I have found it interesting about the designation plate on the trains
and recall during my formative years (30+years ago) of being able to use
the plates as an id - hey remember when the lights indicated the
destination, left top, right top and middle for east hills.
Anyway my next question is to do with carriage numbering,
Dxxxx = car with driver cabin & pantograpgh
Txxxx = car defined as trailer
Cxxxx = car with driver cabin - no pantagrapgh
put on O infront for outer surburban Tangaras
yet this morning at Waverton I thought I saw a car with a Dnumber but no
pantagraph
and now as I look out the window on Central, there is a tailer car with
N, this on a standard Tangara
Many Thanks
