The engines have transmission on one side and a 12 Kw DC generator at other end , set up like a giant bus electrical system 74 volt charging with a 65 volt battery every electrical load is fed from battery , compressor single unit ac , overhead blowers lights , controls etc . yes heat is waste heat from engines , one engine feeds floor radiators , other engine feeds overhead heat.
If Conductors are in charge, why are they promoted to be Engineer???
