Hi Chris,

a change like that wont be possible with the xml-configuration alone i 
am sure :)

the code you are looking for is the heart of rails besides the graphic 
engine. Its the network and revenue calculation magic being created by 
Stefan Frey which you can find in the rails/algorithms subdirectory. The 
both classes you should have a look at are RevenueDynamicModifier and 
RevenueStaticModifier.

Imho you will need to create a RevenueDynamicModifier_1861 which should 
do the following. Set the Reach of a particular Train to a sufficient 
large number to count all stops and cities on a route, determine the 
number of cities and only add towns to the revenue if the maximum of 
cities couldnt be reached.

I am unsure if there is an Expresstrain Implemented already but that 
would/should use the same mechanismn with a modifier...

Hope that helps

Martin
