Cool Sharadise, the 465 is a welcome addition, still remember the struggle with a.light ;-)
Check out the route <kuid2:582486:101273:3> DSEPR03 HS1 London to Lille V6
made by anatoth71, many miles of 3rd rail track on there, often besides the HS1
Here I made a version with catenary on the HS1 from London-Lille
Would be nice if your new route would connect to it somehow.
If you need anything custom made, you know how to reach me
greetings GM
