Allied bombing was hardly happening in 1941, and didn't really cause a major stir among the Germans until July 1943 when Hamburg burned. It wasn't really a factor in Barbarossa...
So... if Allied bombing wasn't
that important in 41, why did they keep over 4,000 flak 88s in Germany & only send 200 in to Russia?
They
knew it was the best AT weapon in the world since the SCW so, you know, a few more could have come in handy.

The real problem is that German trains sucked for long-range resupply. They were designed to operate in Western Europe which had a very dense rail network and plentiful coaling stations. The Soviets by contrast had a sparse rail network - with only a handful of lines connecting the widely separated cities; which often had no coaling stations in between. The German trains simply ran out of coal before they could travel between the great distances of the Soviet rail stations.
To resolve this, they had two options. The first was to use captured Soviet trains - which were larger and had sufficient range to make the trip - but this was done rarely because then they had to keep the track in the Soviet gauge and there weren't enough trains captured in the first place. The second, more time-intensive solution was to build additional coaling stations in between the long distance tracks so that the German trains could make the trip.
Umm...
Couldn't they have just hooked-up another (or larger) coal tender?
Maybe water was an issue too but trains can pull water as well.
It just seems a little strange that this would have been such a huge issue which, on the surface, appears to have a simple solution.
...
And to add to the macabre insanity of the situation, the German train system was apparently still under civilian control in December 1941 - and almost everyone involved in the project went on holiday for Christmas. So while your average Landser froze to death trying to reach Moscow, behind them the new coaling stations that were supposed to help supply him were left unmanned and unfinished - because all the civilian workers were toasting to the troops at home as part of the Christmas holidays.
Now this is just staggering. Everything grinding to a halt during the winter holidays.
This sort of thing doesn't happen on construction projects any more. [/sarcasm]
Whoever was in charge of this project should have been sent to the Eastern Front as punishment.
Oh wait.
On a serious note, these additional coal stations would count as infrastructure upgrades in-game. If a German player wants to properly supply a large Barbarossa, he/she should need to spend some resources in order to perform these upgrades.
From my pitiful attempts at playing Germany, I've tried this and it takes time. Too much time. So, IMHO, appears to be well modelled.
