I've been looking around to see which railways have posted their traffic figures for 2013. The cynic in me thinks that those with good figures tend to publicise them better and quicker. So far I haven't seen any, so would be interested to hear of any people have seen. For the larger railways, there is probably a natural maximum (ie WSR is around 200,000 a year), on which they are able to base their business model around. For others, maybe they hope to have increasing numbers to justify further development, but how realistic is this. The market for travel on preserved railways appears fairly well developed.
