Short train--what's it towing?

Nasty stuff, is what it's towing! The wagons are what is designated FNA - Flask Nuclear Air braked. The containers carry nuclear fuel to and from the British Nuclear Fuels reprocessing plant at Sellafield - whose tower can be seen in the background - and the various nuclear power stations in the UK. It's a legal requirement that these trains have two locos providing the motive power, in case of failure of one engine; Nobody wants a failed train of radioactive gunk sat near their doorstep!

Wow. Thanks for the explanation!

Well, not a simple image of a train is it. I think your treatment of the image is spot on for this.

Thanks!
