there's a new little locomotive in town and this time it is a 1:22,5 scale for real

Show it!!!!!

Coming in a few minutes

I have to admit, XXL doors are my problem , but I'm working on them. This is the 7710XXL , featuring a protoype of the new low-profile locomotive chassis with two L-motors (prepared after @Tenderlok suggestion). Its blue and yellow cars, plus an optional red-blue livery one, are used to experiment a bit possible solutions (also for coupling - currently not showed).I

One very simple solution for XXL doors and windows is to make them smaller than the real doubled size (I'm at Lego Basic level - SNOT at minimum level) and to create a grey "metal" frame around them. But I like the windows look and not the doors one - the good side is I have all the internal space available for seats.

I missed this thread the first time around, but those are fantastic builds. Are you aware that Lego actually made an XXL door? Too bad it is only in black or white though.

Thanks for the suggestion!!! - I see these big doors are six stud large instead of 8 (for XXL trains I always double the dimensions). These are more proportioned and really are interesting!!!

Hi all, Id' like to show some projects I'm working on, just to understand what do you think about them.

The first one is the second Toy Train Locomotive, called "Stainz". It is the locomotive LGB uses for its starter sets. But it seems that LGB loco is not a reproduction of the real Stainz, but a very similar locomotive.

The two locomotives have very limited differences, but I wanted to use the real one as model. The Stainz "2" locomotive has one main difference against the LGB Locomotive...the two laterel reservoirs (one for the water and one for the coal), are longer, plus the coal one is higher than the one used for water.

It still needs a lot of work, especially on coupling rods and cabin. Boiler is heavily inspired to @Tenderlok locomotives, it is only thinner.

 

The other one is a FAUR LXD2 Diesel locomotive from Poland. This is a big amount of work and it's my first trial to create an heavier locomotive. There's a bit of SNOT in this one, to reproduce the original shape of the doors on nose and tail. Even if the Polish locomotive runs on 760mm track, FAUR produced also the metric gauge version.

This one is based on two PF L-Motors and a standard AA PF battery .

Both are built in 1:22,5 scale, starting from technical designs and photos.

 

Hope you like it!

Ciao! Davide

This is BRILLIANT!!!!

Would love to see them running on my layout...

Regarding the rods of the "Stainz", I will propose a solution how to build an alligator crosshead with double guides when I present my next model (hopefully in a few days). Perhaps you can use this solution, too.

How did you gear the Diesel locomotive's motors to the bogies?

I've been following the activities in this thread for a while, and these locomotives - in fact, everything in this thread - looks stunning. It's good that you found the real loco to use for the first one, it's always better to avoid building a model of a model! I hope you get to build them in bricks soon, they should look fantastic running.

Thanks!!! Actually I have the real LGB "Stainz" Locomotive, and I can say it's pretty correct regarding dimensions.  As a result, my locomotive has the same dimensions of the LGB model, more or less (wheels are a bit smaller). The first yellow Toy Train I made has the same dimensions as the LGB Stainz, since It is completely freelance. It was really a model of a model!

Thanks, Sven!

The bogies are attached to the main chassis using turntables, the vertical transmission axle is using the turntable's hole to reach the bogie. In this way I avoided using transmission axle both for turning bogies and moving wheels. The two motors are one inside the cabin and the other one inside the hood. This evening I'll make you some renderings of the open locomotive!

I received today the two L-Motors and a PuP Medium motor. Wheels will arrive in the next days, so the mockup of the LXD2 will be created!

Thanks for your offer on alligator crosshead!!! I will surely study it - My solution is too weak, and sincerely I do not like the cylinders at all!

Well, why wait...
Here's a sketch of my cylinder/crosshead solution:

It uses the old Technic connector 3651, whose studs fit in just between the two crosshead guides. The "Minifig Neck Bracket with Technic Pin" is to attach the valve gear's union link, but of course this can be omitted without affecting the crosshead's function.
The upper one of the red Technic cross axles goes deep into the cylinder and provides enough stability to hold the lower one as well. To understand this better, I uploaded the Stud.io file for the whole thing here.

I already thought it would be an arrangement like that. While it's neat and easy to build, in my opinion it has one major disadvantage: The bogies can't swivel freely when the motors are not running, at least not without at the same time turning the wheels. Because of that, I chose another solution for powered bogies, with the motors mounted vertically directly on the bogies:

This layout's drawback is of course that there must be plenty of space inside the locomotive body to allow the motor to turn with the bogie.

Nice solution!!!

I prepared a similar thing using the modern version of that connector - the one without studs - I'll try this one for sure!!!

Regarding bogies: yes, the drawback of the turntables solution is the one you mentioned, transmission affects free bogies turning.  Your solution is neat - I tried the vertical mounting too (directly on vertical axle) , but then...the problem was to attach the bogie to the chassis (but LGB cars gave me an idea).

The LXD2 has a narrow hood, plus the SNOT mounting of the sides requires some internal support structure, so I abandoned the vertical mounting solution.

A good thing would be to integrate the motors inside  the bogie, but I only could achieve this goal with the M Motor for the moment. L Motors are bigger and it's quite a mess to fit them all under the chassis and have all wheels driven at the same time.

One solution I tried without particular success is cardanic transmission (like railcars with diesel motors mounted under the chassis), but it's not so solid, especially on heavy models like these.

 

 

@Tenderlok

This is my proposal for the bogies with vertical motor:

 

In this case, motor is all-in one with the bogie. I have to try it in real life, but it should work (maybe also in smaller scales)

@Paperinik77pk That is pretty darn clever!!!

Im really liking the new engines!

Great job.

I like all your models, even if you work on a scale that is not familiar to me.
