There had been news that WHSmith is selling 2019 diaries with Tube maps in the back, and that these Tube maps have the Elizabeth line on them. Since I couldn't find any pictures of the Tube maps, I nipped into the Holborn WHSmith and picked one up myself. For those interested, here are pictures of the Tube map, which the diary insists is "Correct at time of going to print."
I don't think the map differs much from the draft December 2018 which had been shown previously. But when the "official" map comes out on the opening of Crossrail, it will presumably have zones, step-free icons and dotted OSI interchanges - including an OSI between Woolwich and Woolwich Arsenal?
Given typical production deadlines for bound diaries it seems WH Smith will have been supplied presumably by someone at TFL with that map quite a while before the opening delay was announced.
Of interest it seems to show an intermediate arrangement of services, with the Elizabeth line effectively depicted in three separate sections with services west of Paddington being shown as only interchange with the core section and a similar but separate interchange for services to the east at Liverpool Street.
One upside of the delay is that WH Smith can probably re-use this map in their 2020 diary as it will probably be reasonably correct then.
The original plan was that the Reading branch wouldn't open until December 2019, as a full through service to Abbey Wood. This map reflects what the situation was meant to be in December 2018, with the Heathrow-Paddington, Paddington-Abbey Wood and Liverpool Street-Shenfield sections open (and branded as Elizabeth line) but disconnected.
Now that Crossrail has been delayed, this is up in the air a little bit - but since the Reading to Paddington services are financially lucrative for TfL, they are keen that they still take over the Reading to Paddington services on the original planned date of December 2019.
This might mean that (if the core section opens in December 2019, but through services don't run) the Reading service is shown on the Tube map joined up with the Heathrow line but not with the core line (i.e. there's still a break at Paddington). Alternatively this might mean that (if the core section isn't open in December 2019), Reading to Paddington services become branded as TfL Rail and join the Tube map in December 2019 along with the Shenfield and Heathrow services (but not the core section).
If either of these two outcomes happen, this map will end up looking particularly odd: it would not accurately represent the status of the Elizabeth line at any stage in its history!
