Help and advice on buying property along the train line into London St Pancras & the City
The Midland Main Line runs up the eastern side of the county, and like every railway round here it goes by several names. People call it the Bedford line, the Kettering line, the Corby line, or simply the St Pancras line, depending where they get on. Some call it Thameslink, which is half right and matters more than it sounds.
It is the quieter of the county’s two London routes and, for a certain kind of buyer, the better one. Wellingborough, Kettering and Corby all sit on it, with Market Harborough at the top and Bedford below.
What makes this line different is where it puts you. The West Coast line delivers you to Euston and stops. This one carries on. St Pancras sits alongside King’s Cross with six underground lines beneath it and the Eurostar upstairs, and at the Bedford end the Thameslink service runs straight through the middle of London to Farringdon, City Thameslink, London Bridge and on to Gatwick without you changing at all.
If you work in the City, or south of the river, or you fly often, that is not a detail. It can be twenty minutes of your evening. If you already know which station you want, Corby, Kettering and Wellingborough goes into those three properly. If you may be on the other line, Living on the West Coast Main Line covers the western side of the county, and Northamptonshire for commuters sets out all the routes together.

Stacks Property Search’s Insider Guide to living on the Midland Main Line.
The Midland Main Line, though you will rarely hear it called that. It is the Bedford line, the Kettering line, the Corby line or the St Pancras line depending on who is talking. All the same railway.
The thing worth understanding is what happens when you arrive. St Pancras is not a terminus in the way Euston is. It shares a building with King’s Cross, sits on top of six underground lines, and has the Eurostar running out of it, so getting anywhere else in London or to Paris and Brussels starts from where you are already standing.
Then there is Thameslink, which is the part people miss. Bedford is the northern end of it, and Thameslink does not stop in London, it runs underneath it. Farringdon, City Thameslink, London Bridge, then out the other side towards Gatwick. For anyone working in the City or south of the river, or flying regularly, that removes a change and a walk from every single journey.
That is the argument for this side of the county, and it is a different argument from the one the West Coast line makes.
It matters differently. On most lines the number people quote is station to station, and on this one that number tells you least.
What actually decides whether a commute is liveable is the door-to-desk time, and the last mile of it is where this line earns its keep. Two people can have identical times into London and completely different mornings, because one of them arrives where they need to be and the other has a change, a walk and a second ticket. Arriving at St Pancras with the underground beneath you, or running through to Farringdon without getting off, takes minutes off the end of the journey that no timetable comparison will show you.
So work out where you are actually going, then work backwards. That is the calculation I do with clients, and it is more often decisive than the headline figure. The detailed times, station by station, are in the Stacks Commuter Bible, which I share with the people I work with.
Broadly, and with exceptions.
Wellingborough suits people who want the shortest journey on this side of the county and do not need a large town around them.
Kettering suits people who want frequency and a proper market town. If your working pattern is unpredictable, it is the most forgiving option on the line.
Corby suits people whose budget is doing the most work. It also has an advantage most people do not think of until they have stood on a platform in the rain: you are almost always going to get a seat.
Market Harborough suits people who want the prettiest option and will pay for it. It is further north than the rest and still quick, which is part of why it has become the London leaver’s choice at this end of the county.
Bedford suits anyone who works in the City, south of the river, or flies often. The Thameslink connection is worth more than the extra distance for those people and worth nothing at all to someone going to the West End.
Whilst Bedford is over the Bedfordshire border I can still help you, and if your search is drifting past the edge of the county more generally, Counties next to Northants sets out what sits beyond each edge and who knows it properly.
This side of the county is where the value sits, and it is the least understood part of my patch.
The three Northamptonshire towns each have a genuine period core and, more importantly, a ring of stone villages around them that most buyers searching from a portal never surface. That is the gap between what people think of these towns and what is actually for sale near them, and it is wide.
Corby offers the most house for the money of anywhere on either line. Kettering and Wellingborough sit above it, with the villages around both carrying the better stock. Market Harborough is the most expensive of the group by a clear margin, and Bedford prices on its Thameslink connection rather than on the town.
The pattern to hold onto is that on this line the town name tells you very little. Two villages ten minutes apart, both a short drive from the same station, can be entirely different propositions. Corby, Kettering and Wellingborough goes through that in detail.
Quieter than the West Coast, and that is most of the appeal.
Getting a seat is the practical difference. Corby is the start of its service, so you board an empty train. Kettering and Wellingborough are busier but nothing like the crush further west. The trade is frequency: this is not a line where you turn up and expect something within ten minutes, so your day has to fit the timetable rather than the other way round.
The other honest point is that this route has been under long-term upgrade work for years, which brings both improvements and disruption depending on the month. Anyone moving here on the strength of a commute should look at what is planned rather than only at what runs today, and that is a genuinely useful thing to check before you commit to a village rather than after.
By road this side of the county runs on the A14 and the A6, with the M1 reachable across to the west. The A14 in particular is the thing that makes the eastern towns work for people whose journeys are not to London at all.
The stations on this line in my patch, north to south
Five options, and one of them is not quite on the main line at all.
Corby sits on a spur reached through Kettering rather than on the main line itself, which is why it appears where it does below.
Market Harborough
The one Northamptonshire buyers most often overlook, because the town sits over the Leicestershire border even though the station serves a good deal of the north of the county.
Corby
End of the spur from Kettering, so trains start here. Reconnected to the network in 2009 and the newest station on the line.
Kettering
The junction. Both the main line services and the Corby ones call here, giving it the most frequent service of the Northamptonshire three.
Wellingborough
The closest of these Northamptonshire stations to London. Station sits a walk from the town centre.
Bedford
Bedfordshire. The northern terminus of Thameslink as well as a Midland Main Line stop, so services run through central London rather than terminating.
How we can help you weigh up the eastern side of the county
This side of Northamptonshire is the part buyers write off fastest and understand least. People hear the town names, form a view, and never look at the villages around them, which is where nearly all the good stock on this line actually is.
I work only for buyers, never for selling agents, so I have nothing to sell you on any particular town. What I can do is tell you which villages sit within a sensible run of which station, which of them hold their value, and which of the five stations actually fits the journey you are making rather than the one on the map.
That conversation is worth having early. It is the difference between searching a radius and searching properly. Read more about how the search service works, or speak to me about this side of the county.
