just a guess ...
(please, i know ... how should i know.) but let me guess first:
Rail Capacity?
18.1.4. Ground Attack (GA) wrote:[...] Railyard attacks will directly reduce the available rail capacity from that location. This has two primary effects. It reduces the rail capacity on that sector of the rail system increasing the costs of sending units or freight by rail (22.4.4). It also reduces the effectiveness of any depot in the same hex as depot capacity and efficiency is closely related to the size of the co-located railyard (25.7.1). [...]
25.4.1. Railyard Capacity wrote:Railyards represent the rolling stock available for moving units and freight. If the railyard size is greater than 1, then each undamaged railyard factory point, or level, produces 10k tons of rail capacity per turn with the exception that railyards located in the same hex as a national supply source (25.2.3) will produce 200k tons of capacity per level per turn. [...]

- Brest Litovsk Railyard Size = 2

dunno man ... but Brest Litovsk seems the only railyard worth bombing, not?

at least i think that's what keeps the bombers from hitting the other railyards.
So muss man erst mal machen können.
