The curve ends at 24m 15ch, but there is a very slight one marked at the north end of Three Bridges, radius 5450m(?) at 29m 5ch to 29m 15ch according to the 5 miles.I concur with that analysis, maybe just over 7 miles dead straight.

I make it about 14 miles, with the former alignment beyond Firsby South Jn towards Burgh-le-Marsh continuing along the same straight line for another couple of miles.It`s considerably more than 10 miles. Probably over 15.
Correct although it is so very slight on the entry to Three Bridges. It could be considered almost dead straight to some degree...The curve ends at 24m 15ch, but there is a very slight one marked at the north end of Three Bridges, radius 5450m(?) at 29m 5ch to 29m 15ch according to the 5 miles.
I would contest that 'dead' straight means 0 curve, and that something is either dead straight or it is not. I agree it's almost straight, but by the best definition we have (the railway curvature records), it is curved.Correct although it is so very slight on the entry to Three Bridges.

If it was perfectly and absolutely straight, including with respect to its vertical layout (which I suspect is not usually included in what people mean when talking about straight track), as measured by a light beam, then it would be lowest in the middle and highest at the ends, relative to the curved earth.Interesting, thanks.
I'm guessing we're unlikely to find anything above the 20-odd miles of Selby to Brough?
Wouldn't it gain height towards the middle then lose the same amount to be back where it started (purely curvature of the earth related, not any other gradients)?
The line actually has a few sweeping curves between York and Darlington. I think the longest straight bit is roughly from the northern by pass bridge at York to Raskelf. I used to live in the middle by the 7mile (from York) post. I think the distance is 12-13 miles. Could be the longest 4 track straight?Always the racecourse between york and darlington
There are long straight sections with a few small curves on that section and am aware of one through Penshurst Tunnel.I vaguely remember that my Guinness Book of Rail Facts & Feats in the 1970s gave Redhill-Tonbridge an honourable mention as it was almost dead straight between the two junctions at either end with only minor deviations - and it passed through five stations en route.

Around Drem its only really straight for about 2 miles between Drem Jn and Ballencrieff.Drem to Inveresk?
I’d say that between Godstone and Dwelly Lane there is an obvious curve on satellite view even before you apply a straight edge. But Streetview also shows the curvature quite well looking east from Gibbs Brook Lane Bridge (near Crowhurst).On Google Maps it's two sections of...
Near 6 miles between Hartspiece Rd bridge exiting Redhill & Dwelly Lane (where the line curves slightly)
Near 9.5 miles from Grants Lane to the line passing under the A21.
Being pedantic - a very wise old Pway engineer once said to me "There's no such thing as a straight, its just a curve of infinitely flat radius" - however the straight north of Carlisle at Kingmoor is pretty long, as you look north you can see a train way in the distance and it disappears into a dip and then reappears! (my guess would be around 5km - but I don't have access to the NR 5mile diagrams)Hi, I am wanting to know any sections on the UK rail network that are purely straight (almost perfectly?), anything longer than a mile would do, though what is the longest? I can think of an example being just west of Law Junction to just west of Shieldmuir which is about 2.7 miles of straight track. Are there any other sections on UK network with really long straight sections of track? Especially ones where there is a spotting location you can zoom with a good camera miles away and see the train coming on a clear day
In the same general area, ISTR that the old Caledonian main line between Perth and Forfar had some fairly long straight stretches....or so it seemed when I covered it in the front of a DMU on a railtour in 1982.Closer to home for the OP, Glencarse to Longforgan (between Perth and Dundee) at around 8 miles.
A bit less than 5 miles, I think, there’s quite a significant curve west of Grange?Closer to home for the OP, Glencarse to Longforgan (between Perth and Dundee) at around 8 miles.
