DR Class 130 family
Encyclopedia
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).

. 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, an over 700 units were produced between 1970 and 1982. Two of the machines are classed as works vehicles as 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 M 62 known as the V 200 (later Class 120) (after reunification Class 220) for freight trains.

Lacking electric train supply and with a top speed of 100 km/h the Class 120s were unsuitable for passenger work; to meet these demands the Lugansk locomotive works introduced the DR Class 130 in 1970; 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 100 km/h (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 120 km/h, and so the DR Class 132s top speed was reduced to that. This class became the backbone of GDR diesel traction. Later six 2,940 kW - 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 140 km/h), class 233 (new 12 cylinder engine) and 241 (new engines with 2,940 kW).

Design

The locomotives are constructed on a steel frame with attached carbody, machines with electric heating are 200 mm longer due to the extra space requirements.

 type with additional dampers. The power transmission is electric. In the original Class 130 a 16 cylinder turbo-charged diesel engine created electric energy for the nose-suspended DC traction motors. (Some rebuilt locomotives have 12 cylinder engines).

Due to construction and the electric power transmission the class 232 locomotives are very heavy. The load per axle of 20,3 t allows usage only on main lines.
The power for the unmodified classes is powered by a direct-injection, 16-cylinder, four stroke, Diesel engine (of type 5D49) delivering when turbocharged 2200 kW The fuel capacity is 6000 liters, additionally 1100 liters of engine oil is used

The diesel engine of the V 300 had significant initial problems; the original crankshaft was made from ductile cast iron but was prone to cracking, particularly after the winter. Thes cast cranks were replaced with forged versions providing running for 20,000 hours, but initially they suffered from low surface hardness - this problem was solved by nitriding the surface, and by locally heating the surface with a CO2 laser.

 in Halle as the Class 130, and this designation was carried into service.

The first locomotive was given to the Leipzig Hbf-South railway, and it was here that the nickname Ludmilla was given to these machines.

The 80 machines in the Class 130 series had bogies and gearing suitable for movement at 140 km/h, but without train heating, so were used mainly for heavy freight service (as task for which they were not optimally suited being geared for 140 km/h with a corresponding lower tractive effort

.)

All but a few locomotives had their top speed reduced to 100 km/h - these locomotives ran as the subclass BR 131.1.

The two test machines for electric heating were given the operating numbers 130 101 and 102, being structurally most similar to the main tranche of Class 130s.

After reunification the machines became members of Class 230, previously this designation had applied to the single DB Class V 200

DR Class 131 / DBAG Class 231

When it became evident that the locomotives would be used mainly for freight due to the lack of electric heating, 76 vehicles were re-geared for maximum speed of only 100 km / h (without electric brake). These 76 machines were classified as Series 131.

DR Class 132 / DBAG Class 232 and variants

When, eventually, electric heating became available for locomotives built in Woroschilowgrad the DR Class 132 were made.

The first two test machines (built in 1972) had a maximum speed of 140 km/h allowed and were therefore considered to be of Class 130 numbers 101 and 102. They were always stationed at the test centre VES-M Halle

, and when incorporation into the new Deutsche Bahn came they were classed as the 754 series.

The Class 132s entered service in 1974, 709 locomotives of this class were built. Under the Deutsche Reichsbahn the maximum allowable lines speed where limited and so in operation these locomotives had a top speed of 120 km/h.

Under the Deutsche Bahn numerous locomotives of this class were rebuilt:

DBAG Class 232.9

Some of Class 234 which had been upgraded to 140 km/h operations were subsequently returned to 120 km/h top speed operation.

DBAG Class 233

These locomotives were renovated and remotorised with Kolomna 12 D 49 M engines, and other more minor improvements: A replacement engine for the 232 series was sought because the engine was reaching its wear limit, Different new engines were tested: a Caterpillar Inc.

However, the Russian producer proved no longer able to supply this engine, as a result an engine largely similar to the 5D49 but with only twelve cylinders. The engine can have sets of cylinders turned off to save fuel at low workloads. By 2003, 65 locomotives had been rebuilt.

DBAG Class 234

Converted for operation at 140 km/h, using higher speed bogies found in the scrapped Class 130s. 64 examples were made.

DBAG Class 241

Ten examples of the Class 232 were converted in 1997 for freight only operation with a new diesel engine of increased power output of 4000 hp, as well as new electrical transmission components (including anti-wheel-slip provision) and enhanced brakes. The top speed was reduced to only 100 km/h.

DR Class 142 / DBAG Class 242

Between 1977 and 1978, six locomotives with a power of 4000 hp (2940 kW) were built, and designated Class 142 in operation. However, it had been decided at the political level that the main lines would be electrified, this there would be no need in future for such a powerful locomotive, and further machines were not built.

The Class 142 was the most powerful single engined diesel in Europe (along with the rebuilt DBAG 241) until 2006 when the Voith Maxima 40 CC

 was built with an even greater power of 3600 kW.

Usage

During GDR times the class 132 pulled everything that was fast or heavy such as express trains on non electrified lines or coal or lime trains of 1800 to 2200 tonnes in weight. Due to the higher axle load and weight their use was not as flexible as the DR Class 118 and DR Class 119

Retirement

The Class 230s were the first of the family to be withdrawn, next went locomotives of the type 231, since without heating they had no use. A few of these classes were acquired by private companies including EBW

The 242 series were also withdrawn from DBAG usage, but have since entered private use.

As of Feb 2009 locomotives of Class 232 with its variants 233, 234 and 241 are still in main line work.
