Yesterday, I was doing a bit of complaining about the new Tube map. I was specifically concerned with how to find out what zone a station was in now that zones have been removed from the Tube map. As I was getting on the Tube at Tooting Broadway this morning, I noticed the Fares poster pictured on the right. I've never noticed these before, but they do indeed tell you which zone each station is in, as you can see from this close-up. Given the state of the poster, I'm assuming it's been there for a while, but I'd just never noticed before.
These posters seem to be available in all stations. I've noticed them today at Tooting Bec and Kentish Town stations, futher demonstrating how unobervant I am.
The only problem is, they're nowhere near the Tube map. In some cases, the Fares posters aren't visible from the Tube map. Their placement -- close to the ticket machines -- makes a kind of sense. Nevertheless, this means that if I'm planning my journey at the station, I'll need to find a Tube map to figure out which lines I need to take and where to transfer, then find the Fares poster to determine what type of ticket to purchase. It's not ideal, but at least the information is available.
