Northern Line 1995 Stock Formation

Does anyone know which (half-) set 51551 is coupled with? I seem to have 551 down with both 711 and 552. Does anyone know which is actually correct?

In other words, does anyone have the Northern Line formation list?

Yesterday T155 was N51711+51551S starting from Highgate at 1711.

I always thought that Northern Line coaches were in semi-permanent formation? Is that correct?

If so, what is 552 doing? Is it coupled to 553?

1995 stock has wedgelock couplers between the two units, so are not semi-permanently coupled in the way that the 2009 stock is, but formation changes are very rare compared to stock on some other lines. Most units seem to either be coupled to a consecutively numbered unit or to a 517xx de-icing unit. However 51552 is an exception to this. I've found a video online from June this year, when it was running with 51567.

Also, does anyone know which unit 51532 is formed with? I filmed it earlier this month but forgot to write down the number of the other unit.

N51532+51706S was on T163 this morning.

With one exception (though there have been a few temporary reformations) all 1995 stock is in as delivered formation.

51551+51552 and 51567+51711 entered service as such but we now have

51551+51711 plus 51567+51552

Two trains have just been reformed:

51525 52525 53525 53717 52717 51717

51609 52609 53609 53705 52705 51705


This leaves units 51665 and 51725 unaccounted for. They are probably together, can anyone confirm this?

I believe that 51531 was running with 51556 on July 31st so more shuffles of the pack?

Recent change then, I had 51530+51531 on July 26th

51530 is out with 51557 at the moment.
51531 which you saw with 530 is with 51532.

Thanks for the update, does that mean 51706+51556 are together?

Despite regular fairly regular travels on the Northern Line lately, I've not seen any more revised pairings. Has anyone else found any?
