I used to work in Battersea and loved going 'the wrong way' to work in the morning, getting a seat every time and a commute of about 30 minutes train to door, plus the zone 3 bit was great too. But I think the destinations are all up for grabs.
Just another note on the maintenance issue, these murals last about 20+ years in good condition and still look good many many decades into the future (we've worked on a few of public art projects and with signwriters/mural artists now) and and when they do peel a little, they age with dignity and actually look rather good. In another area we have used some of the posters Hannah posted above (which I think are beautiful) as public art, which is being recreated by a mural artist in Northwood Hills. We also used it on local branding, murals and bags for life (the area originated as Metroland so we updated Metroland tube posters). It's gone down really well. The sign for Sydenham is actually based on bits of some of the posters from the era of the building in Station Approach that we saw in the recent poster exhibition in the London Transport Museum (it made sense when combined with the branding for On The Hoof).
The main issue I think is about the times, making them a little free'r, say 'London bridge in under 19 minutes' makes more sense. Anyway, there are a few things to address. Keep the comments coming.
Oh, and Steve, lightboxes can look good in the right circumstances, context and design (we have done a few in our time), but I agree, this building isn't one of them.
Be patient on the updates though, we have a mountain of stuff over the next few weeks coming up!
