Thank you for your replies. I was actually just wishing to buy a 7 day season ticket. The ticket office is not allowed to sell this until 12pm the day before of use or 12pm the Friday before the Monday of use. This office being South West Trains at Guildford. Only monthly or longer can be sold up to 7 days in advance I was told.
However one is allowed to buy it online in advance of those stupid deadlines. One might say it's to stop people travelling in advance but given the post will turn up in advance, that seems silly.
So I thought, why not buy it online for a change and pick it up at the TVM but that's not allowed and there isn't any reason given as to why it's not offered. To be fair in that case I was using Southern's Web Site but I couldn't even pick it up from their ticket machines, if I wished to.
I wasn't aware about their being a separate season ticket database but I was aware that train companies don't currently share the online sales with their station offices. I guess that might be due to historical technology in use at the offices and that may only change if they can afford to upgrade the technology. Given the econmic climate, could they afford to do such a thing?
A central seaon ticket database would be a good idea. During the course of one week I currently pass through stations with 5 different companies ticket offices and on an average day it's always 4. Tickets are valid for multiple companies, so it would make sense to share the data. I might understand if they were restricted to just the trains of the company who sold the ticket.
