The EMD SD59MX is a diesel locomotive from Electro-Motive Diesel. Relatively new to the railroads, the SD59MX is remanufactured from the carbody and major mechanical and electrical subsystems of an EMD SD60M "donor". The EFI-equipped 710 engine, however, is all new as are the engine and locomotive control systems. Union Pacific is the first Class I railroad to order them. The engine control system is adaptable to both minimum emissions and minimum fuel consumption modes, depending upon their assignment. ==Union Pacific locomotives== The EMD SD59M-2, more commonly referred to as the SD59MX, is one of the rarest locomotives in the Union Pacific motive power fleet. SD59M-2s are remanufactured SD60Ms. Spotting features: # Wide-nose, so far only the later two-window wide nose rather than the earlier three-window "tri-clops" wide nose and none of the traditional ''40 Series'' cab SD60s have been converted. # Slightly slanted radiator air intakes. # High-adhesion HT-C trucks, reused from the "donor" SD60M, rather than the newer "radial" or "bolsterless" trucks. Nearly all SD40-2s and SD50s used the same truck. # Safety fuel tank like that found on current SD70Ms. Scheduled to be completed: UP 9900-9924, from twenty-five "donors" originally in the UP 24xx, 25xx and 63xx series. Completed: all have been completed. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sd59mx」の詳細全文を読む スポンサード リンク
