Ok. I understand the logic in "real life" but isn't it counterproductive in terme of game balance? I mean a loc with a bad power/weight ratio is already less interesting because they have less excess power. It seems to me that if they also cost more they become almost useless in term of gameplay (as they would irl actually ;)).
I will try to translate the formula as i don't understand it in german to see if i can think about something that may help you with multiple units.
Hello again,
Sorry for the double post but as the previous one is 9 hours old i prefer to do a new one.
I have been thinking a bit about it, and i'm pretty sure that removing the weight from the equation would solve your problem with EMU. Most recent EMU have multiple powered boggies instead of all the power on the loc. Which mean that the price will skyrocket because the "power/weight" ratio will always be bad as the weight of the whole train will be taken into account. Anyway i don't think the engine on a lighter loc will be less working than on an heavy loc, because the extra available power on the former will probably be used to add more weight on tow.
On the other hand it may be interesting to take into account the availability date. It seems to me that modern trains tend to not necessarily be more powerfull but to be more cost effective. It probably should not be linear but the maintenance price by kw should start to slowly decrease around the 90s or 2000 (totally made up numbers :)). It would then be an incentive for players to replace a 6400kw Eurosprinter by a 6400 kw Vectron made 10 years later, for example.
I can also translate the description in French if it's not already done and you want to add other languages to your mod.
