10K City builder temperate 1980 or later with pax, mail, goods and valuables

[CIAsniper]

Open TTD online used to have a 10K City builder temperate 1980 or later with pax, mail, goods and valuabels.

Is it possible to recreate that.... its a nice setup that doesnt take too long.
the ones we have now 3K and 4K are done too fast.... you cant have real competion there
