Long-time readers will be, no doubt, relieved to hear that my train down to London this morning was 390-054. Foolishly, I didn't look at the nameplate so I don't know what its name is, or even if it has a name. Wikipedia isn't helping here either. For extra memorability, it arrived in reverse configuration, that is with first class at the back of the train rather than the front, causing much harumphing and kerfuffle on the platform.
Bonus factoid: No wifi on this train. I thought at the time it just wasn't working, but apparently the Dept for Transport wouldn't allow it to be fitted. I wonder why.
