In 1964/1965, the Deutsche Reichsbahn converted two steam locomotives of the 19.0 series ( Sächsische XX HV ) especially for use as brake locomotives in the VES-M hall . The locomotives used until 1976 were given the EDP series number 04.00 in 1970 .
history
When the Test and Development Center for Machine Management Halle (VES-M) of the Deutsche Reichsbahn, founded by the Vehicle Testing Institute (FVA), was commissioned to carry out detailed metrological testing of the new designs of the GDR rail vehicle industry, an urgent replacement for the worn and outdated brake locomotives was needed . To this end, its manager, Max Baumberg, commissioned his designers in 1958 to work out a project for the existing locomotives with compound engines . The aim was to combine the advantages of the four-cylinder compound drive, which is ideally suited for use as a brake locomotive, with the modern manufacturing and construction technologies that are now available. As early as October 1958, Baumberg submitted a first project, using a 19.0 of Saxon origin as the donor locomotive. Four years and many consultations by the locomotive committee were to pass until on February 11, 1964, 19 015 left the halls of the Meiningen Reichsbahn repair shop as the first “Sachsenstolz” reconstructed according to the ideas of the VES-M . The 19 022 was started as the second Reko-19 in September 1964. Their delivery took place on March 31, 1965, the commissioning at depot Halle P on April 1, 1965. A third locomotive that was planned was not implemented.
The most modern and largest European express locomotive at the time, the Sächsische XX HV, had become a resilient, everyday Rekolok with a completely new look, which was now supposed to do without the original basic defects through numerous modifications.
technical features
During the reconstruction, the two locomotives each received a new combustion chamber boiler , which was originally designed for the modernization of the locomotives of the 03.10 , 39 and 41 series . The type 39E boilers built in the Halberstadt raw material received a significantly shortened smoke chamber without the cut-out for the mixer preheater . 19 015 got the boiler 230/1962, which had been available for almost two years, and 19 022 the boiler 281/64. Such a new boiler cost 63,000.00 marks at the time .
Because of the inadequate flow conditions in the connectors of the steam engines, the VES-M developed completely new welded cylinder blocks and had them manufactured in Meiningen under the supervision of its own welding engineer. While the cylinder diameter and the piston stroke were retained, the diameter of all four slides was changed to the standard 300 mm for standard locomotives. To avoid synchronism of the high and low pressure valves , the control of the steam engine was changed and converted from lag to the lead that is usual with the Heusinger control.
The frame only underwent minor changes, but had to be preshoeed (extended) at both ends to accommodate the new boiler. This increased the total wheelbase to 20,385 mm, which made it difficult or impossible to use on small turntables . The chassis conversion also included the installation of standard wheel sets with a diameter of 1000 mm and 1250 mm. The existing surface preheater was retained because of the newly installed back pressure brake and left in its original place under the boiler. However, it now moved between the drive and third coupled wheels. A new pump mount moved to its former place behind the third set of coupled wheels. Similar to the 01 series , the two new 400 l main air tanks were arranged lengthways between the last coupled wheel set and the trailing frame. The wider Rekokessel also required a new driver's cab with a modified front, transparent devices and storage shafts. Witte smoke deflectors , conical smoke chamber doors , a joint covering of the steam dome and sandboxes gave the machines a very different look.
The 19 015 was coupled with the 2'3 T38 tender of the dismantled H 45 024 high-pressure test locomotive . 19 022 was given a standard 2'2'T 34 tender. In 1967, both locomotives were converted to main oil firing at Raw Meiningen.
Whereabouts
The Rekoloks, renamed 04 0015 and 04 0022 since 1970, received extensive general inspections in the Meiningen Raw material factory in 1972, but were hardly ever used afterwards. The 04 0022 made after the stay at the raw material until it was retired on May 5, 1975, only 4700 km and was dismantled in the Meiningen raw material until October 14, 1975. Despite the most intensive efforts of the Halle railway workers to keep 04 0015 as a memorial or museum locomotive, it suffered a similar fate at the same time. With a mileage of only 422 kilometers (which should mainly result from a farewell drive), it was retired on October 20, 1976. 04 0015 was scrapped in the spring of 1977. Only the impressive drive gear set this locomotive has been preserved and is now at the hub of a branch of DB Museum used Bw Hall P.
