I have been a fan for a long time of the Austrian U class and its related subclasses. I have some models of these locos in various scales.

After finding a post made a while back on the LGB Club’s board I decided to do some research on the different versions in my collection made and by LGB and Lilliput (H0e scale). I have detailed the LGB ones here.

LGB made this loco in a few different versions. Initially, there were four. In my notes (LGB) appears by the version that LGB modeled if there were different owners. The basis of the frirst four versions are as follows:

2070/D was Krauss-Linz 6824, built in 1913, kkStB then StLB U43 (LGB). Done in black and grey. Prototype is in disrepair, fractured cylinder block? Grey version done on the 75th birthday of the loco by LGB for 1988. Model built 1971-1974, with 2070D 1974-1978, and again 1987-1990 (grey).

http://www.stlb.at/triebfahrzeuge/details/u43.htm

2071/D was Krauss-Linz 4506, built in 1900, Zillertalbahn #2 Black,(LGB) some with stripes in red, others not. LGB have done many versions. Prototype is in service. Model built 1971, with 2071D 1972-1989, replaced by 2171D (see below).

http://www.railfaneurope.net/pix/at/privat...am/2a-zbahn.jpg

2072/D was Krauss-Linz 3711, built in 1898. NÖLB U3, BBÖ, DRB 99 7819, ÖBB 298.53 (LGB). Similar too the early 2071/D and gained LGB's taller cab roof. ÖBB 298.53 is currently in service. Model built 1971-1973, with 2072D 1973-1978, Primus version sold also.

2073/D was Krauss-Linz 3816, built in 1898. kkStB U14 , CSD U37.004, DRB 99 7843, ÖBB 298.14, then Eurovapor 298.14 (LGB) The loco left the Waldenburgerbahn in Switzerland in 1984 and went to Germany. It is currently on the Öchsle Bahn museum line. There it was under its ÖBB number of 298.14 until 1994, then put under its occupation number of 99 7843. It is privately owned and is in a state of disrepair. Model built 1973-1974 with 2073D 1973-1987.

MODEL NOTE: 2071D (now 2171D) and 2070D got the newer power block around 1988. Identification are the power skates, plastic valve gear, constant lighting w/gold light trim, smoke, and internal switch.

With this, 2073D becomes an enigma. The Kalmbach LGB guide lists it as going out of production in 1987 (ties with block change above), but the catalogs show it until 1990 as a Discontinued Item. Did this retain the older style motorblock until its end of production with the sale of remaining stock until the end?

Of the four above, from what I can tell, the basic body shell of the 2071D/2073D were continued for several versions including:

LGB 21711 was another Zillertal #2 offering, renumbering of 2171D in 1993.

21701 was Krauss-Linz 4183, built in 1899. FOD 11, CSD U 37.007, DRB 99 791 and then DR 99 4712 (LGB). Prototype broken after a 1959 wreck in the 1960s. Of interest, this was one of three U class that were not to Bosnian 30 inch gauge, but Saxon 30 inch gauge. The difference beeing 750mm in Saxony, while the Bosnian (and all of Austria) were 760mm.

Photo online? (I have some before and after the wreck in print here in books in DR paint, and it appeared in LGB's 1993/4 catalog also).

LGB 20705 "Raimond", it turns out, is Zillertalbahn Nr. 1. or Krauss-Linz 4505 of 1900, one lok ahead by production number of Zillertal Nr. 2 (Zillerthal). Other than a brief stint under Austrian military "ownership" during WWI (which I have neglected on the master list for a few other loks)has remained as ZB Raimond Nr.1 all its life.

Came as a set only: http://www.lokshop.de/images/Lgb2000/20705.JPG This is the only LGB U to come with factory sound as of 2006.

20721 was Florisdorf 1354, built in 1900. NÖLB U6, BBÖ U56, DRB 99 7822, ÖBB 298.56 (LGB). Prototype is in service. The only non-Kraus built model by LGB, but why have the left off others?

(NOTE: General U info provided, Kr-Li data not for Fl built lok).

23701 was Krauss-Linz 3709, built in 1898, NÖLB U1. BBÖ U51. DRB 99 7817, ÖBB 298.51, and then preserved as NÖLB U1 again in a VERY light pastel greeen (LGB has strait stack, photos of the preserved loco shows strait and turban stack in the late 1980s). Prototype in service.

http://www.railfaneurope.net/pix/at/narrow...9851rupph01.jpg

2171D/22711 Zillertal #2 being a staple. Details above. Version with sound in a limited edition set.

The 2070/D shell comes back once again for:

22701 U43 coming back with the low cab and bunker in black with a shield on the front, detailed above.

An interesting item to note on the LGB models is the lack of working lights on the smokebox, even those that had such lights they were “blanked off”. Some of the versions that were modelled by LGB should not have front tank lights, as shown in the photos.

LGB also dorked with the cab roof heights. This was done, supposedly, due to the cab roofs not matching the other cars. A shame, as the prototypes do not and it makes the later loks a bit top-heavy.

What is left?

CSD (Czech)

PKP (Poland)

JDZ (Yugoslvian)

MAV (Hungarian)

DRB (German Occupation)

…And with some bashing (smokebox/tank mods we could see the SKGLB and CFR (Romanian, one of these is in the US now, shown below) versions.

http://www.steamlocomotive.com/misc/images/cfr395104.jpg

Also on LGB models as on prototype:

Turban and stovepipe stacks were both employed.

