3 3/4 cars = 3.75x32 Studs (couplings included) = 5 triangles = 120 Studs
That means each triangle is 24 studs long...

the 2.5 are estimated and the 50 studs are in fact more than 60...

Each yellow part is 96 cm as demonstrated above: 5.15 minus 2x0.96 =?3,23 m?
That is impossible. So the 5.15 cannot include both yellow bridges, or the bow
would become very small....

It is in fact 5.15, wich can be recognised if you count the monorail track
pieces: there are 20 sections of monorail: each is 32 studs long. Makes 640
studs total length which is 5.12 meters.

You really bluffed me for a few days. I was not too sure about the real length,
till a friend of mine told about the length of the monorail track pieces (a
part which I never owned).
Kind regards,
Ben
