Cargo can change from bus/trams to trains anyway, either from manual orders or with cargodist. It's probably also worth mentioning that cargo quantities are usually more limited at first. Primary cargo especially grows slowly. Passengers can grow very quickly if the player understands the city growth mechanics (the count is a function of city size), but even with cargodist if you make an actual network they will dictate their stop. For me the appeal is more the mid-late game micro-optimisations, like how to make a junction work when there's constant incoming trains.