Spoked and disc drivers (like those on the “Stainz”) were used depending on date and builder on the prototypes. LGB reportedly used these on the earliest of versions.

Measurements. I finally got a chance to measure one of these and compare them to publshed KrLi drawings from Club 760. I have the prototype dimension and the model "scaled out" by taking the model and x 22.5:

Rear buffer beam (not buffer) to rear trailing wheel: 1150mm/Model 1102mm

Trailing wheel to rear driver: Prototype 1900mm/Model 1777mm

Rear driver to center driver: Prtotype 900/Model 990mm

Front driver to center driver: Prototype 1200mm/Model 1215mm

Front driver to front of smokebox: 1530mm/Model 1507mm (1400mm on some loks in prototype)

Buffer to buffer (U43), with rear bunker: 7640mm/Model 7650mm over LGB buffers/couplers.

Unfortunately, no height dimensions given.
 
ive a question

all of my lgb engines with a cab switch have 0-1-2-(3) typically toward the driver for 'on'

i own but a single zillertall loco

my 21711 is the opposite and unique among all of my LGB in the travel direction of the switch-
was this assembly abberation at the factory or typcial for these ?
 
Heres a grey early one or two?
 
And a Black #2 with high roof.
 
In case anybody was wondering about the reference to high and low cabs it's this.

I must say I prefere the lower roof line myself..........

Do all u class have switch? Can't find one on mine.

No. The split box ones do not, the clam ones do, like most/many of the other lgb locos of similar construction/design.
 
there are differnt types off gearboxes on lgb loco, as lgb progressed they delovoped better, easyer to maintain gearboxes, the clam type was 1 off the 1st, it was split stright down the middle, but this ment you had to revove the wheels, valve gear to replasce the motor, or fix it.. lgb moved on to the clam (like a clam sheall) was the next improvement, ,looks likea sandwitch, had a removeable lide, lgb brought out the "D" type gear boxs, which is its latest, and easeyest to work on, it has 4 pins, sticking through the top, enabling wireing modifications(digical) to be made easyer :) there are others, differnt viariantions, stop gaps, in between,
 
U37....kept its number all its life in what is now Slovenia. I have photos of it in service here in a book at home.

What is funny is the Czechs classed all their U's as U37.xxx. U = narrow gauge, 3 = drive axel count, 7 = weight per axel, then the actual loco number, 001, 002..... So a Czech U37 is not U37 in the Austrian sense!

As for the LGB grey U43, I am thinking it is a "Fotoanstrich" (builder's photo) scheme, like most grey model locos? An oddity that some like to model, and a few preserved locos have been painted to duplicate.

Example here: http://de.wikipedia.org/w/index.php?title=Datei:NoELB_3.jpg&filetimestamp=20060527203305

See the note on "werksfoto".

As a recent newcomer and a bit of a U-tank geek in the last month I thought it worth posting this from the 'My first Zillertalbahn 0-6-2' thread...

Unfortunately, LGB dorked with the cab heights. From 1978-ish on, the odd number units have a unfitting and TALL cab. The 2070D kept the low cab.

I had a 2171D that I sold off in a couple months, the cab height drove me nuts....

But then Andy (MZB) pointed out, there *may* be a prototype for such things!

Also note the JHMD hacked one tank for the air brakes, and the removal of the brake ejector....

Just to show there is a prototype for everything!

Since my 2009 post.....sheesh.....I have acquired a second 0-6-2,

2070D a grey murtalbahn U43...but, may be a 20701, but my box indicates 2070D, and its original.....

note, it has pick up skates, 5v lighting, and, head light lens and gold surrounds, low cab, and integrated grey electrical rear socket plug, (not the black plastic insert of the earlier version) , smokes prolifically and has the plastic valve gear (which is far more delicate than I ever knew, especially those top exhaust pistons.....I added the blanked out light , as the model does not come with one. I have had to repair the little piston shaft.... I guess they can come out and catch and then break...pretty sure I bought it in this condition, but failed to notice it until a day or so later....

I have seen these in grey and always pay attention on ebay, as I kinda like them, but, these second or late versions are, in my observations, somewhat rare, compared to the earlier version without 5v electronics and bare yellow bulbs in the light housings.

I think LGB changed their numbering scheme in the 80's or 90's to leave out the D suffix (for dampf / steam) and replace it with a 5th digit, usually a 1, hence 2070D and 20701

Thanks for the update Andrew. I assume you have one!

Yes, and a few of its friends from the list.


Just to add the green 2073 has a few variants under the same name as well.

original 2073 plain green none smoke, low cab, plastic trailing wheels, old type coupling (yellow lgb box)

2073 added “D” plain green, smoke, low cab, plastic trailing wheels old type coupling (yellow lgb box) red circular D sticker added. (factory modification to the last run of locos)

New 2073D green yellow pin striping, smoke high cab, metal trailing wheels, new coupling (replaceable springs as per current design) (red lgb box)
 
I’ve just acquired a used 20721 and haven’t been able to date it. Copyright date on manual suggests 2003 but it wasn’t in the 2004 catalogue so it obviously came and went fairly quickly?
 
According to LOK and LGB Kompendium it came out in 2003 and LGB Kompendium says it was still available in 2004.
