I am quite attached to this line as it is my local route, the Class 378 EMU holds a special place in my heart and I would love to see it in the game, the Class 710 could make an appearance at Gospel Oak and the Class 378 could appear on the Gospel Oak - Barking add on. It would also be a nice addition to have both old and new Class 378 liveries.
It would be a great route which is driven in manual. A lot of stations and variation and a new London Terminal Stratford would be included. Brilliant suggestion and it would compliment the Suffragette line beautifully
