Yes. The engines would have to run off fossil fuels if electricity is intermittent (This is still the standard, anyways) and a communications system based around local power sources would have to be used. It would be the job of the railway company to keep its stations powered (i.e. fueled). If the railway company can control power to its infastructure, it can run successfully.

Yes, energy is simply a way for things to change, therefore it is needed. Without energy flow (where energy is either gone or constant) a substance will remain the same.
The Boltzman's constant is the physical constant relating to temperature to energy.
An organism needs energy and constant supply of materials to grow and develop.
The body has reserves of energy it can spend when there is no constant food intake. The cells can take energy from certain parts of the body as glucose. These parts can be the liver or the skeletal muscles, which particularly has glycogen (more difficult to assimilate into energy).
While the TOTAL amount of energy remains constant, on the other hand, useful energy can, and will, be converted into unusable energy.
coustant energy requirement..
infer that the total mass energy in the universe is constant
the value 'n' of meter constant indicates that consumption of energy is n KWh.
The rate constant decreases.
Yes. An object's potential energy is relative to an arbitrary constant. Depending on the choice of that constant, the potential energy can indeed be negative.
- If energy input is constant, then (E x I) is constant. - If 'E' is constant, then 'I' must also be constant. - Your ammeter must be failing.
