                            Concept : Train Types

 Trains provide a convenient means of transporting large quantities  of  goods
across  land.  The difference between using trains (or other vehicles) and the
move and transport commands is that trains can be moved across  foreign  soil.
Trains  are  therefore a land alternative to using ships, for example, to move
goods in a game that uses trade center markets.

The train types currently available in Empire are:

   passenger
   freight
   munitions
   express

These train types differ in their fundamental capabilities;  some  trains  are
faster  than  others,  some  are equipped to carry many passengers, others are
equipped to carry freight, etc.  The capabilities of each train are  given  by
the show command.  The headings are as follows. For the building data:

                            Concept : Train Types

 lcm  The lcm required to build the train.
 hcm  The hcm required to build the train.
avail  The available workforce needed to build the train.
tech  The minimum technology required to build the train.
   $  The cost of the train.

The headings for the capability listing are

def  defensive armament of the train
spd  the distance/mu for moving (in relative units)
vis  how visible the train is, (relative units)
spy  how far the train can see, (i.e. how  good  the  communication  equipment
     is), again in relative units
rng  twice the distance the guns can fire, (assuming a high technology level)
fir  the number of guns the train can fire at once
mpg  the train's fuel efficiency factor
tnk  number of vehicles the train can transport
pln  number of planes/missiles the train can carry

Trains can be built, scrapped, and upgraded in tank farms (sector type z), are

moved via the navigate command, and are able to move only in  highway,  bridge
head,  bridge  span, tank farm, trade center, and warehouse sectors.  They can
load and unload in all but bridge spans.

Each train can carry a certain amount of products and  has  certain  capabili-
ties.  These  are  listed  under the cargoes & abilities section.  The cargoes
give the number of each product that can be carried.   The  abilities  are  as
follows.

plane  The train can carry planes with the light attribute set.
 miss  The train can carry missiles.
  spy  The train can engage in spying activities.
  pet  The train requires petrol as fuel.
