Yes these are on the MML from St Pancras to Leicester
Camden Road Tunnel between St. Pancras and Kentish Town (varies - up to 315 yards)
Lismore Circus Tunnel between Kentish Town and West Hampstead Thameslink (110 yards)
Belsize Tunnel between Kentish Town and West Hampstead Thameslink (just over a mile)
Elstree Tunnel between Mill Hill Broadway and Elstree & Borehamwood (1058 yards)

Plus I think there is one at Sharnbrook on the Slow Lines between Bedford and Wellingborough (and also known as Wymington tunnel) (1 mile 90 yards)
Are you trying to avoid (or are apprehensive about) travelling through / stopping in tunnels?Hi guys , does anyone know if the is any tunnels between Leicester and London (EMR Route) many thanks and maybe nuneaton to Leicester? Cheer's
Yeah trying to avoid. Going through tunnels always effects my ear pressure.Are you trying to avoid (or are apprehensive about) travelling through / stopping in tunnels?
Ahh i know about the little one between Edinburgh and Haymarket but apart from that is the no more between Leeds and Edinburgh? And also do you know how long that tunnel is on the Glasgow route and Max speed though it ? Thank you so much h!The xx15 Edinburgh to Glasgow Queen Street goes via Falkirk High, which includes the fairly lengthy Winchburgh Tunnel. Everything out of Edinburgh in both directions needs to use a tunnel of some sort, albeit at slow speeds. Edinburgh to Haymarket is mostly in tunnel.
Leeds to Edinburgh though, it'd just be the tunnel on the approach to Edinburgh IIRC.
I couldn't tell you about the max speed unfortunately - other than that it's fairly quick (I'm wagering near to 90-100mph).Ahh i know about the little one between Edinburgh and Haymarket but apart from that is the no more between Leeds and Edinburgh?

I'm not sure of the highest point, but with regards tunnels, there is Sugar Loaf tunnel and there's a tunnel at Pontarddulais on the HOWL. I can't think of any between Crewe and Craven Arms or Chester and Craven Arms, although someone will have to confirm that. Not sure on lengths of the two I've mentioned either. Hope this helps!Hi guys , bit of a random one but does anyone know the heighest point between Crewe / Chester to cardiff via heart of wales line, this infomation would be appreciated and is the any tunnels? Thank you!

Depending on the precise route, think there's maybe seven tunnels between Chester/Crewe and Cardiff via the Heart of Wales line...
Starting from Chester, Christleton tunnel, between Chester and Crewe stations, is 160 yards.
Llangynllo tunnel, between Knucklas and Llangynllo stations is 647 yards long.
Pen-y-Bont tunnel, between Dolau and Pen-y-Bont stations is 404 yards.
There's also Llangammarch tunnel, between Garth and Llangammarch stations at just 56 yards.
Sugar Loaf tunnel, between Sugar Loaf and Cynghordy and stations is 1001 yards.
Pontarddulais tunnel, between Pontarddulais and Llangennech stations is 88 yards.
And Cockett tunnel, between Gowerton and Swansea stations is 788 yards long.
Summit of the Heart of Wales line is immediately to the South of Sugar Loaf station, at 820 feet above sea level.

Llangynllo Summit is the highest point on the line at 299 metres (980 feet) above sea level. (Source: Wikipedia)Summit of the Heart of Wales line is immediately to the South of Sugar Loaf station, at 820 feet above sea level.

Copy Pit summit. 749ft according to Trackmaps.Hi guys , does anyone know the heighest point between Burnley and York on northen rail? Thank you in advance
That's 228 metres in modern measurements, so not particularly high really. But it is very scenic around that point, and quite slow in places.Copy Pit summit. 749ft according to Trackmaps.
Indeed.there are three tunnels between Carnforth and Barrow
