Yesterday I viewed all the off peak pairs (and a few inter peak stablers) of D stock in my quest to get my last four required sets for haulage. I got three out of four so it was worth a lot of standing in the cold! Train numbers and formations shown below with the odd numbered set always at the Upminster end of the train. Note that some sets swapped around at lunch time. I didn't see train 20 until 1400 by which time the sets off train 47 had swapped on to it.

Apart from the 83 stock, the D stock are the first trains I can remember from when they were new. Seems odd that they will start to be withdrawn in a few months.

Are the D stock made up of 2 3 car units back to back? And what is the number scheme used on the D stock?

Yes, the D stock are 2 3 car units coupled together. There are also some double ended units which can be coupled up to normal single ended cars. This page explains it well |

The linked page explains it comprehensively, but briefly:
Single ended units are formed DM-T-NDM , Double ended units are formed DM-T-DM
DMs are numbered 7xxx, NDMs 8xxx, Trailers 17xxx
In normal use, a six car train is formed by two single-ended units back to back, or with a single ended unit coupled to a double ended unit. (two double ended units are slightly too long to opreate in passenger service and, because of the two empty cabs, have slightly less passenger space.
Numbering:
A (west) end units:
7xxx-17xxx-8xxx where xxx is between 000 and 128 (even numbers)
D (east) end units
7xxx-17xxx-8xxx where xxx is between 001 and 129 (odd numbers)
double ended units
75xx-175xx-75xy where xx is an even number between 00 and 38 and xy is the next odd number (e.g 7538-17538-7539)

I will be sad to see these unit go as they have distinctive character and i think the last overhaul/upgrade was a job well done

I spent some of yesterday evening peak (22/01/14) on the District looking for my last 4 units. Recorded all of the ones seen (almost all in service) and their train numbers as follows:

123: 7118 + 7099
124: Not seen
125: Not seen
126: 7053 + 7509
I did also notice 7000+7531 heading East but didn't see the train number, and also 7034 on the back of a train heading East, so that's 2 of the 9 not seen.
Managed to see 3 of the 4 units wanted, still not seen 7076.

Silly question time while on the subject of formations, and the above lists.
I bet this has been asked before but its not coming up in a search for me.
Can you run in normal service a D stock trains formed of two double ended units ?
I'm not sure why anyone would actually want to do that operationally, but technically can it be done, that is without mods, by simply coupling two together ? Or can't you couple DM to DM ?

Two double-ended units can run together as a 6-car train although they are longer than single-ended units and could overhang the platform end barriers, their use has been discouraged for some time.
DM-T-DM+DM-T-DM 109726mm
DM-T-UNDM+DM-T-DM 109473mm -253
DM-T-UNDM+UNDM-T-DM 109220mm -506
When introduced all trains were formed this way as the double-end units were delivered first.
Empty movements to the ELL were also 6-car double-end units.
