Picked up some prepaid tickets today from the machine at Ashley Down Station which just happened to be shortly after the Bristol Rovers match finished. Although I couldn't see how many people had got on to the northbound service which pulled out as I arrived, there was still a steady stream of people arriving for both platforms including the Worcester Foregate service which pulled in two or three minutes behind the one that I just missed. Looks like a fair few services in each direction were stopping there in the hour after the match and people were catching on to this.
Not sure what the home/away fan ratio was but the numbers seemed encouraging.
It's a fair old schlep from Ashley Down to Lincoln. Respect to any Lincoln fans travelling by train, it isn't cheap or easy.
