 The main purpose of ATP is IMHO to get rid of the second man from the
cab. However it is forced on us even when, as in going west (young
man) ther are 2 men on board. When there are/is 2 men and the ATP
gives trouble (which is most of the time) we usually get authorized to
cut it out. Which is wot probably happened on your trip.
Interestingly though the Department want to introduce DOO operations
in train order (DTC) territory where ATP will merely record what has
happened on the trip. How they justify this will be interesting
reading :-)
