The TRAINOSE Class 520, also known as the AEG DE IC-2000N, is the oldest class of trainsets operated by TRAINOSE. They are diesel-powered, and can be seen operating in DMU-5 or DMU-4 configurations. They were built in 1989 and 1995 as the class 601 and 651, respectively, from the cooperation of West Germany's AEG and East Germany's LEW, and for about two decades they were the spearhead of the InterCity services. Sometimes, DMU-4 trains can be seen operating coupled with another unit to increase capacity. In total, there are 20 such trainsets, 12 DMU-4 and 8 DMU-5.

The DMU-4 sets are numbered from 520 101 to 520 412, while the DMU-5's from 520 151 to 520 558. The first batch of trainsets can accommodate up to 180 seated passengers, 36 in the first class and 144 in the second, while the second batch can accommodate up to 214, 75 in the first class and 144 in the second. They are equipped with MTU diesel engines which produce a combined power of 2170 kW (1050 x 2 diesel motors MTU 12V396TC13 with supercharger M.T.U ZR170/137) allowing the class 520 to reach speeds of up to 180 km/h.
