[CW] WW2 Use of V instead of DE

[pa0wv]

The answer is quite simple I suppose so:

It has no relation to railway code.

DE is French language and VON is german language for the same word,

So the Germans were for language purity, telephone or German Telefon was 
prohibited, because it was imported foreign language,  and changed to 
Fernsprechapparat (English  translated : 
device_to_speak_over_a_large_distance,  in German written without spaces 
as one word)

Because VON is much longer in Morse code compared with DE, hence not 
better, it was shorted to V
