(LGB) 25554 - reporting from the wild side

 This is a story straight from Klaus' workshop

Tom calls and starts ranting:" I have an (^***&#)-  engine here that runs only for 3 feet and then stops. For no obvious reason. It doesn't display headlights and the sound is not working". 

 Klaus asks:" What type of engine is it?"

Tom:" (LGB) 25554- the green one"

Klaus now asks Tom what kind of power supply he is using (standard analog 5 Amp). This excluded a motor going bad which would have overpowered a starter set throttle. As Tom didn't want to mess with it he shipped the engine to Klaus.

(LGB) 25554 by Maerklin/Simba-Dickie

                                                                                                  

The engine arrived three days later and was put on the bench right away. With the engine on its side Klaus connected regular DC power to the power shoes of the front motor block. Then, gradually, he raised the voltage having a close eye on the Amperage. Only to discover that the engine did not pick up any power on the front motor block. The same test on the rear motor block revealed a strange behavior:

Klaus' precision testing device - the voltage generator

the wheels were turning and when the voltage was raised above 4 Volts the Amperage would shoot beyond 4 Amps. Klaus immediately stopped the test to prevent further damage to the engine. Now Klaus opened up the engine to find a strange configuration of electronics in the rear body.

There was a soundboard (MTS) mounted to the base plate held by only one screw and an MTS onboard decoder mounted to a lead weight. Turned out it was the lead weight of a Forney. Now, this was something special.

Klaus has never seen a White Pass & Yukon engine with this kind of interior. The suspicion arose that this is an engine made in China. Another hint was the cover of the engine's switches and volume control: normally it takes a bit of an effort to remove the cover but this cover nearly fell into his lap. Which points to a different kind of plastic that LGB used in Germany.

Meanwhile a bit of research revealed that the engine was made somewhere in 2010 by Maerklin possibly while the takeover by Simba-Dickie took place. That meant China was still a possible manufacturing place before Simba-Dickie turned to open up Gyor/Hungary.

Back at the workshop the next step was to isolate those motor blocks and test them individually with regular DC without having the internal electronics of the locomotive connected. The front motor block did not pick up any power and only the motor worked. The rear motor block picked up power with the motor being OK but the motor would even run when power was only supplied to the power shoes. As this was a DCC motor block track power and motor leads should have been totally isolated from each other. So question was why did the motor run with power supplied to the power shoes? There was only one solution: a massive short between the motor leads and track power pick-up.

Opening up the lower lid of the rear motor block revealed two dislocated power bus bars. The bus bars were made out of sheet metal which was about half the thickness as the regular LGB bars would be. So it was possible that the lower lid was closed with the power bars dislocated and nobody noticing it. The imprints in the bus bars that were made by the lid and the body of the motor block confirmed this theory. With the lower lid screws being untouched it was clear that this happened in the factory. Unfortunately it also proved that there was no quality control performed in the factory.
Basically the same condition was found in the front motor block.

Klaus repaired the motor blocks and inspected the onboard decoder which turned out to be fried and

the yellow line circles the burnt decoder part

was replaced as well. Klaus programmed a new onboard decoder to match the locomotive and reassembled the engine.

After a quick test drive in DCC and regular DC the 'patient' was released as healed and shipped back to Tom - working just fine.

LGB Firebox Light - A Klaus Creation Part 2

The light bulbs of the choice had to be the 5 Volt plug-in bulbs which Klaus colored manually. The reflector was initially a piece of aluminum foil. Peter Stock, a close friend of Klaus since childhood times, designed the electronics. Klaus then cut open the firebox door of the LGB Mogul to insert the firebox-light parts and everything was implemented in a pre-production 2019 Mogul body.

The initial pause between firebox activation was 45 seconds long. So everybody kept watching the locomotive closely until the firebox lit up again. Surprisingly the light even illuminated parts of the track between the loco and the tender just as in reality. Later in production the pause was reduced to about 8 seconds.                                                                                                               

Old LGB factory in Nuremberg

Klaus demonstrated this locomotive and firebox to Wolfgang Richter and Gunter Ruhland in Nuremberg. Everybody was surprised and exited about this idea. They wanted to implement this product into the Mogul and Klaus was asked to finalize the product for mass production; namely design a reflector which can be utilized in the final product.

