It's very pretty. But what is the user benefit?
I can see how you benefit. I can see how an advertiser (might) benefit if they get clicks. But what is there here to make a user want to come to the site or ever come back? Therefore, ultimately, how will this work for the advertiser?
I'm not just having cheap shots here, I
am genuinely interested. Have you considered apending genuinely useful information to each station (such as nearby shops and tourist attractions, timetables, etc etc) and even then would it really be a pull.
I take your point about it being cheap. In actual fact, it isn't cheap unless it generates a lot of traffic/business. One click at £14.99 isn't cheap. It is inexpensive - not quite the same.
Product extension - The Virtual Kitchen - picture of a kitchen where every appliance and item is sponsored by a relevant supplier of those items etc etc. That might at least make sense of the context.
However, really lovely illustration work! Site looks pretty.
