Having seen the Yellow Network Rail HST New measurement Train in a few screenshots and threads, I was wondering if someone could tell me what this train actually does?.
I saw it for the first time today passing through my home town heading Eastbound at about 5pm and I thought I would ask, as I'm sure someone on this forum will know.
Thanks
