I am not very good at maths but had a go at working out if the train is worth the money. I bought the Long Bulkhead carriage for the metals.
My workings are this:
Copper sheet for 3
50 x 3.5555 (copper ore per unit) = 177.77775
1512 delivered by train divided by 3 = 504
504 x 177.77775 = 89599.986
Aluminium sheet for 5
100 x 14.4 (aluminium ore per unit) = 1440
2520 delivered by train divided by 5 = 504
504 x 1440 = 725760.00
Steel sheet for 5
89 x 1.9323 (iron ore per unit) = 171.98
11 x 26.666 (chromium ore per unit) = 293.333
Both = 465.00
2520 delivered by train divided by 5 = 504
504 x 465.00 = 390600

total cost of materials = 1,049,328
Cost to despatch train = 3,402,000

Is my maths incorrect or are we paying over the odds?
