<br/><br/> In order to provide a sustainable transportation option for rural communities in the<br/>Philippines that are close to railways, this study presents the development of a Hybrid<br/>PNR track trolley. These communities typically rely on manually operated or fuel- powered "skits," which are expensive, ineffective, and harmful to the environment<br/>because of their high carbon emissions and short operating range. In order to overcome<br/>these problems, the prototype makes use of a 48 V 1000 W electric motor that is backed<br/>by three 200 W solar panels via a charge controller and a 48 V 70 Ah LiFePO4 battery. Conceptual design, material selection, frame construction, electrical component<br/>integration, and testing under varied loads and ambient conditions were all part of its<br/>development. The results shown that while solar assistance prolongs battery life during<br/>daylight operation, the trolley functions dependably with less human effort. While solar- assisted operation increased efficiency by lowering the discharge rate and extending<br/>travel range despite voltage fluctuations brought on by fluctuating sunlight and load<br/>demand, battery voltage consistently decreased as distance increased across all tests, confirming a direct relationship between energy consumption and travel distance. The<br/>prototype met predicted performance requirements, as evidenced by its overall mean<br/>score of 4.44 and descriptive rating of "Very Good" for functionality, workability, durability, safety, aesthetics, and economy. It is advised that seat foam and backrests be<br/>added for passenger comfort, transparent side covers be added for weather protection, a<br/>protective cover be installed beneath the dashboard to hide wiring and increase safety, and lighter structural materials be taken into consideration in place of heavy tubular steel<br/>to reduce weight and improve