Klaus made several molds out of Dental Silicone - see below - to produce multiple reflectors of the same shape which then can be manually altered. The reflectors themselves were made of Dental Plaster. That way Klaus was able to alter the reflector surface manually to find out which surface works the best.

Note the 2nd piece from above: Klaus grinding bit surface - aka his "signature"

A couple of weeks later Klaus found out that tiny dents in the reflector made by a ball shaped grinding bit delivered the best results. LGB then had an electrode made according to this reflector and used this electrode to manufacture the injection mold for the reflector. This happened by way of the electrode being used in electro-discharge machining. This is the reason why the mass-produced reflector even still today shows the manual work of Klaus and his grinding bit - just like his signature.

Klaus firebox light parts before mass production

It became a huge success. After furnishing the Mogul with the firebox-light LGB installed it in other steam engines as well. All leading model train manufacturers picked up the idea and manufactured their own versions. A number of little electronic firms started offering those firebox lights in all their variations. Today it is a standard feature for pretty much all steam engine model trains regardless of scale.

Here is a brief video of Klaus original firebox light in a very old LGB Mogul:

LGB Firebox Light - A Klaus Creation

 One warm summer night in the mid 1980's Klaus was sitting on his back porch. 

He had just finalized the improvements for the first Mogul #2018D, namely the driving characteristics.

Now he was relaxing,  enjoying his LGB layout with an American freight train passing by. Led by a Mogul and trailed by a lighted caboose. After a while he noticed that watching the loco go by all he could actually see was the dominant headlight followed by dark ghost cars and the lighted caboose marking the end of the train.

Klaus had a clear sense that something was missing here.

There was a stoker standing in the front of the (Mogul) tender apparently doing something but he could neither see the engineer nor the stoker. Klaus assumed that the stoker was about to open the firebox door fixing to shoveling coal into the firebox. This must have some influence on the lighting situation in the cabin and front of the tender. The stoker must be standing right in the midst of this light. And that was it.

Now, how did he put this into reality? His first idea was to install 3 or 4 lights hidden somewhere in the rear part of the boiler shining through narrow tubes single light beams onto the stoker. The drawback of this idea was that when the engine passed by there could have been a chance that a bystander could look right into one of those lights. Basically, a good idea but not close enough to reality.

This made Klaus realize that there is actually more to reality than initially hits the eye. In a real steam loco there is a light source (fire box) which illuminates the control cabin and the stoker and the front of the tender. This light source should not be kept a secret. The bitter truth is that the stoker opens the fire

box and is then showered in a flood of (fiery) light. This consequently led to the idea to have lights being reflected in the lower door half of the fire box door. The lights had to be one red and one orange to give a warm, realistic light. the lights had to flash in two frequencies that are not compatible to each other. The red one would do a slow pace while  the yellow one worked a faster pace. The firebox light was supposed to jump into action every 90 seconds.

To install the firebox light Klaus would have to remove the lower half of the firebox door in the rear boiler part of the Mogul. Behind the still closed upper half firebox door the lights could hide. The light would be reflected by a reflector behind the lower open firebox door. This would even give the impression of embers glowing.

A smart electronic board would control the light bulbs.

He had it all worked out - in theory. Now he had to translate all into reality: finding the fitting light, creating the needed electronic board, cutting the Mogul open (again...)

Motor Trouble - Symptoms and Remedy

Worn-out Buehler LGB engine motors 

LGB uses Buehler motors in their locomotives and engine. Buehler motors are designed to work flawlessly in LGB engines and have an average lifespan of 800 - 1200 hours of loco runtime.

Depending on the type of the LGB loco the transmission of power works in two ways:

Either as direct transmission from the worm gear to a plastic gear wheel which is located on the axle of an engine e.g. Stainz.
Or: from the worm gear via an idler gear onto the gear wheel on the axle e.g. Mogul

Wear and Tear - Damage
Years of operation affect mainly the gear wheel- connected directly to the worm drive- wearing it out. Damage may also occur due to mechanical stress or load e.g. the train is running unmonitored, derails partly and gets stuck somewhere along the track and keeps running in that stuck condition. 
Or, your 2-year old son or grandson grabs the locomotive in full motion. This delivers too much power to the gear wheel as the gear wheel is forcibly stopped and the motor tries to keep running due to the electrical power supplied to the motor and the inertia of the motor. So the teeth on the gear wheel partly break off. This leads to an uneven and un-synchronized movement of the two powered axles of the locomotive. In  engines with connecting rods this will lead eventually to a blockage of the drive train.

