More Circuit Connections

[Silt]

Many objects have the ability to send things about them into the circuit network (e.g. energy percentage of accumulator).
It would be great if more machines would allow you to do this like send contents of various machines, output of solar panels, heat in boiler/heat exchanger, performance of steam engine, etc.

I also find the connection between trains and circuits insufficient. You could add a "pressure plate" (2x2 or bigger) that can be placed on rails and outputs the contents of whatever entity is on top of it (car, tank, train).
This way you can easily compare e.g. how full different cargo wagons are.

The second half of your suggestion has already been suggested in the following thread:

viewtopic.php?f=6&t=51387 Rail car/locomotive scanners

As I have already stated in the respective threads, I agree with both suggestions.
