Does anyone know how the Jet Lag crew manages their seeking maps?

I'm currently planning logistics for a Jet Lag game in my city and I'd like to get physical maps to help seekers mark off where they know the hider is not. But I'm curious about what their maps are like. Does it show all legal stations and lines? Only the biggest trunks? Does it also show the various administrative regions? Do they show streets and waterways?

Also, what size and material are the maps?

Has anyone watched the Hide & Seek seasons closely enough to know the answers to any of these questions? Or does anyone have their own ideas from personal experience or just thinking about it, for running a home game?
