For weeks we debated what new colour would be used for the line - we came to the conclusion that almost every colour had been used and that they would have to go with some sort of dotted line/alt line much like the overground. And we were right!
The new line is a double purple line to mark the new stations and joinings to old ones.
What do you think - do you think the Crossrail line colour is a good one or should they have gone for something else? A zig zag perhaps?
