Thanks NekoMaster for you comments appreciated people giving suggestions and ideas.
I think removing water cargo would be fine as water is rarely transported in huge quantanties by rail or road, its usually transported by river, viaduct, or pipes.
These days I don't think water be carried by train, but used to do so in Australia once upon a time. When I worked on the North Coast Line in the 1970s and 1980s a Water Train would depart Newcastle once a week delivering water to stations and sidings that did not have laid on water. There be water tanks along side the lines that train would stop and refill. These trains operated pretty well all over the State to supply water to remote places. But to make this realistic in game be hard as unable to have a train say of 10 wagons of water and deliver only one wagon at each location that there are water tanks. So removing this cargo would be ok.
Also, I think that it would be alright to merge Fruit and Veggie cargos into one cargo, perhaps called "Produce"
I think this be a good idea and it will free up a cargo. (Like to have 2 types Fresh Produce to represent Fruit and Vegetables and maybe Meat).
Lastly, I don't think its a good idea to split up live stock into multiple cargos, its probably best to keep it as Livestock and leave it up to the players imagination of what it might be, which may be helped by the place they come from (like a farm having pig sprites would most likely be producing pigs)
Thinking of this idea mainly so I could add a Bacon Factory .. but as you say if the farms have sprites to represent what the are producing would help .. up to the player then if they actually carry pigs to the bacon factory for realism or make bacon out of mutton from sheep.
The Shopping center thing, well you could instead have a "Shopping Center" or "Shopping Mall" which would be a large "Industry" type building that must be built in or around towns (not all malls are built IN town, some are built on the edge of towns and people get there by car or transit). YOu could also have a smaller shopping place like a "Shopping Plaza" or "Strip Mall" which would be a town building much like gas stations or hotels, as I find plaza's appear in just about every major city and town in real life.
Separating the Shops in to two smaller Industries I think better idea. I started to make a outer suburb of old style house with larger back yards. Just a 4 x 4 size with 8 buildings .. could deliver Mail here and maybe food but not produce anything.
I hope to do another one just with shops with a Post Office .. deliver foods and Goods here and produce Mail .. something like that.
Lastly, GEAR isn't support to be a transportable cargo, it was ment for Regearing of NARS 2.0 locomotives. It might cause weird things if you had GEAR as a transportable cargo.
I had no intention to use the code "GEAR" .. just seeing that gave me the idea for a cargo where I could supply Railway Stores to the Workshops. I'd give it a different code maybe VPTS for Vehicle Parts.
Heres a suggestion for a CARGO/INDUSTRY, you could include a Bulk Terminal/Port (if its not already included, I havent played Auz Industries in a while), which could accept Iron Ore, Coal, and Uranium Ore.
Already do this .. the Port accepts Coal and Iron Ore and one of the Bulk Terminals accepts Wheat, Grain and Sugar and the other one Wool and Cotton .. as if Exporting.
Making these changes give me the chance to Introduce 3 different cargos .. see what ideas I can come up with.
