While it is exceedingly rare for me to advocate for anything other than an Australian route (you sent us here, you could at least give us a route lol), as an Australian supporter of the mighty Stevenage Football Club I'd love to see Kings Cross - Peterborough route. It would be similar to MSB with the main line service between Kings Cross to Peterborough with the 387 (plus you'd hope they'd also use the 365), plus the Hertford loop line between Stevenage and Alexandra Palace to with the 717 I imagine they'd use Hornsey depot, which has the class 08 Given Dovetail's love affair with recycling trains (which i don't mind), they'll have the 387 and the Class 08, plus I can't imagine it's hard to modify the 465 into a 365. The only new train they'd need is the 717. Comprises 35 stations between the Peterborough - London line plus the Hertford Loop, a good mix of all stops, semi express and full express, 3 different trains. I know Peterborough has at least two roads dedicated to freight, plus I think Hertford loop has freight
