Rail Technical Strategy intends to achieve 4C's targets, which are reducing carbon emission, increasing rail capacity, decreasing rail cost, and improving customer satisfaction. Reducing fuel usage and cost in rail travel depend on the development of more efficient operation and management. This thesis presents investigation of different energy saving strategies for diesel passenger trains. Stabling and power control are the main part in the research. In order to obtain and analysis the methods, the thesis explores, through a series of case studies, a number of suggestions for different operating companies. The first case study relates to reducing stabling time or engine idling time and minimise fuel usage by selectively shutting down the running engines. The second case study mainly focuses on energy calculation and analysis about Class 221, combined with discussing eco-driving. The final part of thesis roughly introduces the traffic management system for assisting energy saving and introduce the new traffic control loop combined with advanced automatic system. Overall, the thesis provides evidence that technology packages (shutting down engines and eco-driving, TMS) could reduce energy consumption, decrease green gas emission, and reduce rail cost
