Im gonna be the first to say it now Superalbs seems to have abandoned the class 700 project and taken his facebook page down. Dovetail come on and start working on it. More money in it for you as its 3 routes you have made that you could make scenarios for the class 700 (ECML- London to Brighton - Midland mainline) Would love to have it as a unique add on as its a train made for the beginning of a new era of rail travel.
With the new timetables the 700s also run Bedford to Rainham in Kent, so a tie in with the Chatham Mainline scenarios would be available. The current "networker" scenarios in the CML packs are no longer relevant, with the 700s replacing the networkers beyond Gravesend in may 2018
