// cab logic of an electric locomotive with induction motors, modelled after the Vectron .fiz.
// stage 1 of the vehicle graph: only logic and cab blocks are available, so the pantograph, the main circuit
// and the inverters are represented by timers and constants. the combined power/brake lever is split into
// a traction demand and an electrodynamic brake demand, which will drive the inverter blocks in the next stages
