Replying to I need some info on costs, stuff etc for a rail session

I wanna try to organise a rail session. But no one has ever organised this in my country (I live in Holland).

I'll probably organise it in one of the cities and i some ppl would really be interested in joining and even more in watching.

I know some ppl here have experience with organizing those things. So plz help me out with how to get a permit, snow, what kind of materials i could use best and what do you think is a sick setup.

Thanks!
