Stadler FLIRT

[LEGO Train 12 Volts]

Hello everyone,

today I want to present my version of the Stadler FLIRT (Fast Light Innovative Regional Train), 6 studs wide, in Junakalusto's green and blue livery.

What I like about this train are the shared bogies and the clean, modern design, with ample space for both passengers, wheelchair users and cyclists.

The train, consisting of four carriages in total, is asymmetrical, because in the third carriage a window is blank due to the presence of the restroom.

It wasn't easy to reproduce the front silhouettes, so I used some technic elements with a double hinge and one degree of freedom.

As always with my trains, the convoy is equipped with lights, and the on/off switches are located in the respective carriages.

 

 

I wish everyone a Merry Christmas!

I've ridden these very trains many a time. Nice model!

I'm glad to hear this @TeddytheSpoon!

Nice one. Looks very much a like local Dutch trains. I like how you did the nose. I would have done a complete green brick between the lights though and not half like now.

Great to see that rear end also lit. Is that via the hub? Or a separate power source?

@LEGO Train 12 Volts: nice job in 6w 👍🏻

However, two things struck me when I looked at this picture:

Have you ever tried half or quarteri tiles instead of circular tiles? Mayve also in trans brown or trans black (not available from TLG)?

2. as @LL1982 already mentioned, I would either make the tile at the nose completely green or reverse the colour distribution (i.e. small white stripe).

Looks great... only thing I can think of is that you could use some wider radius curves for this train

Excellent model in 6-wide. Top quality video as well, that took some editing. Can you provide more details of the Powered Up motors hubs and lights please?

I did not knew that part came as trans, something to remember!

A Christmas gift from Emanuele!!!

And as per usual: Perfect. Really nice - 6 wide and an interior that would not even fit into 8-wide if I had made it (apart from so many other building techniques, I'll never master ...).

Have been on those as well.

Thank you very much for sharing, please say hello to the family (we're up North again).

Have a wonderful Christmas!!!

There are independent circuits and batteries for the two engines, each has its own on/off switch.

Regarding the lights, I agree with your observation, but the 6-stud format doesn't allow us to do any better. As for the front, you're right; it would have been better if it were more green or less white. I'll consider making a change.

I totally agree, the 40 radius curves are just for stress testing but the final circuit includes both 56 and 72 radius loops.

Your compliments about my trains are always appreciated, but what I love is how you go beyond that to something deeper and more substantial... so I reciprocate your good wishes (I would have bet you had gone north!)

It is really nice as 6-wide, and also give me some nice memories about starting my topic back in 2009 with my old Stadler FLIRT design.

As 6 wide train it has the advantages of a regular LEGO train set needing less space compared to an 8W MOC, but also has nice details which we miss from official trainsets.

I'd recommend is remove the LEGO train window glasses from the frames and replace them with single non-train window 1×4×3 glass as the real train have only very limited number of openable windows.

 

[LEGO Train 12 Volts]

I was wondering if I'd get your feedback @Ashi Valkoinen, as someone qualified to handle this type of train...and I thank you for your kind judgment.

The observation about the windows is absolutely true; I hadn't noticed that detail...it would have been cheaper, too!

[Ashi Valkoinen]

I am the man of honest opinions, everyone knowing me in person could tell you. :-)

I am not great fan of 6W since it looks odd on LEGO tracks (train just slightly wider than the tracks underneath), but I can accept that people make different choices when it comes for building so I try to add opinion judging the build itself and not the choices behind. For a 6W build, it looks proportional, the train is clean, no unnecessary fluff, gives back the vibe of the real thing well.

I don't know if anything could be done about the front (the FLIRTs' noses are narrowing, too, and the side windows of the cab is visible when you are standing exactly in front of the train), but making a narrowing front starting from 6W would destroy the well-built proportions and maybe the cleanness of the design.

So, as 6W, it is a great build, no mistakes made that can be seen at many 6w trains.

Personally I felt the same cleanness with the 2009 red PF passanger train (similar to german Siemens Desiro DMUs), except for the doors which LEGO forgot to put into the model. When parents asks me about building traisn at different shows, I always show them that set, teaches more to the kids compared to the trains with front cones of one mold.

Safe the train glasses for later, those are getting rare, they will be great for an another build, like a traditional coach.
