After digesting these figures, I have the following recommendations:
... and then there's the Rail D bonus. It's a white elephant, even worse than Asia in Classic. Nobody but nobody is going to collect this bonus until the game is decided already in their favor. Yet, you already have more than enough bonuses, so splitting it up doesn't look like a good idea. You could palm some of its regions off to other rails maybe, but this would only make the other rails non-viable while not really helping Rail D significantly. In light of the fact that the number of total deployable regions on the map is a very unfavorable number, I would be inclined to recommend that you chop out some of the stations in Rail D... but that's just my first thought and any other idea that might reasonably reduce the borders of this bonus would be welcome.
As for your neutrals... they could be moved to better spots to prevent dropping bonuses. The most obvious move to me is the neutral on the F-Rail. Move it to Tblisi Station, since that's a very droppable bonus at the moment and needs a neutral. Thus two birds with one stone.
The second thing that I would do with the neutrals is to get rid of the neutral on Rail H. It's not needed... if it turns out that you need the neutral for your total region count to be a golden number, move it to Rail L.
Finally, as mentioned earlier the total number of deployable regions for this map (73 regions) is a non-golden (one might say black) number. Some adjustments need to be made to either increase or decrease it to a golden number.

P.S. I didn't give a rationale for my suggestions for raising or lowering the bonuses (other than Rail D), but if one compares the values between like rails, most of them are self-explanatory. Rail M is too good of a deal for +2... I think that a bonus should not be both easy and more efficient than larger bonuses; rather a small bonus should be a tradeoff (easier to take and hold, but less efficient). Otherwise it dominates the strategy disproportionately.
Here is my solution for Rail D
It's still a large bonus, but it now gives 82 regions so only to have to start neutral to get the 80 golden number.
I'll get back to the other side adjustment like M shortly...need some more sleep.
