I like the big-wheeled tank.......have you noted the Highland Railway's 'scrap' tank, photo in link below? That has [had] a similar look, albeit a side-tanker....

G'mornin' all...thunderstorms yesterday PM...got home just in time to find dry washing now soaking wet......managed to unplug computer just as storm went away......since I followed it all the way home from work, just knew it would get here faster than me.....d'oh!
whilst on the subject of large single[?] units....[i have a wreck of the old old old B/mann DD40....] a local [?] model shop has a used Athearn DD[35] in EMD demo colours....[around 40 quids I think?]
now there's a loco to send the neighbourhood lights to 'dim?'
sadly I have a lot of UP stuff as well...not modern...mostly what was around in the '60's and 70's....
