How is it going to be powered?

The LRT lines are going to be powered by overhead wires and they are going to be grounded by their wheels just like the streetcar

The commuter rail line can be powered by hydrogen fuel cells, diesel electrical, fully electric, or Battery electric, We would most likely hydrogen fuel cells or battery electric instead of the diesel electrical, or fully electric since diesel is bad for the environment and fully electric is too expensive.

The trolley buses will have two cables. One of the cables is for the power it and the other cable is for grounding since unlike the LRT and streetcar they don't have a metal wheel which lets them be grounded by itself

The bus would likely be diesel. since it going to be going a short distance.
