Hello to all! How about T12 tank wagons? The new "BP" and "Bensol" models in today's Hornby presentation on YT are described as era 2/3, while the designation on the website www.hornby.com directly indicates era 4... British railways are still not fully known to me but the division into modeling eras on the continent is much more clear and consistent... Era 2/3 (potentially, therefore, era 2) and era 4 are a dramatic difference! the markings on the new models resemble earlier T12 tank models in TT (so era 2/3) but maybe I'm wrong? Can the red frame of a wagon for transporting hazardous substances be a determinant of era 4?
