Trivia: Highest location that each TOC/FOC serves or passes

[Man of Kent]

Entrance to Polhill tunnel ( London end )140 m apparently

I think that is the height above the tunnel, rather than the height at the bottom of the cutting.

An older OS map available on the NLS website shows a benchmark on the road of 438.4 ft

Side by side georeferenced maps viewer - Map images - National Library of Scotland

which is about 133m.

What about the Tunbridge Wells/High Brooms area?

Further south near Wadhurst perhaps.

London Overground should definitely be Parliament Hill summit, between Gospel Oak and Hampstead Heath. Ground level is indeed higher between Hampstead Heath and Finchley Road & Frognal but the tunnel means that the overground doesn’t follow that.

I stand corrected !

Looking at LNWR but removing WMT (so WCML services and branches ) where would the highest point be?

Are we including Liverpool-Birmingham? Coseley is 153.6M

I am not convinced, though it is quite hard to follow the contour lines on the Ordnance Survey. I think that Crystal Palace is higher than Gospel Oak, despite the station being at a tunnel entrance. I've visited both many times over many years.

That’s interesting - I just assumed Parliament Hill because of the number of times I’ve seen freight stall there! But you may be right… I don’t know Crystal Palace… other side of London to me!

I'm going to suggest that Chiltern's summit is somewhere around Saunderton, at about 120m

Just checked.
On the Western, just north of Saunderton (Bledlow-cum-Saunderton ridge) is 132/133m above sea level.
But on the Met line, just north of Great Missenden, Cobblershill Lane bridge between Little Hampden and adjacent to the HS2 works is 159/160m above sea level.

I can’t vouch for its accuracy but I found this on line

It suggests 95m for the summit of Brentwood bank slightly higher than Elsenham
94m and the eastern portal of the Stansted airport tunnel of 93.6m!

But where is the Brentwood height measured? The summit at Ingrave is in a cutting, whereas Elsenham is not.
