My Fine Models E71 scale 1 model

New 20Dec2021, updated on 25May2022 (spur1info, E70, fig.9, Loco meditation at low speed). In work. This note is in subgroup My Crocodile locomotive pages of group Models. I will try to describe this very fascinating and beautiful model from Fine Models in Germany, of a rather small Prussian “proto Crocodile”, predating the long “Swiss Crocodile” (SBB Ce 6/8 II-III) by some five years. I hope that the contents will reveal my liking of this model!

Background and references

Fig.1 – The Preußische E71 (Var.1 of K.P.E.V. EG 513) from Fine Models on My Shelf’s Railway Strip (MSRS v.4.0)

The model on fig.1 probably is maximally twisted, half way into my home made switch with radius 1.02 meter, from a left to a right curve.

Initial reference

I first discovered this model in a magazine. Read about it at 201:[E71, Preußische EG 511 bis 537].

German

About the E71: Preußische EG 511 bis EG 537 (this is the text that was used in the User Manual (translated: Prussian EG 511 to EG 537). K.P.E.V. is Königlich Preußische Eisenbahn-Verwaltung (translated: Royal Prussian Railway Administration) – which seems to be some alias for Preußische Staatseisenbahnen (translated: Prussian State Railways).

About the per design preceeding the E71, the EG 2, later called E70: Bayerische EG 2 (translated: Bavarian EG2). I was built for the K.Bay.Sts.B (KBayStsB) Königlich Bayerische Staatseisenbahnen (translated: Royal Bavarian State Railways). It was ordered in 1912 and probably designed quite early, but not delivered before after WW1, in 1920. I think it has a stiff frame with two bogies mounted in each end, just like the Norwegian EL 1 (EL1) (more below).

Collision avoided!

Observe that on both of the above pictures the driver has halted for a second, since the cabin light is on. It is switched off automatically when the loco starts. Driver?

From my album

Fig.3 – The articulated E71 30 at Verkehrs Museum Dresden and a stiff EL1 at Norsk Jernbanemuseum (Hamar)

Aside: for the right, bottom picture, read about it at [8].

I have actually been inside one of the remaining E71 at the beautiful Verkehrs Museum Dresden (Transport Museum Dresden) [5]. Plus, a stiff, single body version of it, the NSB EL 1 (EL1) at Norsk Jernbanemuseum (Norwegian Railway Museum) at Hamar in Norway [6]. This single frame has one bogie in each end, just like the mentioned Bavarian EG 2. But the original E71 is a true articulated locomotive with two pivot joints, three body parts altogether – and it could certainly twist like a crocodile. In initial comments (above) I discussed whether this locomotive could be categorised a “crocodile” at my. There is no doubt: it is a crocodile type locomotive!

Fitting the driver

Fig.4 – Fitting the driver (Mr. Lutz from Fine Models) into the E71 (PDF) at the end 2 cabin

The loco didn’t come with any driver mounted, but it came with a nice, standing driver. He is Mr. Lutz, nothing less, “handmustered” (hand made) and very well dressed up, with his eyes fixed on the track ahead. It was possible to fit him in, standing in front of the seat (which may not be tilted upwards), holding his hands on the steering wheel. But I needed to make a base for him that I fit on the floor behind the hot air input, as I did with the Märklin loco [7]. I basically used the same procedure as described there.

Also this time I didn’t want to glue him in place. (Him? I’ll get a second driver as well, one of these days.) I have no idea how you do this out there, but this works rather ok. Comment below for any better ideas!

Fig.6 – Waiting for switch direction

I started with a small piece of thick paper and gradually made newer that were larger, and then also had to trim them. But you can stand on the shoulders of this giant (..me!) and just print out the PDF (here). It should be to scale if it’s A4 – you can check that the red line is 100 mm long. If so, you can cut out [1] in cardboard and then fit it in. Observe that I did the scan of the bottom of the base. The red marks show where I bored holes for the copper straps, which I soldered in place, since my base is some thin electronic circuit board which just appeared in my box. On the paper template base I drew a grid and saw where the figure could stand [2]-[3]. It’s really keyhole surgery, or rather zero invasive surgery, so I used tweezers (with plastic on the tips!), plus that I took a plastic tube and used dental floss to hold around the figure [4]. The right photo is shot before I did the wider and better version, seen on the leftmost photo of [4]. Don’t tie the floss in a loop, because you want to just pull it out to remove it. I painted and drew some lines on the base to make it show somewhat like the wooden floor.

This door never closed precisely into position, as did the other doors, when I received the loco. I now saw the problem. There is a magnet inside, just beside the feet of the figure, that will click the door into position. The problem was that the door was a little bended. I carefully bent it with my fingers, and now it shuts perfectly well. This magnet may stop the figure’s base, but if you lower it into and below the magnet, it should work. (Aside: The locking mechanism also was a problem for both of the fuse compartment doors. These also have magnet based locks, but the doors came as more or less friction based, hard to open. But I did succeed on carefully pushing the tab with my fingers to get the tab ready for the magnets. But the tabs may have been placed some small part of a millimeter too far “out” on the door, by design. With all respect (the model is very well designed and built) miniaturisation isn’t easy for anybody, I assume.)

Once in position, after trying a lot of times – I pressed the feet into the straps, almost with an inaudible click. Now the figure stands firmly in place without any glue. And the base is also loose. Meaning, if I tilt the loco or turn it upside down I may have to refit the base and driver.

You can see the result in the lower row of pictures. It’s just so nice.

