I can guess the answers but can some ticket expert confirm please ...
Available after 09:00 (Mondays-Fridays) or when Off-Peak Day Return is valid (whichever is earlier). Additionally valid on the 08:26 Westbury to Penzance service.
Available all day Saturdays, Sundays and Bank Holidays.
Not available on bus or ferry links or any other rail routes not shown on the map.
a) There is no 08:26 Westbury to Penzance service but there IS an 08:20 Westbury to Paignton, on which off peak [period] returns to places like Tiverton are valid but I can's find any off peak
day returns valid on it. Would an
FOSS▸ /
FOSW▸ be accepted on this train?
b) As FOSS and FOSW are "not available on bus", does this mean that the tickets are not accepted on buses that are run to replace trains?
c) The accompanying map shows only the FOSS (not the FOSW) valid from Romsey to Eastleigh via Chandlers Ford and from Brockenhurst to Lymington, and only the FOSW (not the FOSS) valid from Bristol Parkway direct to Newport.
As the quote and map are from the official National Rail web site, is it fair to assume these exclusions?
