I disagree, but much of the interest comes from knowing a little about the local history.
The stretches between Grantham & Peterborough include Careby, Essendine and other places which used to have stations and loops - that stretch was made famous by the Mallard speed record involving blowing its middle cylinder and having to be towed back north again.
These villages are still there, each with a 'Station Road' but no station.
The isolated church at Woodwalton comes with stories of a devastating local plague, and just north is Abbots Ripton where the Newcastle landowner (who's name is attached to my home street) died in the Flying Scotsman crash in the snows of eighteen seventy something. (After which signalling changed forever).
Nearer Retford, there are odd places where you can glimpse Lincoln cathedral on a clear day.
Through North Yorkshire, you can make out the white horse carved into the North Yorks Moors; its fun in winter to guess whether the white soil and any snow will be distinguishable.
Or north of Berwick, you can walk along the narrow sheep trail between the line and the sea for a few miles and reach that abandoned house down in the curve of the cliffs. North of there is the 90degree curve round Ayton House which almost glows red in sunlight, then there's the sad story of the Penmanshiel tunnel collapse and the 'new' diversionary curve round Grantshouses. Between the two is Houndswood where there's a shop which specialises in selling fuchsia plants - that's a word most folks can't spell correctly and a place folks don't stop at, but what an odd and industrial-looking church tower there is there.
Then near North Berwick there's the pyramid-like mounds of Berwick Law and the other one near Haddington (Traprain Law?), the monument over Haddington, and out to sea there's the Bass Rock famous for its puffins and covered with white droppings (and a little lighthouse half way up). These pyramids are said to be volcanic. There's also the island of Fidrie (also with whitewashed light house).
Even in darkness, there are landmarks - I use radio & TV transmission masts as place anchors, with different patterns of red lights on them. There's one on Sandy Heath (east of Sandy, Beds.), two together in County Durham (Pontop Pike & Burnopfield), one in Chatton (west of Chathill, N'land) and one in Fife (north of Longniddrie) which are otherwise featureless at night.
Once you've become used to the tunnels you can feel smug knowing exactly when passengers using mobiles are about to be cut off too!! The Peasecliffe and Stoke tunnels either side of Grantham always come as a surprise!
I could go on, but all these fragments of interest are at their best when you 'discover' them yourself.
Oh, and don't start me on the Highland mainline and speculation about where all those lineside lupin seeds must have come from!
Boring? Never!
