Having looked at the last several polls (2014,2015, 2016 and 2018 is all I could find after doing a quick search), GWR 813 has done pretty well for herself at the polls. Having been in overhaul between 2010 and 2016, I find it no surprise that 813 would rank low as not many had heard of this unique 0-6-0 at this time. When she was Didcot last year, there were people there who didn't even realise that she was unique to her type. She also didn't have a massive multi media following which does help unique locos like 813 gain more attention further afield.
Since returning to traffic however in late 2016, she has managed to beat every other pre-grouping GWR loco. This even surprised me considering several of the other contenders outlasted 813 (withdrawn in 1933) and went on to serve in BR era and I'd of expected to be in higher demand. Her moving up in the polls is course down to her travelling far and wide once again, charming many railway enthusiasts and also visiting several new railways which she didn't visit in her previous boiler ticket.
Should GWR 813 be announced someday in RTR, I will very much welcome the GWR, NCB and various other industrial liveries 813 and her other sisters inherited.
Well done 813.
