5. The German E 19 electric locomotives of 1940 Forward When first viewed models of some of the early German electric locomotives and indeed of the French 2D2 could not understand what was meant by the quill drive The quill drive allied with the oft quoted most powerful got me really intrigued So just had to research them and in so doing got to appreciate the technology that brought these locomotives to the attention of the model builders Being a Pennsylvania Railroad fan realised that the same drive system was used for their GG1 which is also modelled by Marklin Anyway for this treatise would like to review the E19 model built by Marklin in various forms since the 1990s But first have some information on the prototypes which used the standard German Railways AC supply current of 15 000 V at a special frequency of 16 2 3 Hz The Four Prototype E19 The E 19 was the last German electric express train locomotive developed before the Second World War using as a basis the successful E18 The idea was to build suitable motive power for the Munschen Berlin electrified express trains The locomotive was specified for a top speed of 180 km h and a weight of 110 7 tonnes with the option for an extended top speed of 225 km h The ruling gradient on this stretch of line was the Frankenwald ramp and the E 19 was designed to handle this task from the beginning The specifications required the transport of 360 tonnes on th

7. again from the Marklin user manual four double motors and single axle drive which were subsequently replaced by the DB with individual motors There has been speculation elsewhere that somehow DB modified the gear ratios at the same time but there has been no evidence in technical or maintenance reports that support this assertion Of course it is quite likely that the driving characteristics of the new motors differed from the original twin sets Page 5 by Kimball Thurlow 2015 ia 5 7 d FAE A EE OO O O A E A O a a a a s NHI Ti K ELL ee TE THT 1953 Photo Collezione van Kempen da Die Elektrolokomotive bei der DB K Hierl A Ritz Ed Franckhs During dynamic braking the traction motors which are now acting as generators are connected to braking grids of large resistors which limit the current flow and dissipate the converted energy as heat in the resistors instead of the motor Brake intensity can be controlled by varying the excitation of the traction motor field and the resistance of the resistor grid A direct current system can slow the train to about 5 mph 8 km h an alternating current system can slow the train to nearly a full stop Marklin Models of E 19 believe the earliest model produced by Marklin was 3769 in the original DRG wine red express engine colour This was in 1994 The two most recent models the 37691 and the 39190 are described here These models have the same b

10. the best known The full name of the consortium who built the two locomotives of the E19 1 series was Siemens Schuckert SSW Henschel Here are some more technical details SSW equipped the machines with twin engines to each axle of the type WBDM265 which also provided a panel type finish to the floor of the machine This allowed more space within the body for the electrical equipment which included large transformers to reduce the transmitted current to that suitable for use by the motors The series connection of the twin engines allowed a higher voltage at lower currents which saved weight compared to the E 19 0 pair Furthermore the bus bars the low voltage windings and the windings of the built in transformer were made of aluminum in order to save copper for the war effort The aluminium components were replaced with copper by DB after the war to increase reliability Page 3 by Kimball Thurlow 2015 Due to the use of twin engines the brake linkage of the E 19 1 pair is on the outside of the wheel frame so detail differs from that on the E 18 and E 19 0 The rheostatic braking resistors are housed in the hump like roof structure above the main transformer The hump had ventilator grills and could be additionally cooled by directing the air stream through pneumatically operated flaps at the front of the structure The driving motor voltage of E 19 1 was regulated very sensitively with 57 stages compared to 39 stages in the E 19
