Found in my attic

My 1985 map shows 299 daytime routes, 10 lettered routes (like E1) and an enlarged Night Bus network of 34 routes, most still oddly numbered so, for example, daytime route 89 (Lewisham-Bexleyheath) and night route N89 (Liverpool St. St./Trafalgar Square-Southall/Uxbridge) were totally different routes.
As a youngster (19/20) I would take the N89 most nights from Southall to Tottenham Court Road and then walk to Kings Cross Station to visit my Nigerian girl working in the all night Railbar.

There is a 1959 tube map HERE..... Not the same as having in in your hand I'm afraid.

There were two 1959 dated UndergrounD maps:
359 582Z/500,000
859/2100Z/500,000

The only difference being the printing on the Index side of the red dots to show car parks.

The previous 858 map was the last to show the South Acton shuttle.

Here is 859:

Russell Square, not Farringdon Square

ARSENAL HIGHBURY HILL too

Gillespie Road to Arsenal in the 30's as proposed by one of the finest managers in the history of football, Sir Herbert Chapman.

It changed to Arsenal (Highbury Hill) and latterly the bracketed bit was dropped, though I'm not entirely sure who was behind that.

Arsenal FC fully funded the changes to the tube maps, in-car diagrams etc when it changed from Gillespie Road, and I think it knocked them back something like £30,000 at the time.

Now there were plans to build a new tube station under Ashburton Grove and either replace Arsenal tube, or compliment it, but Finsbury Park took all the cash, and money was needed at Holloway Road as well.

As it stands, Arsenal tube will remain named that way forever, and there will be no further developments in that area.

The Picc more or less runs underneath Ashburton Grove, and in reality with Arsenal almost clearing the debt from moving grounds, a new station is possible as they would almost fully fund it, but planning permission will for now be totally against it.

As for Arsenal tube itself, there are hundreds of thousands of people against the idea of any name change or shutting the station down, even though it's fairly much only ever used on match days.

A night route along the 20 corridor would be very welcome by pretty much all of the Loughton and Debden residents I know. Even if it didn't go through Debden estate, a service along Rectory Lane would be good.
However, there is the small matter of night buses not leaving Greater London to overcome first.
