The DR 130 family of locomotives comprises the DR Class 130 (''DBAG Class 230''), DR Class 131 (''DBAG Class 231''), DR Class 132 (''DBAG Class 232'' as well as Classes ''233'', ''234'' and ''241'' produced through modifications) and DR Class 142 (''DBAG Class 242''). They were produced in the Soviet Union in Luhansk, Ukraine from the 1970s onwards, and were imported into the GDR. After the reunification of Germany the Deutsche Bahn (DBAG) inherited them and continue to make use of them mainly as heavy freight locomotives. Nicknamed ''Ludmilla'', over 700 units were produced between 1970 and 1982. Two of these machines are classed as works vehicles with the designation Class 754. == History == During the 1960s the East German government decided to focus on diesel traction. Due to RGW guidelines the GDR had to stop their production of diesel-hydraulic locomotives. Instead GDR imported heavy-duty engines from the USSR, starting with the a version of the M62 known as the V200 (later Class 120; Class 220 after reunification) for freight trains. Lacking electric train supply and with a top speed of the Class 120s were unsuitable for passenger work; to meet these demands the Luhansk locomotive works introduced the DR Class 130 in 1970 capable of a top speed of . Unfortunately the soviet industry could not provide an electric heating feature, therefore the engines were restricted to freight trains for which their gearing was too high. Subsequently the 'DR Class 131 with a reduced top speed of (and thus a higher tractive force) was delivered for freight services. When in 1972 an electric heating system was available, two prototypes were constructed. Due to poor track conditions in GDR the top speed was limited to , and so the DR Class 132s top speed was reduced to that. This class became the backbone of GDR diesel traction. Later six DR Class 142 units were produced in 1977, but due to the planned electrification of many major lines such powerful engines were not necessary any more. After reunification Classes were renumbered according to West German practice, thus as mainline diesels the prefix "2" was necessary: the Class 130 was renumbered to DBAG Class 230 and Class 131 to DBAG Class 231; both were soon pulled out of service. The renumbered DBAG Class 232 are still in service and have taken over many freight services in Western Germany. Some Class 132s underwent reconstruction under DBAG ownership, forming the classes 234 (top speed , class 233 (new 12-cylinder engine) and 241 (new engines with . 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「DR Class 130 family」の詳細全文を読む スポンサード リンク
