A method and apparatus of operating a turbo-charged diesel locomotive engine 10 to facilitate controlling pressure in an engine cylinder 146 is provided. The method includes determining 266 an allowable peak firing pressure for the turbo- charged diesel engine, determining 268 an actual peak firing pressure, and comparing 270 the allowable peak firing pressure to actual peak firing pressure to control the operation of the turbocharger 12 for controlling peak firing pressure. The apparatus includes a diesel engine including an intake manifold 114, an exhaust manifold 116, an electronic fuel controller 138, a turbo-charger 12, and a motor-generator 15 7 coupled to the turbocharger and operable to at least one of increase turbocharger rotational speed, decrease turbocharger rotational speed, and maintain turbocharger rotational speed, and a controller including a first input corresponding intake manifol d air pressure 148 and a second input corresponding to fuel injection timing 144 f or the engine and including as an output a motor-generator configuration signal 158 .
