I think each vehicle is decked out for a different purpose. There are the working coaches containing all the technical wizardry, a coach as a 'boardroom' which contains a table, video screen and meeting facilites, a mess coach which has comfy chairs for the crew etc, and a bunk coach. the NMT is designed to be a home away from home, I had one of its drivers ride with me while he was road refreshing and he said he loves that train to bits.
If anyone finds a decent link to photos of the interior would they post it on here please?
