deanparkr,
Firstly, I can only apologise for the foul-mouthed and disgusting attitude just displayed by 'class313' and 'D306'.
In answer to your question, South West Trains has a policy on the conveying of cycles on it's services, referring only to non-foldable bikes. Folding bicycles are exempt from the restrictions and can be stowed as luggage. If you are planning to travel on a 'West of England' service (London Wateroo to Salisbury / Yeovil / Exeter and beyond) then you must obtain a reservation at least 24 hours in advance.
If travelling on any other service then it may be worth going about obtaining one anyway, but you are not required to do so. That said, you will be unable to carry your bike on the train if all dedicated cycle spaces are already taken. Said reservations are free and can be obtained by phoning the Customer Service Centre on 0845 6000 650.
There are no restrictions on services travelling between Ascot and Guildford via Aldershot in either direction at any time of the day.
The white Class 444s have dedicated, bike-only space for six cycles per five carriage unit (spread over two coaches), where as the four carriage blue Class 450s have just two. In the case of the latter, the fold down seating area is permitted for use by cycles (in addition to the dedicated storage area) if unoccupied by seated passengers. When I have travelled in this area of the train, I have observed a black/yellow Tensabarrier that can be used by the cycle's owner to cordon this area off.
There are time restrictions on when cycles may be conveyed. Cycles may NOT be carried on South West Trains' services:-
1) Arriving into London Waterloo between 07:15 and 10:00 inclusive, or departing from London Waterloo between 16:45 and 19:00 inclusive. These restrictions apply if travelling from or to stations within the area bounded by Alton, Dorking, Guildford, Hook and Reading.
2) In the morning peak when travelling out of London Waterloo to any station as far out as, and including, Feltham or Strawberry Hill.
3) On services departing from Clapham Junction between the hours of 07:45 and 09:00.
4) At any time if travelling on a Megatrain ticket.
Hope that helps
