In my AH there are large airships which are more advanced than those in our time line, i.e. real history (hereafter known as "OTL"). Country A has invaded country B and B needs to get some 'marines' to the threatened cities quickly (more quickly than marching/driving).
Country a B has good rail network but I'd assume large airships may be slightly quicker to get light infantry/bicycle/motorcycle troops to the threatened area - to be followed up by train-borne heavier troops in slightly slower time.
My question is this: how many troops could a large airship carry? (Obviously they don't need the level of luxury that the passengers in OTL enjoyed.)
