How to find free advertisement?

[Stuart Mccabe]

Of late I have become more actively involved in the local railway heritage that takes place in the town next to me.

We're making pretty good money at the moment, but part of the railway's means of getting money is to have people come and ride on it, and to do that, we need to advertise a bit more. The only form of advertisement I know we do is, other than word of mouth, is Facebook, but what other ways can I advertise the railway?
