This is a semi-automatic signal An automatic signal is always green if there is no train

The Clue


Recap


Safety

If this signal (G3) fails, what does the driver do? Driver can proceed in accordance with rule book Points must be blocked Staff member on platform

A great deal of nuisance and delay Increased risk of runaway

Mitigation by standard solution Dual filament bulbs


Dual Filament Bulbs

Standard Railway Practice

On LT, normally only main filament is (was) lit

If main filament fails, second filament automatically switches on Lower light intensity Also warning light in signal box comes on Drivers should notice and report lower intensity


Early LT Telephones

1939 First direct dial LT telephones

1940 Dial “INF” for Central Information Desk (Leicester Square)

1948 Experimental Breakdown Message Recorder introduced - dial 48 (abandoned 1949)

1951 Information System Message Recorder introduced - dial 19


Modernisation

1962 Central Information Desk moves to 55 Broadway; “INF” connects to “Information System Assistant”, “19” still connects to recorded message.

1973 “INF” changes to All Figure Number (AFN) ”463”

1979 Information System Assistant number changes to ”908”


Programme Machines

1958 First Programme Machine Controlled Signals at Kennington

1965 “Electronic” Programme Machines Permitting greater complexity

1971 Golders Green Signal Box Closed; Signal G3 becomes Programme Machine Controlled Supervised from Northern Line Control Room,

Cobourg Street, Euston


The moral of this story...

What can we learn from this Use Case? There’s nothing new about the Internet of Things There is something different about the Internet of

Things Complexity is always a friend of failure Security is also a friend of failure The environment will change in ways you did not

anticipate What else ... ?
