The connection to science isn’t explicit, but there’s definitely an implicit connection. There’s the engineering it would take to design efficient rail systems and modern locomotives, there’s the calculation of relative emissions cost compared to reliance on automobiles, and all the science on the impacts of those emissions, the calculated benefit of converting infrastructure to rail-based, etc.
It doesn’t out and say it, but anyone with the basic knowledge should be able to draw the connection.






It’s not equal to engineering, but it’s certainly involved in it.
That’s like saying x ≠ x²+3x+b
Of course it’s not equal to it (unless x and b both equal zero)
