Hi everybody.

Is there a way to find out if a route is good to make money? I think I've found it:

you have to see if the cost per km of your mean of transport is higher than the revenue of the goods it's carrying.

Example: a H-Trans Car transporter carries 16 cars. It costs 5,00 ¢ per km. 1 carried car's revenue is 1,27 ¢ per km (as seen in "all goods list"); so if you carry 16 cars your revenue is 1,27 ¢ *16 = 20,32 ¢ per km. So 20,32 ¢ per km (revenues) - 5,00 ¢ per km (cost) = 15,32 ¢ per km (pure earnings).

I use this method to find out if trucks are more profitable than trains in carrying the same type of good, or to find out what is the minimum profitable percentage of load that gives pure earnings. :

But I've seen that for cement transport it doesn't work, even if the calculation I do tells me that would be earnings: when I transport cement I'm always in loss. :-\

So I think my method isn't totally right and I ask you: what is the way Simutrans calculate costs and revenues of goods?

Sorry for my bad English :(
