Hi, thanks for editing in the information based on the CGI model. I'm a long time proponent of that being the actual scale. Altho, I must admit, I always got more around 55m meters in length, would you be so kind and share the math with me? I fully admit that my math sucks, so I've probably made some errors. Thanks!
I've also made some calculations, based on the width of the railways: here
I also wonder what could you make about this schematic of Big Alice. I've spoken with Alex and he will release an HD version of this schematic soon.
