Hardcode events

[zzc]

Most of them are pretty self explanatory;

freight car weight change
electric train and track
houses stop using coal and oil
tool n die stop using iron
weapon factory stop using lumber
munition factory starts using chemical
toy factory stop using lumber

but what do these do exactly;

automobile use
plane use

reduce passenger production?? price?? both??
does it affect mail too??

I have another question on troop behavior too.

Ah. Those reduce passenger production. The idea is to simulate when other forms of transport start stealing express traffic from railways.

As far as I know it doesn't affect mail. It's unlikely to affect price either, as prices for express cargoes are hard-coded into the .exe. They're different in this respect to all other cargoes, which have their prices set in a .cty file.
