I've recently started a new route. I will not submit is as part of the challenge. I hope it is interesting all the same.
I've marked out the MML, between London and Bedford. I've got the line marked out between the tunnel at Elstree and Borehamwood, beyond Bedford as the straight there needs to be dealt with. I've marked out the route, all lines up and down and slow lines as well. The resolution is warped, but a line of best fit will do.
I am interested in this challenge as I hope it will produce many fast route building tips.
I think I've got a few more days of marking to do though.
Good luck to all participants! It was too fast for me!
