Interesting, is this a peak time-only thing? That would explain why I've never noticed. I wish they still ran all the way to King's Lynn
Yes it’s peak times only. I can’t even see GBR a few years down the line operating to Lynn. The GN services were always far busier.
Up to the 1980s Kings Lynn-London trains ran/to from Liverpool Street, and it was also the primary route for Cambridge. Between 1978 and 1988 there were no through trains Cambridge-Kings Cross, never mind Kings Lynn.
That all changed in the early 1990s with electrification north of Cambridge and the opening of the Stansted Airport branch.
When through services between London and Kings Lynn were resumed in 1992 they were mostly to/from Kings Cross, but a few peak time Liverpool Street trains were resurrected, mainly for commuters going to/from City of London financial district. They were retained at privatisation but usage dwindled over time, it was quicker to get to/from Liverpool Street going via Kings Cross.
After privatisation the Liverpool Street-Kings Lynn trains got very inefficient and expensive to operate because only the franchise running Kings Cross trains had drivers at Kings Lynn. Drivers of the Liverpool Street trains were based at Cambridge and needed ECS or taxi moves to balance up.
I think the Liverpool Street-Kings Lynn trains were never restored after the covid pandemic. As far as I'm aware class 720s have never worked to/from Kings Lynn.
Kings Lynn now has a regular interval 2tph peak time service, all with Kings Cross trains. The draft 2025 East Coast timetable shows that this will continue into the future.
What I find interesting is that Cambridge to Norwich figures are 7 times greater than Cambridge to Leicester. Leicester is slightly further but also significantly larger than Norwich, but both have direct trains.
This neatly demonstrates my point that the shorter distance East Anglia flows are far more important than the longer distance flows. Many more people want to travel within East Anglia than to get in or out.
I find that interesting that a quarter of passenger from Cambridge travel to Manchester Victoria rather than Manchester Piccadilly. I often do it because it’s actually quite straightforward with a change at York or Leeds but I’m surprised it’s as many as it is as a proportion.
I was intrigued by this too, and have been trying to work out what is going on. I suspect that the data is for "Manchester BR" and there is a simple %age split between Piccadilly, Victoria and Oxford Road. The same is possibly happening in Liverpool with Lime Street and Central.
simply to extend the London to Braintree’s westwards to Great Dunmow and Stansted Airport
This is definitely not simple. Much of the old trackbed is now the Flitch Way, and in Dunmow the route has disappeared, partly through road construction and partly through demolition of the viaduct over the River Chelmer. That's without even thinking about how to get into the airport from that side.
I agree with you but presumably the opposite happens with Gatwick where trains do continue on to Gatwick. Does that set up course problems
You make a valid point about Gatwick. Fortunately the Thameslink class 700s are 8tph to the core and particularly well designed for airport traffic, plus another 8tph to Victoria. Whereas Gatwick has separate options for the City and West End, both at 8tph, at Stansted everyone for London is on the same train, and it is only 4tph.
