On the return journey I want to leave London around 1430 and NFM 06 says that return travel is valid from Paddington or Waterloo between 1010 and 1501 or after 1900. WebTIS (Southern) will not let me select either the 1420 or 1450 departures from Waterloo.
The wording of the restriction in NFM 06 is
FROM LONDON
See Note A below
Note A
Valid on services departing London Paddington or London Waterloo between 1010 and 1501, or after 1900 (departing Reading, heading west (i.e. services passing through Didcot Parkway, Oxford or Newbury ONLY) between 1030 and 1530, or after 18900
This is very poorly written. When is
18900? To make sense, I suspect that should be
1800) or
1900). But how is a member of the public supposed to work out which?
EDIT - A friend with access to
The Manual tells me that
18900 is printed as
1900) in that document.
As written, the restriction states that
departing London Paddington or London Waterloo between 1010 and 1501, or after 1900 is the same thing as
departing Reading, heading west between 1030 and 1530, or after 18900. Even allowing for the typo in the last time, this is not the case at all. The 1420 and 1450 from Waterloo meet the Waterloo restriction but fail the Reading one.
Someone has coded the restrictions with an AND instead of an OR.
