When the terminus was Charing Cross

No.

I can't quote many examples as 'Big Bird'[1] is asleep in the LU Operations library - however I've got a 'pending' pile of Working Timetables to be shelved, after they have been catalogued:

I can find Jubilee 5 (3/11/86) on the sofa - there is no inverted delta symbol in the WTT, this has been used since the early 50s for 'stepping back' (Met. crews at Barking ISTR, but sleepers preclude further checking).

From memory, there was some form of 'stepping back' in about 1980/81 (in the first couple of years of the Jubilee, before Room 217 learnt the quirks ) Will report when I return from Acton as I've got a decent spread of pre-JLE [2] WTTs.

[2] Jubilee Line Extension

I managed a quick peek in the LU library before leaving Wales this morning and there was certainly some stepping back in WTT 1 (1979) - quite a few in the morning peak and about 10 trains in the evening peak.

As the Jubilee ran 20tph to Charing X, then there couldn't have been more than 4 mins to change ends.

Sorry to go off the subject here a little but I dont suppose any has any images of Charing Cross Jubilee do they? cheers

remember when i done my sa training we went down into the old charing cross platforms was really really weird lol and quite freaky as you can here trains rumbling and was very eary still a great experiance tho prob the only time i would ever get to go down the escalators to the platforms

It's a wonderful place and not creepy at all, I used to do the Jubilee point and signal maintenance there after it closed to passenger traffic but of course I worked all over the site from 1979 onwards and have been in most of the many nooks and crannies in the old Strand and Trafalgar Square areas as well as the Jubilee stage 1 site. Some of the more interesting parts of the site will never be seen by passengers or enthusiasts including the sidings and of course the cavernous inverts beneath the platforms, concourse and escalator chambers which in their day were quite a departure from the then existing standards which necessitated (and still does at most tube stations) working in very confined spaces at most sites.

In 1981 I had an office of sorts in one of the disused Trafalgar Square lift shafts and I was based on the station for many weeks installing new comms equipment and cabling so I got to explore a great deal of the site as I investigated the cable routes between the three lines.