E71 model

Which end is which?

On my model (Var.1 of K.P.E.V. EG 513) there is no lettering or numbering showing the end type or direction. I have stored the drawings of the other variants from the time when Fine Models presented them (I found them again, see [12] at “E71 Painting- and Letteringlayout”). Var. 2 to Var. 6 have a ‘H’ and ‘V’ on the locos, which I assume is “Hinten” (rear) and “Vorne” (front). The Var. 7 loco has ‘2’ and ‘1’ on it. On my loco, Var. 1, the drawing shows “END 2” and “END 1” beside the loco, not on it. But the User Manual says that functions “F8 = Panto FS2” and “F7 = Panto FS1” which would show the end type when you actuate them.

The arrows are the left and right indications on my Märklin Mobile Station 2 (MS2). Observe that the side of the red conductor has a meaning when that roof is placed correctly towards the insulators of the pantographs. There is a knife switch in each end.

Loco meditation at low speed

I tried to run both the Märklin 55681 SBB Ce 6/8 III and the Fine Models’ E71 locos at the lowest possible speed. I have a Märklin Mobile Station 2 (MM2), using the first step there. I assume that’s the lowest possible step sent to the loco. I ran them from end to end on my 224:[layout MSRS v.4.1] – this is 199.1 cm buffer to buffer. Observe the elevation of 8 mm from left to right. For this test I had no sound.

The 55681 runs 199.1 – length 62.5 = 136.6 cm. It used 70 seconds in both directions. The drive mechanism and the regulator’s pulsing added no extra noise.

The E71 runs 199.1 cm – length 36.25 cm = 162.85 cm. It used 222 seconds running in direction 1 (uphill) and a longer time of 270 seconds in direction 2 (downhill). If I lifted the loco off the rail and placed it in the opposite direction, then there were the same running time and time difference for uphill vs. downhill. In other words, when the motors needed to deliver more power (uphill) it ran faster than going downhill. This is the opposite of what I expected. If I try a black box reasoning here (since I don’t know how the regulator is working) then: might this be called undershoot (PID regulator may give overshoot (here)..)?

The E71’s drive mechanism makes quite some noise due to the pulsing of the motors’ regulator when running uphill. At first I thought this somewhat surprising, maybe even somewhat annoying, but once I’ve got used to it then these meditative moments aren’t ruined at all! I have now ran it several times with my stopwatch app. Yes, it is meditative!

Some facts about the model

From the German Wikipedia article Preußische EG 511 bis EG 537. Find Ten Differences? (I had to download it for scaling reasons: source: Wikipedia Commons, here)

  • This model is made in Korea, for Fine Models GmbH. Source [11]
  • This model came into Fine Models GmbH [2] through Kiss-Modellbahnen Deutschland [9] when Kiss went insolvent in March 2020. Another part of Kiss became Kiss-Modellbahnen Schweiz GmbH [10]. Source [13]
  • Seven variants were produced. Summing up all the variants then 300 units were produced [11]
  • Length buffer to buffer 36.25 cm. Weight 3.0 kg. Smallest radius R = 1.02 m
  • I have some quite interesting Q&A going on with Fine Models / Kiss, see chapter External (below)

Fig.9 – The E71 with striped background

With the My Shelf’s Railway Strip (MSRS) v4.2 I made a new background from some fabric. See 201:[MSRS v.4.2]. I think it quite successful, look and feel wise. Photo wise, I may need some time before I get used to it. I guess that the stripes mask the catenary wires. Or maybe this effect instead draws attention to the locomotive?

Aside: I pulled the fabric behind the shelf and down to make it smooth. This is possible since the whole shelf is stiff enough to be hanging by the short ends only. It’s actually two shelves that are firmly connected, the lower is used for the Märklin Mobile Station 2 (MS2) plus flat books and magazines. However, the black aluminium column at the middle certainly helps holding the shelf, used to make sure any grandchild’s weight won’t end the locos’ lives on the coach below. You can see the column in the picture. The fabric is hanging in a 6*20 mm wooden list in a fold of the fabric. I had to splice about 10 cm at the end and then iron it flat. I used the sixties’ really lovely Husqvarna CL21A sowing machine for the project. My late mother in law, Aase enjoyed this machine before Mari inherited it. They both have kept it well oiled and serviced.

DB E 71 13 from Fine Models by Friedhelm Weidelich (18.8.2021). Read at https://www.spur1info.com/en/newsreader/db-e-71-13-from-fine-models.html. Quite an interesting read, with 57 very well done photos. Even if this is not about my model, but the Fine Models’ Var.7,  I assume that most of the comments would be correct. Like, the lights and lantern bulbs are simulated and made from round LEDs. This article also mentions the competitors, without naming them. But I spur1.at would at least be one of them (see https://www.spur-1.at/e-71 and 201:[My krokis notes]).

Weidelich complaints that the air ventilation openings “are are attached and not pressed as on the competitor’ s model”. At least in the open article there is no picture to show what he means. However – see Wikipedia Preußische EG 511 bis EG 537 from “Die restaurierte E 71 19 im Bahnpark Augsburg (2007)” which would certainly show the ventilation frames as being on the outside. But this may just not be Weidelich’s point.

Did she really exist? by Gastautor (16.12.2021). “For some railroad models, the question arises for a variety of reasons whether there was a prototype. Bruno Waldmeier has given some thought to this.” Read more … paid login at https://www.spur1info.com/en/news-archive/tag/Fine%20Models.html.
