i believe they used ox carts...
now, thinking again, the religion thing, i believe that multiple religions should be avaliable in one city, so scratch post #92. Also, the trade duhickies could be built by an improvement that allows for another improvement. said second improvement, say, marble freight loading station, would build the marble freight train, which does theexact same thing as a regular marble duhickie, but is much faster, wheeled and unable to move on any tile without a road.
Also also, i think you might could remove the railroad function from the worker's abilities, and if possible make the roads become railroads (still the same function as regular roads though) in the industrial era. Also in the industrial era, you could build a thing called a steam train. It would not be extremely fast, but would be fast. It would have to stay on "roads" and would be a land transport (i know there is a lot of controversy over AI and land transports, but this a good idea, so hear me out). Then, this way, you must load you troops into a train to move them. This would also prevent you from being able to travel across the world in one turn, and i think this is good because it allows for some other interesting things to happen...
other interesting things that happen
the trains (at least in the beginning) are not defended, which means that somebody with something as small as a bandit/raider on horse/camelback could effectively delay a train full of troops being sent to the battle front. Another good thing, thiss allows for a new train capturing strategy, if you make the train capturable (i think it works this way) then in order to capture the train, you must defeat the units inside. that, or they're destroyed, i dont know. Or the game could crash...
Also also also, when you make the preset maps/scenarios, some should involve trade more than others. E.G. Egypt V.S. (rival of egypt)
Desert region. egypt is building the great lighthouse. Their coastal city requires the production from the quarry across the desert. The coastal city has no production whatsoever. (rival of egypt) is trying to prevent egypt from making the great lighthouse. The must steal the camel back caravans being sent across the desert. They then (i dont know what yet, maybe they win after a certain number of turns and egypt wins if the great lighthouse is built by egypt). THat would make for an interesting scenario, i think. How many scenarios do you intend on making?
Anyway...
