'''MD3''' (model designation '''Lp050A''') is the name of a [[Chilicxqua|Chilican]] diesel locomotive class made for the [[FEC]] by [[Hugo Tractive Works]]. The MD3 is part of the MD family of locomotives, small family of domestically designed and produced diesel locomotives in Chilicxqua from the 1970s and 80s during it's great reconstruction.

MD3 (model designation Lp050A) is the name of a Chilican diesel locomotive class made for the FEC by Hugo Tractive Works. The MD3 is part of the MD family of locomotives, small family of domestically designed and produced diesel locomotives in Chilicxqua from the 1970s and 80s during it's great reconstruction. In use, the MD3 and its smaller cousin, the MD4, is used primarily for shunting, but is also employed in cow-calf configurations for short-range cargo trips. The locomotive is heralded as one of the most important tools of the great reconstruction.
Technical Data
It is a decently small locomotive, with an independent locomotive having a 370kW power output engine. The engine is coupled to the wheel sets through a hydro-mechanical transmission with a quintuple gearbox.
Engine
The MD3 and the MD3B, the calf variant with two engines, are powered through a Koszalin Ke350-2, a four-stroke, twelve cylinder diesel engine that can be ignited either through a pneumatic starter system or through an electric starter system, the former being used in events where the batteries are dead. The Ke350-2 engine is notable for being used in the T-34-85 tank, the AFV having seen great use during Chilicxqua's War for Liberation. The choice to use these engines, and also buy others from Kolodiya, Polvokia, and Vihoslavia, was to save on costs since many mechanics that worked on these engines could be put to use fixing these locomotives. The engine was reputable for ease of maintenance and it's power.
Gearbox
MD3, MD4, and MD3B all share the same hydro-mechanical transmission with the same CeH050-series quintuple gearbox with a two speed range. While the CeH050 had a 55km/h top speed, it's first versions were far worse and temperamental in practice during the first years of production, resulting in train operators maintaining a slow 45km/h as the clutch either disintegrated or the transmission was assembled wrong, which could cause the system to stick, break entirely, or be borderline sluggish. This was all due to defects in the design of the transmission, poor materials available for manufacture, and poor quality control practices, which were only brought up to satisfactory levels come the second year of production. CeH050G, entering circulation in 1983, would be the final iteration of the transmission series after numerous redesigns, with only a 12% chance to fail.
