Hi,
When I first viewed models of some of the early German electric locomotives, and indeed of the French 2D2, I 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 I just had to research them, and in so doing, I got to appreciate the technology that brought these locomotives to the attention of the model builders. Being a Pennsylvania Railroad fan, I realised that the same drive system was used for their GG1, which is also modelled by Marklin. I have written a complete review of the real engines here (PDF)
http://www.qldrail.net/altkloster/e 19 review.pdf, including notes on the quill drive and dynamic braking, if you wish to download it
Anyway, for this treatise, I would like to review the E19 model built by Marklin in various forms since the 1990s. But first I 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 Münschen - 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 the 13 km long ramp between Probstzella and Rothenkirchen without a helper locomotive.
4 locomotives were ordered by the DRG for testing purposes, the first two in 1938 were built by AEG (subclass E 19.0), and were a modernized version of the E 18. From an aesthetic view, the enclosure panels on the E 19.0 were welded instead of riveted. These engines entered service as E19 01 and E19 02.
The second two by Siemens/Henschel (subclass E 19.1) in 1940, (the units modelled by Marklin), were of a more conventional riveted construction, but had a modern dynamic brake (banks of resistors to create back-emf, to waste current, and to dissipate heat from the motors acting as generators, when no electricity is supplied) housed in a distinctive humped roof structure. This made the E 19.1 strikingly different in appearance to the E 18 and E 19.0.
Marklin Models of E 19
I believe the earliest model produced by Marklin was 3769, in the original DRG wine red express engine colour, as represented by the example preserved in the Nuremburg Transportation Museum. This was in 1994.
Two of the more recent models, the 37691 and the 39190, are described here.
These models have the same body casting, and detail additions such as steps, handrails, and roof-top cabling. While the body is in die-cast metal, the added on detail is flexible plastic.
The wheels sets, motor and electronics are all contained on a main chassis cast in metal, with the upper body retained by a single screw which is accessed from underneath the chassis. In the same location, there is a switch to obtain current from the overhead pantograph(s) if desired. The models will run in either of 3 modes, Marklin analogue, Delta or digital. A Delta model 34691 was also available at time of production of 37691.
The clear plastic side windows of the engine are moulded in such a way, that interior detail relating to the transformer or switching gear is modelled and visible. Some of the cab detail is visible at both ends, with the front windows finely modelled. 3 headlights are lit at each end, from one small bulb (replacement Part# 61 0080).
The real engine has 4 driven axles in a fixed frame, with a leading single axle pony truck at both ends, giving the wheel notation 1Do1. In the Marklin model, each set of 2 driven axles is mounted in a wheeled metal frame which swivels like a bogie, to negotiate model curves. The driving wheel spokes show the detail of the quill drive cups inside the outer rim, each retained by 2 large springs.
The model is driven through flat gears by a motor integrally mounted in one set of the bogie-like frames, with two driving axles. Each of the 4 driving wheels has a rubber traction tire. The digital control electronics are at the opposite end of the chassis to the motor, under which are the set of 4 driverless wheels. The side frames of the locomotive (with brake rigging, axle bearings, and pneumatic controllers) are relief moulded in flexible plastic.
Here is a photo of the flat gear drive train.

Unlike some of my other Marklin models that have a similar gear train, both of these models are really quiet. It is recommended to lightly lubricate (one drop) on each of the axles and the gear set, after 40 hours of operation.
37691 produced in 1997 – E 19.12.
The 37691 model (E 19 12) is painted in the cobalt blue, which was applied in the early 1950s. It has a large flat commutator motor with replaceable brushes Part #60 1460 (see photo below). The model drives very smoothly, with small steps on the Central Station controller. The electronics board includes two screw pots. With the first you can adjust the acceleration and braking delay timing, and with the second, set the maximum speed. One set of DIP switches can be used to reset the operation for analogue or Delta, or to reset the address for digital operation, When delivered new it is set to Address 19 for digital operation, and the function of lights on or off can be controlled (adheres to direction of travel). I believe you can replace the electronics board with an MFX 60947 full sound decoder.
39190 produced in 2002-2004 – E 19.11.
The 39190 model (E 19 11) is painted in the green typical of German coaching stock of the 1950s. This model was produced with what is called a C sine motor. This appears to my eye to be a flat can motor, and the Marklin user manual describes it as “brushless, needs no servicing”, but on which the gear shafts can be lubricated. (See photo below). I guess it has a degree of software control from the electronics. The electronics board on this locomotive, automatically recognizes your mode of operation, whether analogue, Delta or digital. As delivered, the digital address is set to 19 at the factory. The model drives very smoothly, with small steps on the Central Station controller. On the electronics board, DIP switches can be used to reset the address for digital operation, and there are two screw pots. With the first you can adjust the acceleration and braking delay timing, and with the second, set the maximum speed. From the digital controller you can control the function of headlights on or off (adhere to direction of travel), and also turn off any acceleration/deceleration range that has been set (to allow for switching). If you wish to modernize the decoder, you may have to follow Tom and Matt's advice following in this topic, or check with Marklin for a suitable replacement.
