Don’t like bottling up the Austrian fleet like that… I suppose it depends what you do with the Italian entry. I like giving Austria more options, such as invading Cyrenaica; they then have to choose between taking advantage of this (bringing Italy into the war early), or leaving Italy in peace for a turn. Another factor is if you allow Italy to move and build before being at war (I don’t.)
I still think there is a case for unlimited rail movement along friendly lines, though never into combat (you can reinforce a contested area if there is no attack there this turn). Its up to players to disrupt enemy communications by blocking long rail movements.
Again, my point is that for every war from the American Civil to WWII the nature of the combat was dictated by rail movements allowing nations to heavily reinforce their fighting fronts in time to prevent their collapse, or shift major contingents from front to front in a short time (equivalent to no more than 1 game round), thus leading to battles of heavy attrition.
There really should not be large forces in transit away from the battlefields.
Should rail (i.e. move 2 spaces) be allowed involving Persia & Afghanistan? Don’t think so.
