The London Transport 1938 Tube stock (and probably earlier) had an array of 
five white lights on the right side below the motormen's cab.  Depending on 
which lights were lit, could indicate vertical line, horizontal line, or two 
diagonal lines.  This was particularly useful for indicating to signalmen on 
the Northern Line if the northbound train at Kennington was via City or 
Waterloo, and in both directions at Camden Town.

The letter "D" is to indicate how the mu coupling is set up at this end of 
the car.  In years past, LT tended to be very restrictive as to where a 
particular type of car could be marshalled in a train.

Suspect this light array also on the sub-surface stock from this era.  The 
District and Circle services are/were somewhat complicated.

There's no way I can get this back on topic.  How about using a 42/38 PCC 
car to travel to a travel agent in downtown to purchase my airline ticket in 
1969 to travel to London to observe these trains???   <gg>  (how's that, 
Derrick??)
