What did I see?

[Wilts Wanderer]

Last Friday lunchtime I was on a Eurostar departing Brussels-Midi and while we were traversing the 30kph flyover to the south/west of the station, I noticed in the sidings down below us a very striking, blue diesel locomotive. It reminded me very much of the classic DB locos that were used as the basis for the Class 42 and 43 Warship locos manufactured on licence in the UK in the 1950s. It had the large rounded bonnet, high slit-like windows and a very rounded cross section, not in any way angular.

Does anyone know what it was?

My guess is that it was a Class 55 locomotive, one that's been fitted with TVM430 to rescue trains on the high-speed lines:
