And now with new rods from zephyr1934:

Sorry, I forgot the 11,1V Li-Po battery which gives power to the smoke generator. It is placed in the wagon right above the motor and weights 100 g.

Thanks everybody! No extra weight. Though, the LokSound decoder and speaker are placed in the tender, but they don't apply much extra weight. Yes, as I wrote in the Is It Worth Buying an Emerald Night Now? thread: Do the mods described in RailBricks and the forum, and turn the engine into a push-along train. Then, place a 9V or PF motor under the wagon. With PF, always place the battery box straight above the motor. The load regulation (usually called back EMF) provided by the DCC decoder makes it possible to run smooth with only one 9V motor. With regular lego 9V motor control, you will probably need two motors to pull the train. Though, this train doesn't like S-curves and steep slopes. Not really. I made my first lego steamer with sound in 2003, and Matija introduced smoke generator in his Blue Train in 2008.

If you are looking for a lego steam train, Emerald Night is the one! Take a look at my train. I just uploaded a new video in my MOD: Emerald Night thread. Do the mods described in RailBricks and the forum, and turn the engine into a push-along train. Then, place a 9V or PF motor under the wagon. With PF, always place the battery box straight above the motor. Well, definitely British. It is quite obvious that Emerald Night is based on the British engine, Flying Scotsman:

Here is a new video of my Emerald Night: The train runs around my train layout at the LEGO Norway 50 years anniversary event in November. The video is shot by shutinc.

When I am not playing with trains, I build robots. Here is my current project... The base I found at nxtprograms.com. It is programmed in NXC and not very presise. I need to explore the new motor control functions to make it more accurate. I'm also working on a more advanced gripper.

I would like to see a part like the old Train Steam Drive Rod Holder, but with an axle hole.

Cool project. Looking forward to see the progress, and I'm interested in the research regarding tracks.

The train is made by Bjørn-Erik Gunnerød some years ago: http://www.mocpages.com/moc.php/33356 Very nice models, both the station and the train.

Bumping this thread with a new video shot by Eiker86. :)

Great! I have had this idea for years, but never got the time to implement it. Guess I will buy some of these rods. I currently use rods made from an ice cream box.

Cool. Can you tell more about it? What is the track voltage you use? How many amps at the track? And what kind of decoders do you use in the trains?

Yes, thanks. You find all the info there. It is standard model railway stuff. I'm actually surprised that LDCC is not mentioned in the Eurobricks forums before. I tried to search now, and my posting is the only one. I have no clue about the cost. The train base plates are switched to black and extended by 2x6 plates like the Santa Fe wagons. The bogies are a little bit modified.

This is a kind of magic... ...and probably not healthy.

Well, if you are not familiar with LDCC, read Mark Riley's page about it. I use the 1.05 beta version. Also read Tom Cook's page on DCC. He describes how to open the motor and install a DCC decoder, but instead of a small decoder you apply a female 8 pin NEM 652 contact as the LokSound decoder and speaker are way to big to fit inside the motor. The LokSound decoder works OK with 9V. Though, you might have trouble with some sounds and things like playing driving sound and whistle simultaneously, but no problem finding projects with sounds that work fine. I guess it is possible to use some other digital command station for model railways, but they usually run at a higher voltage. It might be possible to configure the LokSound decoder to work with the analog 9V speed regulator, but I haven't bothered to try. Digital control is much better. You can run your trains nice and smooth even at low speeds. As said in my first post... It is powered by an RCX running LDCC. This requires 9V train motor and tracks + the RCX remote control. The 9V train power adaptor fits straight into the RCX 1.0. Not possible to run this using only batteries.

Behind the scene:

Thanks. The "layout" is just a small scene put together just for the photo and video shooting of this model. Though, I'm working on a new big layout in the same style. Music: Onkel Tuka - "På den andre siden av fjorden" ("On the other side of the fjord"). I have two other engines with sound and smoke, one is an Emerald Night mod. Plenty of space in large engines, thus the EN solution is a little bit different. A larger smoke generator, Seuthe nr 6, is powered by a 11,1V Li-Po battery. EN also have six mini magnets and a reedswitch to sync the sound with the wheels. Guess I have to get some images and make another tread. BTW: A newbie question... How does this 100k upload quota limitation work? Is it pr day or week or anything? Or have I spent my EB upload quota for ever?

Model of Norwegian steam engine NSB type 7a number 11. Equipped with a LokSound v4 decoder, some warm white LEDs and a Seuthe nr 99 smoke generator. To get some more juice an AnyVolt Micro is used to lift the voltage from 9V to 11,5V for the smoke generator. All powered and controlled by an RCX 1.0 with LDCC firmware. The original was built in UK in 1892, worked as shunting engine in Oslo, outranged in 1964 and restored during the 1980s. Currently at the railway museum, Krøderbanen.

Anyone who knows what happend to nxtasy.org?