Sometimes people notice that the loco runs significantly slower than usual with a decreased pulling power. Or the engine stops frequently. In this case the motor itself is giving up and pulling excessive amperage. In case the user is operating with a starter kit transformer this transformer will reach the end of its performance and shut down for cooling. When a motor is giving up it regularly transforms the energy supplied into heat which will be transported via the motor axle to the worm drive. The heated worm drive will eventually destroy/melt the  gear wheel connected to it. That ends the transmission of power. And the motor stops running.

The very early design of the Buehler motor provided exchangeable carbon brushes. One could visually check on the wear of those brushes by how far they were worn out. The later design is fully enclosed and therefor it is impossible to check on the wear. Buehler found out that when the brushes are worn out so are the bearings. So basically it did not make any sense to exchange the brushes. Nowadays the whole motor is being exchanged.

Motor Exchanges

Brand new LGB Buehler motors. Top: long shaft motor. Bottom: short shaft motor

TrainCraft by Klaus carries all required LGB types of Buehler motors. Klaus exchanges/ installs them in ALL types of LGB engines.

Make sure to use proper tools and fitting screwdrivers. The tiny LGB screws are easily damaged when operated with general household tools. Be sure to use the correct gear wheels depending on your loco type. LGB uses more than 9 different gear wheels. Some may look similar but beware of the thread and spacing.

Caution
The first generation motorblock was made of two shells (left hand, right hand) which are very difficult to service. You will find them in the early Stainz locomotives , the 2080's  Tank Steam loco (Brockenbahn) and the Crocodile (LGB 2040).

DIY on first generation LGB locos ... 
First you have to remove all connecting rods to free the wheels. Then you have to carefully remove the wheels and watch the spring loaded carbon brushes (the old type) which consist of a separate spring and carbon brush. If you're not careful the spring with the carbon brush would jump off and away. 

After all the wheels on that side of the motorblock which shows the screw heads have been removed  you can unscrew these screws and pull the two shells apart. TIP: put all screws in a bin or saucer to avoid loosing any.

When removing the motor one has to watch two tiny steel balls at the end of the motor axles. The early Buehler motors did not have thrust-bearings so these steel balls were necessary to keep the motor axles from moving sideways.

Installing the new motor
Make sure to have those steel balls reinstalled with a new motor unless you install a later generation Buehler motor which has load bearings.
Now comes the tricky part:
When re-inserting the motor you need to make sure that both loco axles are synchronized in their position. If you don't do it now you will not be able to correct this mistake once the motor block is re-assembled. The end of the loco axles provide two beveled portions which position the wheels. The synchronization can be easily achieved visually by assuring the parallel position of the bevels of both axles.
Be careful when reinstalling the wheels because the spring loaded carbon brushes have to come in first.

Best Bet: call Klaus and have him install your new motor along with all added/ required parts

Fun Fact: Buehler started in 1855 as a clock manufacturer in the Black Forest region of Germany. In 1892 the great grandfather of the current owners bought the company and added drive engineering to the production line. He kept the name Buehler for the factory and product lines. By 1955 the factory was moved to Nuremberg and the first electric motor was manufactured. Buehler grew from a small business manufacturer to a worldwide company with 1600 employees worldwide, manufacturing in 5 countries (USA, China, Germany, Check Republic, Mexico) and for the automotive, space, industrial and aviation industry.

LGBchen and Chloe - Conclusion

The LGB  Chloe and Olomana type loco 0-4-2(T) saw their last appearance with the 1998 catalogs. After that LGB would revert back to the O & K industrial field loco 0-4-0. In 2000 they published a (hand model?) 22140 in the 2000 catalog which made it to market about a year later

She made her market debut before the euro-conversion and was priced at DM 419.00 which later translated into Euro 195.00. The US market would see a price of around US$ 199.00. 

