STRATEGIC BOMBING
What certainly does not work out is Strategic bombing on tanks/plane factories. As Germans you'll usually lose more planes than you'd deny the Soviets.
What works at times is RAILYARD/PORT to stop/limit movements by sea (Leningrad) or by rail. But especially the latter having a range of 30 Hexes for requesting trains makes it hard to execute but you see an example here for T1.

Reducing the enemy's logistics by Air is something we need to figure out how to do by air (besides the interdiction example I shared above). So GA Railyard + GA Railway in combination....

German Air Force Operations in Support of the Army / Interdiction of the Battlefield
[...]In the 1-11 September 1941 period the V Air Corps committed relatively weak forces to interdict the rail route leading from Kharkov through Poltava into the pocket area, but at the same time dispatched units to attack all other rail routes leading westward and southward from the west through Kharkov and farther east.

[...] The primary target was railway rolling stock. During the most crucial periods of the battle, for example on 8 September, units executed as many as fifty strikes against locomotives and against complete railway trains. Special type SC-100 bombs were used repeatedly. Frequent use was made of 4. 4-pound (2 kilogram) bombs in containers in an effort to cause fires.

It is no longer possible to determine to what extent the Russian rail system was permanently damaged. The fact that only very few man-made structures existed in the areas under attack resulted in few possibilities to do any lasting damage. However, reports from the period under discussion mention large numbers of trains halted and numerous trains derailed. Although it must be said that the effects of each individual air attack were not always great, the cumulative effects of the operations can be considered as adequately satisfactory. The Russian side was no longer in a position to maintain properly scheduled traffic, to move in essential supplies to the troops inside the gradually developing pocket, or to move the Russian forces out of the trap which was closing. Large numbers of trains were frequently observed halted on the main lines. At some points, however, and even within the area under German attack, the Russians did succeed in moving in reserves from the outside. On 18 September, for example, the Second Panzer Group came under attack by a Russian tank division and a cavalry division newly arrived in the area.[...]

25.4.1. Railyard Capacity
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.[...]

level? factory point? which is it ... or both?

25.4.2. Damaged Railyards
Railyard damage will reduce the amount of freight that would be shipped and unloaded at a railyard depot in the hex. There is a percentage chance equal to the railyard damage that the amount shipped to a railyard depot will be divided by 10.
If a railyard is damaged either due to being recently constructed or captured, then it will automatically try to assign any available construction unit to speed repairs.

i'd like to reduce the future rolling stock of the enemy ... how to do if not by strategic bombing? GA railyard is enough?

You can't really reduce the future stock as you describe. Railyards repair and their capacity to do so is unlimited. So you can only really affect the present situation. Your ideal target would be a railyard that is likely to be supplying large amounts of troops without many backup options elsewhere - a situation that is much more likely in the South than in the more developed North. Note that what you'd be doing is targeting the railyard facilities themselves rather than the rolling stock.
