Bakerloo are 200 to somewhere in the 240s.
The numbers sometimes relate to the stabling arrangements, for example
Bakerloo 241 is the London Road midday stabler.

221-227 Queen's Park depot starters
231-242 London Road depot starters
245-247 Elephant sidings starters

From memory, the emergency timetable is in the 0XX series, certainly for
Elephant to Queen's Park. I don't know what happens for the Harrow

Northern Special service (usually referred to as an "emergency
timetable" is usually numbered according to what depot is crewing the
train:
Morden: 300+
Golders Green: 350+
East Finchley: 400+
This can vary, depending on the service that is in operation.
Because a depot tends to work over only one section of a line during
special working, it usually means that, for example, Morden could be
running all the Morden-Edgware via Bank trains in which case all Morden
via Bank trains would be 300+. East Finchley could be running all the High
Barnet-Kennington via CX trains, so these would be 400+ etc.

There are different levels of special service, depending on where running
is restricted to etc.

) gurgled happily, sounding much like they
were saying :

Binary Coded Decimal is used a lot
with the programme machines and the various remote control of the IMRs
etc. and describers.

In BCD the decimal number is represented by the digits 0 and 1. The
number 4 is represented by 100, 5-101, 6-110, 7-111, 8-1000, 16-10000

Umm, not quite.

In normal Binary, 16 is 10000, but in BCD each decimal digit is coded
separately in four-bit Binary, so 16 would be 0001 0110 - which is why it's
called Binary Coded Decimal.

Note - I have no idea about whether BCD or normal Binary was used...

Sorry, my mistake. I forgot about that. I'll have to look at the programme
machine roll and check what is used - I think it just uses plain binary.

The circle and H&C have a shared number series, I think.
The picc numbers were in the following series (in 1999):

261 - 267, 270 - 272 Cockfosters to Uxbridge
273 Spare at Acton Town (midday)

347 Acton Town Overnight stabler
351 - 357, 360 - 366 Arnos Grove to Northfields
371 - 373 Cockfosters Midday Stablers

Is there a reason why the don't use numbers ending in 8 or 9?

I think this started on the Northern Line, with the introduction of
programme machine working in the 1950s, and other lines followed suit. On
the programme machine rolls, the information for that train is stored in a
row of punched holes. Binary Coded Decimal is used a lot with the
programme machines and the various remote control of the IMRs etc. and
describers.

In BCD the decimal number is represented by the digits 0 and 1. The number
4 is represented by 100, 5-101, 6-110, 7-111, 8-1000, 16-10000 and so on.
This means an extra wire etc. for each extra digit. I suspect that this is
the reason. I have the info. on it somewhere, but not to hand.

The dutys (on the Northern Line anyway) also do not use 8 or 9. I can't
remember when it changed. It was a long while ago, but mot at the same
time as the programme machine introduction.

Roger

The programme machines use octal numbering, which is why they don't
use 8s or 9s. It's also impossible to have a train number beginning
with a number higher than 3 on a programme machine signalled line.

A few train numbers you won't see:
375 - This is used as the "Start of service" by a programme machine.
376 - Used for "End of service"
377 - Indicates the programme machine roll has come off the carrier,
as all contact fingers are made.

Trains, as you know, are made up of carriages. Generally, these have a
bogie at each end, two axles on each bogie, and two wheels on each axle
- i.e. eight wheels in all. That is why they count in octal.

I stand corrected, thanks for the info.

Hmm, I've seen some pictures of Amersham trains (recent pics) with 401 and
402.......

Nope it has changed "recently"

Hi all

I am trying to find out which numbers go where.
So far I have this list, based on some lines:

Bakerloo: Possibly 2xx but not sure
Central: Don't know
Circle: 201-214?
District: 0xx (D-stock-trains) but what about the Wimbledon-Edgware
Road
services?

061-07? Wimbledon - Edgware Rd
151-152 (I think) Olympia- H St Ken.

East London: 171-176
Hammersmith & City: Don't know (unless it is 2xx above 214)
Jubilee: 3xx
Metropolitan: 4xx
Northern: 0xx
Piccadilly: 3xx
Victoria: 2xx
Waterloo & City: 201-204
Specials and engineering trains 7xx

How far "off-track" am I?
And can anyone expand the list?
For instance with service-specific numbers (ie. Olympia for District,
Uxbrigde/Ruislip/Rayners Lane for Piccadilly, Mill Hill East/High
Barnet/Edgware/City/Charing Cross for Northern and so on and so
forth...)

Thanks in advance!

Bakerloo are 200 to somewhere in the 240s.
The numbers sometimes relate to the stabling arrangements, for example
Bakerloo 241 is the London Road midday stabler.

273 Spare at Acton Town (midday)
274 - 277 Northfields Midday Stablers
300 - 307, 310 - 317, 320 - 327, 330 - 337, 340 - 343 Cockfosters to
Heathrow
347 Acton Town Overnight stabler
351 - 357, 360 - 366 Arnos Grove to Northfields
371 - 373 Cockfosters Midday Stablers

When running an emergency timetable the picc runs Cockfosters to
Heathrow (400 series) and Acton to Rayners Lane (500 series). The vic
emergency numbering is in the 000s, and I think the district emergency
series is in the 300s.
I can't help with the others; I've never seen the bakerloo run an
emergency timetable and don't remember the central's series.

Presumably when they increased the frequency of the Fast Amersham service?
