For several queries related to train travel time tables, I have noticed special google SERPs. These show up as a little train image with an indented meta description next to them. They appear on top.
One of our clients has asked us to try and obtain such a listing, but frankly... We are completely baffled. The 'special' result showing now is from a company that is not relevant to our country and we have no idea what is causing them to show up like this.
