I know this will be a network rail test train but does anyone know what type it'll be and what the traction could be? It heads to inverness the next day then back to derby via the HML, Fife and the ECML.

Guessing from the timing load, it appears to be loco plus DVT, or loco at either end. From what I remember the NMT is timed as an HST in TRUST, so I am reasonably sure it is not that...
Unfortunately I am not at work to check...
