lenses are at
8ft and the top of the camera housing at 8.2ft.

That's so close to 2.5m it's not obvious which measuring system they
were designed for.

But when this last came up I mentioned that same view above, which is
pretty much along the line of the roof of the white van, so I'm inclined
to think the 8.2ft/2.5m is the lens (despite being designed in
imperial-measuring USA), and hence the top of the housing is more like
8.4ft = 2.6m

I see now. I was going by the van body and reckoning that the view showed
the minimum bridge height. I didn't notice the things on the roof, so no,
there isn't another 19cm there.

2.5m = 8'2½". It's the maximum width of buses (or was). I suppose the 2.51m
on the sign would be 8'3", what the other sign on the bridge shows.