In the original package the US version came with an engineer in black, and 2 little oil cans and an original German "UHU" glue tube. This "UHU" glue was an 'over-the-counter- glue with almost

commercial qualities that once it dried had excellent adhesive qualities. There was no american substitute. The two little oilcans got lost over time on many 22140. In the pic above the owner painted them silver, original LGB 'color' was black.

In 2003 as, dear reader you know by now, LGB was going down the hill the same loco was re-utilized by giving her a new label and number, "Henschel & Sohn, Kassel" # 3 and re-marketed as LGB 23140

After the original LGB closed shop and Maerklin/Simba-Dickie took over it wasn't until 2011 that another LGBchen type was marketed. As the OLD LGB had done before it was re-utilized in a starter set, this time the LGB 70410. In 2016 and 2017 the Olamana and the Grizzly Flat would see a 'come-back'. It was the old mold but the plastic and the workmanship was not the same as under the old LGB.

In the past YT translated quite a few articles by HJ Neumann who once ran the biggest LGB Club in Germany. He still writes his blog and in his opinion the new LGB product range especially in combination with the new pricing policy is another nail in the coffin of Wolfgang Richter. Be that as it may - fact is the quality - especially the plastic and color- of the OLD LGB models was outstanding.  Fact is also that today's market still sees veritable numbers of Old LGB models being offered in often first-class quality. 

Here are  20130 pics from 2 sources: Only Trains and liveauctions.com from approx 2017. See for yourself and compare:

The original Old LGB 20130 sported highly polished chromed push/connecting rods whereas the new Maerklin/LGB engine features matte rods, maybe silver painted; compare

LGB 23131 - Courtesy of lgb.com, price US$ 350.00 approx

HJ Neumann was right and you dear reader are in luck: Klaus is here and ready to help with all your OLD LGB needs (and some new, too....)

LGB Chloe and LGBchen - Part 2

 By 1995 the Chloe was manufactured and ready to be distributed:

The 1995 LGBoA flyer/brochure

advertised the Chloe prominently at first exclusively for the American market. A year later it was also offered to the German and European LGB customers. The ad already mentions the LGB 30430 Grizzly Flats cars that were offered at the same time but separately. The LGB 20130 listed for US$ 299.00 and the cars for US$ 59.00 each.

The complete package if purchased together would have looked like this:

Also advertised in the LGB NEWS 1995 was the LGBchen 20140 which portrayed the industrial field loco of the late 1800's and early 1900's:

They were listed at US$ 269.00 and currently go for about US$ 390.00

By 1999 LGBoA listed both engines as "about to be sold out".

When sales volume in 1996 signaled a good market acceptance for both little engines LGB set out to do them again in a slightly varied manner. Thus the molds were reused into the LGB 22130

and the LGB 21140

The Olomana was priced at US$ 280.00 and the LGB O & K (21140) at US$ 270.00. The Olomana is hard to find these days and should NOT be mistaken with the new Maerklin/Simba-Dickie 23130. They seem a look-alike but that's were it stops. Small but important quality differences (wheels, color, workmanship) prove the Old LGB the superior and more valuable loco. They came onto the market in 1998 both in USA and in Germany/Europe.

Another debut was the LGB 72560 where the 21130 featured prominently as the (Chloe) Christmas loco with "Santa Clause" on the loco label and two Chistmas decorated open passenger cars

This set was originally advertised in the 1997 LGBoA Info 97 and the set was available that Christmas.

Focus on the middle of the photo to find the "Chloe" Christmas set

It is extremely rare to find a complete set with box, tracks & documentation these days. Values are up. Klaus has had but one single loco from a complete set on his workbench since he began shop here in the USA. The motor in this Santa loco is probably about to give up since it has been in the loco since 1997 and the life span of an Chloe/LGBchen motor is about 7-10 years depending on the run time (at Christmas). Klaus does have the motors and does motor exchanges and maintenance service on all the Chloe/ LGBchen engines. Spare parts are rare. If you are in need of any parts, contact Klaus by email/phone and he will do what it takes to keep your (LGB) engines running!
