))Relics
We can found it when buliding roads, depots, stations, airports etc. Or even found in the sea when building docks, canals etc.
After found the relics occasionally, we can deliver it to a museum (Which may be is a new industry)...

Powerlines
Also, the power station can transport electricity to industries to increase production rates, like 'Simutrans'.
I don't know if it is useful to here.
*PS: I do not make graphics, so if any graphics maker is interested, feel free to do it. (Tell me first)
