...Instead of "go to jail" it could be...."Go to the toilets"
You could have a "Get out of the toilets free" card etc....just for when needed!!!
The stations would have to be Wallgate, North Western, Ince and Crewe possibly?
Electricity company / Water Works could be "Spencers Bags" and "Russ Monster imports" etc.... who'se going to get the copyright?
