Engine locomotive8/8/2023 ![]() The best way to envision how the inside of a cylindrical boiler looks is to imagine a bundle of drinking straws in a glass (only the glass would be resting on its side, not upright). ![]() ![]() The gases move from the firebox forward through an array of pipes called flues, or tubes, in the main part of the boiler, which is filled with water. At the end of the run, the ashes are dumped from the ashpan hopper. On a coal-burning locomotive, the build-up of ash is controlled by shaking the grates so the ashes fall to the ashpan below. Hot gases rise from the firebed to the upper portion of the firebox, or combustion chamber. The production of steam begins with the fire, which rests on grates at the bottom of the firebox. The essential action of any steam engine, stationary or mobile, is that of steam under pressure (200-300 PSI for most locomotives) entering a cylinder-piston assembly and pushing against the piston as it expands in an effort to reach normal atmospheric pressure. There are two basic areas of activity on a steam locomotive: the boiler where steam is made, and the engine (cylinders, rods, and driving wheels) where steam is used. In fact, entire books have been devoted to the subject. This mechanical honesty has long captivated onlookers and invited study, but many still wonder just how steam locomotives work. Unlike modern machines, the steam locomotive - which underwent few fundamental changes in 125 years of development - openly displays many of its parts. Extensive fault diagnostics and tolerance features with fault data pack recording for several seconds during fault occurrence.There’s no denying the drama of a powerful locomotive, but how do steam locomotives work? Western Maryland Scenic Railroad‘s 1309, a 2-6-6-2, was photographed during a 2022 Trains Magazine photo charter.Various auto and manual test modes, including load box, auto test for relays, manual test of inputs and outputs, excitation test, chopper Test, radiator fan tests are available.TFT LCD type display with graphical user interface.User-programmable settings (through laptop) allow easy customization to work with various makes and models of locomotives, with different combinations of traction equipment for varying capacities. ![]() MMG control system is more accurate and reliable because parameters are set in digital mode.As transfer work required high tractive effort but not much speed, Medha has designed transfer locomotive consists of two engines with required horsepower and chopper & traction motor configuration for high tractive effort, on an elongated locomotive frame, and with four driving axles. Medha's Mult- engine locomotive comes with center CAB for two GenSet configuration.Īll auxiliaries are electrically driven and which gives more flexibility in equipment layout as well as giving best possible options in saving the fuel consumption and for extracting more traction power from Gross HP. Multi-engine locomotive has an inbuilt concept of activating/ deactivating the engines dynamically with respect to load demand and it gives the best possible options in reducing both fuel consumption and exhaust emissions. Medha offers Multi-engine locomotive for freight & goods application. ![]()
