Hello,

Some months ago I posted my Power Functions High Speed Train with automatic doors. Although the door opening technique was novel, it wasn't very realistic and the construction didn't allow for train interior.

So I set out to make an even better door opening mechanism and this is the result:



Did you notice the retracting stairs and the lights flashing when the doors were closing?

Below are all the details about the train, see all the pictures in my Brickshelf folder.



The train makes use of Power Functions to control the following features:

• Train speed (adjustable)
  
• 3 front lights and light in the driver's cabin (adjustable)
  
• Sliding doors, retracting stairs and lights (on/off)
  
• Interior light in cabin (on/off)

Train front

The train front is mostly SNOT and has three working PF head lights. I thought I might as well use the last light for interior light in the driver's cabin. See this picture for a cut away view of the consruction of the front.




Sliding doors

The mechanism for the sliding doors is hidden below the center car allowing for full interior. It uses the 9V micro motor, some gearing and liftarms. The lights above the doors use an old 9V light and shine constantly when the doors open and flash when the doors close. The retracting stairs... well, see the video and the pictures, it's pretty hard to explain.










Interior light

Well, I had one IR channel left, so I added some interior light in one of the cabins:




Front cars

One car is stuffed with Power Functions gear: 1 rechargeable battery box, 2 infrared receivers, 3 PF light cables (= 6 lights), 2 PF->9V cables and 3 9V cables.
The other one has a standard passenger train interior.




I think that was it. I really look forward to your comments.

Very impressive! I just love how you even managed to make the stairs come out, and all of this was contained within a 6-wide train. Great job!

[roamingstudio]

Wow.
Wow.
Erm.
Wow.

Great idea.... for the doors especially.

[Melfice]

That's just amazing.
Simply amazing.

It's a shame you couldn't get the doors working on both sides of the train, though. But considering the mechanism used, fully understandable. (Also, more than I could do. Again, simply amazing!)

The technical aspects of your design make this creation very unique and special. So often it seems like a lot of aesthetic design elements have to be sacrificed when incorporating so many power functions but you have designed a train that seems very real with a very comfortable minifigure scale. Great job!

OMG!!!

I'm speechless, the ingenuity of this MOC is ..... beyond reason. I've been looking at this for some time now and still am puzzled by some of the aspects of the build.

Both the new and old version of your automatic doors are outstanding, I'm not much of a train fan but this is at the top of my favorite techniques/builds!!!!!!

Thanks for sharing the technique too, it's most appreciated.

Now If I could only find my jaw .... it dropped earlier!

I totally agree with you, Piratedave84. MOCs like this one make me really happy to have discovered Eurobricks. The retracting stairs are especially awesome.

By the way, might I suggest checking the floor for your jaw? That's where I found mine.

one word:

AMAZING!

[Marko]

wow wow wow I rarely visit Train section and even less Technic section but always when I do I understand that LEGO is not only a toy but serious engineering tool

Excellent detailing, specially the mechanisms.

Thanks or sharing.

[lightningtiger]

Just what do we say really to sheer genius...........AWESOME..............FANTASTIC..........PERFECT !
The lighting system and that dam awesome mechanical door system - man, that is so COOL !
The bar has been raised - 'The Brickster' needs to FP it !
Keep on bricking 'Esben Kolind' really keep on bricking !

[Kenneth]

AWESOME!

I wouldn't have believed it was possible without video!! Thanks for sharing the design details!! I wish I had the skills and pieces to replicate it.

[dr_spock]

Awesome work! Super cool.

[Marin Stipković]

Amazing system for the doors. I also like all of the train's functions. That picture taken in the dark is extra good.

[Duq]

Awesome work Esben! The way the doors push out the steps is sheer genius!
I'd say both your PF trains make a strong case for Lego to do a PF micro motor

[Ras 74]

That is probably one of the coolest features I have ever seen in a LEGO model
Deeply impressed. The whole train is a great creation as a matter of fact.
