They won't shoehorn it onto the existing map, or print out separate cards.

My intuition tells me they'll do a glossy 3-way folded leaflet explaining the service (like what they do for bikes and boats) and the map [tweaked] will appear in that.

If they do put up poster-sized maps, they can use the space in the stations where the ticket office used to be...
"Bus shelters on nightbus routes usually feature a normal bus map and then a second poster showing just what runs at night". In my experience, the night bus map is often more prominent than the day one, much to the confusion of tourists (and sometimes to me)...

SE London once again getting a raw deal from TFL services...
My son needed to catch a night bus for the first time last weekend. It took 2;5 hours for him to get from the centre of town to Harrow! Doesn't look like it'll be any easier one night trains begin either!
Why the big void in the north-west corner? Really surprised the Met line isn't one included.
@Cornish Cockney
None of the "sub-surface" lines have been included (nor has the Bakerloo or the Drain). This does indeed leave a hole in NW London. I understand there are practical reasons for the selection of the lines to have night services - the Bakerloo presumably because TfL doesn't own the track north of Queens Park, but according to the article on London Reconnections
http://www.londonreconnections.com/2013/big-changes-gonna-come-part-1-night-tube/ the SSL will follow when upgrade work is completed

@anon 0901
On the contrary: only three of the eleven Underground stations with SE postcodes are not served by the night service!

You could design a special night tube map, but why bother - apart from the typeface this map is perfectly clear, and anyone familair with the shape of the day map will quickly recognise, for instance, which parts of the Central Line have been favoured (clue - no stations outside Greater London are served)
CornishCockney - the subsurface lines will be added once the current upgrade has been completed; as ever London Reconnection has more detail.

Perhaps the Night Tube Map will be branded with the "grumpy night owl" now reappearing on the new style of some night bus timetables? These have reintroduced the old style of bus timetable for those night routes that run on a lower frequency (e.g. every 30 mins).

Surely the Overground map is simpler because it has abandoned giving any indication of service patterns, perhaps to avoid information overload in a map already cluttered with tiny symbols.
DG's brought up a point I hadn't thought of - hotel operators near Heathrow won't be happy now it's possible to depart your house at 3am and arrive for a morning flight, especially Sunday morning.
@ Roehamster - to be fair the tube map does not show service patterns either. There's nothing to show how complex lines like the District, Piccadilly and Met actually work. I would argue it is simply not feasible to create such a map without it having dire consequences for clarity.

I suspect that the night tube service pattern will be simple with the small exception of the Northern where the northbound service splits at Camden.
Just to be explicitly, crystal clear:

there is absolutely no link or dependency between the ticket office closure plan and night tube.

This was pure spin from TfL at the time of the launch of Night Tube to try and gain support for the closure plan.
OK, so given the challenge laid down by DG, I'm doing a all-new night tube map.

Looking at the original: why is Hammersmith changed to a blue tick when it's supposed to have "white" wheelchair access?
Current map has Kilburn as a tick, night tube map has Kilburn as "white disabled".
"There's nothing to show how complex lines like the District, Piccadilly and Met actually work."
The met has been split into four different colours (purple, yellow, orange and pink) in the last sixty years. The District could readily be rendered as two colours (with some doubt as to which of the two lines the Wimbledon-Tower Hill line would be shown), and the Northern will doubtless be given two colours when it is split.
Here's an attempt at a better Night Tube map - corrected most of the errors

http://ukfree.tv/styles/images/2014/night%20tube%20map.svg

I have made Mainline stations have a grey national rail mark, as they don't have overnight trains, with the exception of the Gatwick Express.

I've taken out the bends and clutter, as per DG's suggestion.

Comments welcome...
Kilburn lift currently out of service for several months, regular tube map has been updated to show this. (It has a dastardly red dagger to indicated that there is currently no step-free access!)

Night tube map was published (and not updated since it was just a preview) at the time when Kilburn's lift was in operations, hence the difference.
@Briantist

I like it.
you asked for comments, so I would suggest you could save some space by closing up the spaces between stations on both lines west of Stratford, to allow the stations east of Stratford a bit more space - (this might mean running the Vic Line at 45 degeress all the way to walthmstow.

You could also straighten out the western end of the river, and perhaps the far east of the Central Line. the latter could be a straight line at 45 degrees all the way from Liverpool Street.
Timbo and others - I assume the Bakerloo is not part of 'night tube' because it is too old and unreliable and they need to Friday and Saturday nights for maintenance. No idea, though, why the City branch of the Northern Line is not included as I thought the trendy areas around Old Street and Angel would generate enough traffic.
@8:36 Thanks for the comments.

I have made a second version which has had a further round of simplification.

http://ukfree.tv/styles/images/2014/night%20tube%20map%20v2.svg

I have removed the 45 degree lines from the Central Line totally, and from the Heathrow section of the Piccadilly Line.

The Stanmore to Bond Street section is now JUST a 45 degree line.

The Northern Line runs just north-sound.

Harry Beck would be proud!!!
getting close to harry beck's original in fact. He chose strong colours for the Northern and Central precisely because they formed x and y co-ordinates.

You could make better use of the empty space in the bottom left corner by running the Piccy in a straight line diagonally from Green Park to Heathrow (and straighten out the river as well)

Picadilly Circus is shown as an interchange.
Have TfL said why no DLR or LO services are 24 hour?

The East london Line LO is surely tailer made as it serves so many busy late night spots.

The DLR would also help SE London which is still reliant on awful, slow, infrequent buses. 2-3 hours to get home is not uncommon from Camden to Bexley/Greenwich/Bromley boroughs. I suppose you can now go N Greenwich and enjoy a long and slow bus from there. Plus as canary Wharf continues to grow and more late night/early morning staff work there and night spots open the DLR link to it being 24 hr would be a great benefit.
Maybe this will make a completely new tube challenge!
@10.05.14 - updates in line with your suggestions http://ukfree.tv/styles/images/2014/night%20tube%20map%20v2.svg
The originally unveiled Night Tube map seems rather too similar in design coherence to my hastily made, semi-tongue-in-cheek 'tube strike solidarity' rail map:

https://db.tt/kvWmDdX0 (PDF)

I literally just deleted out everything Undergroundy from that map (and did a few subtle tweaks like changing the boundary station in the key to one I hadn't deleted!), and as you say that's really what that Night Tube map looked like had been done - perhaps because the decision to announce it was rushed forward for spin purposes when announcing ticket office closures?

I wouldn't be surprised if, nearer the time, we got something more like Briantist's effort - I'd guess more like v1 than v2, but who knows?
Rather than add a symbol to every station on every night tube line, there just needs to be a (crescent moon) symbol next to the line name in the key.
