Did anyone run Trix stuff in the early 60s? I still have a die cast Britannia that could haul 14 HD tin plate sided Mk1s without effort. Ok it was HO not OO but as a working model it was superb for its time and outperformed my HD Castle. And to my eyes it was the most accurate model of a Britannia in terms of cab shape etc. for nearly 50 years until the most recent Hornby iterations. I also bought a number of the Trix plastic self-assembly Mk1s (again made to HO scale) which included a BCK, unavailable from any other manufacturer, and commonwealth bogies. They were easy to cut’n’shut to make other types unavailable at the time such as an SK. Given that everything RTR then was not 100% accurate in terms of scale, size or dimensions, the difference between Trix HO and the OO of the rest was easily overlooked.
