What could be some stock I could incorporate into the Equestria Speedmaster?

[CaliforniaSpeedKing 17]

Equestria's Speedmaster is the high speed rail Equestria uses for it's nation in my AU, It uses Shinkansen 0, 100, 300 and E2 series trains alongside Britrail Class 395s, ICE 3 and 4s, Eurostar E300 trains and P700s (Equestrian made). What else could I add to make it even better?

 

Any work but secondhand is preferred. So... what do you suggest?
