Surely such powerful locos would be well suited to freight operations in the future? That's what happened to the 86s after all. Grand Union Trains' website still seems to mention using them between Cardiff and Paddington (at least initially) which I'm praying with all my heart to be true. I'd never touch a GWR 800/802 again if it actually happened! Outside of open access operations, long term they'll unfortunately either be scrapped, or sent to Europe. At best they'll work freight trains and have a similar lifespan to the 86s.
