The UM12C is a type of diesel-electric locomotive manufactured by GE for Southeast Asian rail operators. It is currently in service with the State Railway of Thailand. It was also operated by the Manila Railroad Company and the Philippine National Railways from 1956 until 1999.^[5] While the units for both companies feature a shovelnose layout, the MRR locomotives were single-ended and had a cowl unit cab, the SRT locomotives are double-ended cab forward units.
