Forgive me if this may have been answered already but it's been something i've been curious about :3. Since i will be commuting a lot on this line To and from college (glasgow) and i like to trainwatch on this line too, I've been wondering. I've heard a lot of talk about how the AT200 trains will replace the turbostar/class 170 trains around 2017-2018, but i've also heard that the 170's maybe will be replaced by the class 380's too, so will we have a sort of mix of AT200's and 380's on the line in the future or maybe just AT200's or a mix of AT200's 380's 334's and maybe the odd 322?. I'd like a mix myself , i'm just going to be sad when the 158's are gone, I tend to find them more pleasant than the 170's. also im wondering if i might see more 92's 91's and 90's working the freight, east coast and sleeper's? again sorry if this is very "noobish" to ask :3, It's just been a curious question in my head.
