- The GE U30C is a six-axle locomotive built by General Electric from 1966 to 1976. With 600 units sold, the U30C proved to be a viable alternative for customers who were unable to purchase SD40s from Electro-Motive Diesel (EMD) due to production backlog. Throughout its ten-year production span, the U30C was known for reliability issues concerning its electrical system. However, most railroads were assured of the reliability of the GE Model 752 DC traction motor, and began to place orders for U30Cs starting in 1966. When production ended, the last U30Cs carried pre-Dash 7 specifications, which would be carried in its replacement, the GE C30-7. The U30C served customers of all kinds, from mining, to general freights, coal trains, and even as a power source unit for the Department of Transportation's subway-car test tracks in Pueblo, Colorado before a connection from the commercial electric power grid could be established. Not to be outdone in the freight sector, GE produced a passenger version of the locomotive, the GE U30CG. The U30CG only sold six units for the Atchison, Topeka & Santa Fe Railroad. When most U30Cs were being retired due to old age and mechanical or electrical problems, General Electric initiated a rebuild program where older Universal Series locomotives would be upgraded with the latest technology and fuel-saving systems. GE would then strip the locomotive down to its frame and engine, and completely rebuild the locomotive with new components. When completed, the unit would receive a new designation: (R for Rebuilt frame of traded-in locomotive). In the later years, the rebuild frame was discontinued, and a brand new frame would be used, re-designating the locomotive as (N for New frame). The only external difference was a large vent on the fireman's side ahead of the engine compartment. The final variation came with the discontinued frame of the Universal series and instead, using GE C40-8 kits. This new model also featured a microprocessor, officially designating this locomotive as . A variant of the U20C export locomotive was known as the U30C. This version is unrelated to the U30C built for North America. (en)

Okazał się sukcesem i był kupowany przez firmy kolejowe w USA, które nie były w stanie nabyć nowoczesnych wówczas lokomotyw EMD SD40 i EMD SD40-2. Wyprodukowano także 6 sztuk w wersji GE U30CG przeznaczonej do prowadzenia pociągów pasażerskich. Ze względu na zużycie, większość lokomotyw U30C zezłomowano w ostatnich latach, a tylko nieliczne zmodernizowano w ramach programu GE Super 7. (pl)
- U30C型柴油机车是美国通用电气公司于1966年推出的一款柴油机车。这款机车是在U28C型柴油机车基础上发展而来的六轴柴油机车，其主要竞争对象是易安迪的SD40、SD40-2型柴油机车，以及美国机车公司的。型号当中的“U”代表“通用”系列、“30”代表单节功率为3000马力、“C”代表机车轴式为Co-Co。同级的后继产品为“Dash 7”系列的C30-7型柴油机车。 U30C型柴油机车采用底架承载的单司机室外走廊式车体结构。根据布置在冷却室两侧的空气滤清器的结构类型，U30C型柴油机车还可以分为第一期和第二期，早期生产的第一期机车均安装油浴式空气过滤器；从1968年起的第二期机车的下部散热器进风口改用纸质滤清器，而上部散热器进风口则仍然使用油浴式过滤器。机车走行部为两台FB3型浮动摇枕式三轴转向架。机车装用一台16气缸、四冲程、涡轮增压的FDL16型中速柴油机，额定功率为3000马力。传动系统采用交—直流电传动，柴油机直接驱动一台GTA-11型三相交流同步发电机，发出的三相交流电经硅二极管整流器整流为直流电后，供给六台并联的GE-752型串励直流牵引电动机。 U30C型柴油机车于1966年11月投入批量生产，生产一直持续到1976年10月停产为止，通用电气公司共生产了600台U30C型柴油机车，也是整个“通用”系列柴油机车之中销量最佳的车型，共有18家美国的一级铁路公司购置了该型机车，其他用户还包括大型工业企业、美国运输部、等。此外，许多U30C型柴油机车从美国的铁路公司退役后，经过翻新后被转售予墨西哥国家铁路。 (zh)
