I have chosen to stick to a scale roughly equivalent to the current vehicle scale.  This prevents representing some items like bogie flats in a single hex.  The more important impact is that an armoured train in the game at one car per icon has a much lower density of firepower than a prototypical train of the period. A couple of approaches can be taken. The first is to beef up the weaponry used in the secondary slots. The second is to use "no icon" units stacked in the same hex to represent additional armament.

Most German trains seem to carry 10-20mm of armour before sloping giving in game armour ratings of 1-3. 

All cars have carry cost of 255 and move 0

Locomotive
Because of the icon scale, I have only been able to represent a tank engine - that is an engine that carries fuel and water in a built in bunker rather than on a separate tender. All were large and some carried an AAMG. Early armoured models of all nations had closely fitting armour that complicated maintenance and created numerous shot traps. Later versions used flat sheets of armour held away from the loco proper which may warrant some anti-heat ability as per shurzen.

carry capacity: 0
armour: 0-2 with perhaps 1-2 points of heat.
size: 3-6
armament: 1 dual AAMG max

Tank carrying cars
Used by Germany, Poland and probably others.  The tank could either operate from the car providing support "over the boards" or could off load and fight away from the train.  The in game problem is that a tank passenger cannot fight while loaded. A suggested fix is to make the carrying car a duplicate of the carried tank but with much reduced ammunition - perhaps 2-3 shots. Once this ammo is depleted, the player will have to off load the tank to continue to use it with the carrying car only able to make a small contribution to the fight.

carry capacity: 255
armour: as per carried tank
armament: as per carried tank

Artillery car
Based roughly on a Polish model of Austro-Hungarian ancestry, this car represents a number of different types of rolling stock with forward firing guns.  As a base type I used a pillbox to limit the field of fire.  However, limited playtesting has seen this car destroyed by infantry fire.

Carry capacity: 0
armour: 2-3 points but may need to be increased.
size: 3-6
armament: as per prototype - usually a forward firing howitzer and 2+ mgs.


Passenger car
As with the tank carrying car, there is a problem when trying to represent rifelmen firing through loopholes etc.  A suggested approach is to use an AA MG or rifles to represent the carried squads fire power.

carry capacity: 26 as apc - roughly 2 sections
armour: 0-2 points max
size: 4-6
armament: rifles and maybe mgs


Flat cars
Flat cars were normally used at either end of the train to detonate mines etc.  Some carried mgs, riflemen or sometimes AT guns.  On adhoc track guarding trains some protection was provided by sandbags.

carry capacity: 13 or as required
armour: 1-2 points if sandbagged with perhaps 1 point heat. Open topped.
size: 2-3
armament: rifles, mgs etc as required. Support weapons should use the turret flak version.

Gondola
A gondola is a usually low sided open topped car used for transporting looses and boxed goods.  I have chosen to use the gondola to represent open topped cars carrying steel or concrete armour.

Carry capacity: 13 or as required
armour: 1-3 points. Open topped.
size: 2-3
armament: rifles mgs etc as required support weapons should use the turreted versions.


Flak cars
Fortunately, at least for some German cars, existing flak turrets and mounts were used on flats and gondolas.

carry capacity: 0
Armour: 1-3 points open topped plus flak gun armoured as per prototype mount
size: 2-3 plus points if large turret used
armament as per prototype.

Pursuit cars
The BP 44 trains carried in theory 2 pursuit cars based on a Pzkw IV turret with 75L48 gun. Not much more than an icon change is required. Judging from photographs, the pursuit car may be a little lower than the stock Mk IV and may warrant a size reduction.
