Rail Operations

As of SEOW v3.2, full support for rail freight and train movement is included. Trains, like other transport units can be produced in factories, brought onto the map as reinforcements, and moved entirely at the commander's discretion. They can also be placed in position in templates (use mobile forms in templates).

Rail Freight

Trains can carry supply and other units as freight. They are slaved to the railway network at all times (using the Strict Complex Ground Movement Mode with the data in the Railway_Waypoints and Railway_Intersections tables). Loading freight on trains occurs in exactly the same way as for other transport units: through the Logistics:Freight tool. The one difference is the "Heavy Rail Freight" setting in the DCS. With this selected, trains may only load heavy freight (armour, artillery) if they are within the Control Radius of a defined Railway Station. If this setting is unselected, trains may load and unload freight wherever they are stopped.

Train Damage

Trains are not well modelled in IL-2, so it is impossible for SEOW to produce partially damaged, mobile trains. SEOW uses a "brittle" model for train damage. That is, if any train car is destroyed then the whole train is disabled and disrupted beyond further use. But that does not mean that all freight it was carrying was destroyed. SEOW incorporates a partial freight damage model, so that if 20% of a train is destroyed, approximately 20% of its freight will be destroyed and the remainder will be unloaded automatically onto the ground around the disrupted train.

Consider the following example. A "Germany_CargoTrain/AA" has 11 wagons and is carrying 5 MG-34 platoons, 2 PzIV-F2 tanks and 20,000 litres of supply. En route to Dmitriev-Lgovskiy it is attacked by a La-5 and has 4 wagons destroyed. The train stops on the track and is rendered useless for the remainder of the campaign. SEOW places damage objects there, but the track is still open for other trains to move through. Since 4 out of 11 wagons are destroyed, approximately 36% of the freight must also be destroyed. Applying this ratio, SEOW determines through a roll of a die that 2 MG-34 platoons are also destroyed, no PzIV-F2 tanks are destroyed, and 7200 litres of supply are destroyed. The remaining freight, 3 MG-34 platoons, 2 PzIV-F2 tanks and 12,800 litres of supply are placed around the wreckage site (the supply automatically appears as a new Supply Drop). The La-5 pilot gets credits for the partial kills. Any following Axis train can stop and load the surviving freight, if desired, or the MG-34 and Panzer units can simply move under under their own steam.

HistorySFX Mod: Train Ruggedness

One of the important HistorySFX Mods is to increase the strength of trains against small-calibre strafing. This was made especially on request from SEOW developers to make the use of trains more attractive. Many thanks to the HistorySFX team for acting on our request.
