Introducing the 4-6-4 Emerald Baltic, the newest steam locomotive from Nacho Enterprises Railway System (NERS).
About this creation

The Emerald Baltic, a 4-6-4 Baltic/Hudson style steam locomotive, is the newest addition to the Emerald Night class of locomotives.



The front cowling was originally designed by Ernő Rakmányi on their Emerald Night mod, which I have had the pleasure of acquiring. It looks very slick.



The tender is the same as the original Emerald Night, except for the wheel setup. Instead of two trucks with a total of four axles, this has three axles since the Power Functions Train Motor has been added. The connecting wire is run to the IR Receiver that is located within the boiler. The cable from the IR Receiver is then run back to the Battery Box. An Extension Wire may be required to connect the motor to the receiver.



This MOC is very simple, really. All that was required was to take the firebox, cab, and pony truck from the original set and swap it with the same components from my 4-8-4 Emerald Northern. I think that it came out rather well.



Here is a look inside the cab. Since the motor is moved to the tender, as compared to the original Emerald Night set setup, the cab is clear for lots of play. There is also plenty of room for running the required wiring.



From Wikipedia about the 4-6-4 setup:
The 4-6-4 tender locomotive was first introduced in 1911 and throughout the 1920s to 1940s the wheel arrangement was widely used in North America and to a lesser extent in the rest of the world. The type combines the basic design principles of the 4-6-2 Pacific type with an improved boiler and larger firebox that necessitated additional support at the rear of the locomotive. In general, the available tractive effort differed little from that of the Pacific, but the steam-raising ability was increased, giving more power at speed. The 4-6-4 was best suited to high-speed running across flat terrain. Since the type has fewer driving wheels than carrying wheels, a smaller percentage of the locomotive's weight contributes to traction, compared to other types. Like the Pacific, it was well suited for high speed passenger trains, but for starting heavy freight trains and slogging on long sustained grades, more pairs of driving wheels are better.
To sum it up, the only advantage that the 4-6-4 has over the 4-6-2 is that higher speed and power across flat terrain. It still is an improvement, albeit a small one.



Here the Emerald Baltic is shown with its rake.



*Twitch's Remarks*
So this is just a small stopgap MOC while I finish up some minor details with the rest of my Classic Space Train sets. Plus, I have not produced a steam engine in a while, so I figured why not.
I chose to do a 4-6-4 for several reasons. First, I originally was going to make a 4-4-2 Emerald Atlantic, but the Atlantics were not able to pull as much as the 4-6-2 Pacifics. Therefore it would be a step backwards in terms of power and performance. Another design that I considered was a 4-4-4-4 duplex, but there was just WAY too much overhand in the front and the rear when in a turn. I thought about what was an upgrade to the 4-6-2, and realized that the 4-8-4 is really the pinnacle of non-duplex/mallet steam passenger locomotives due to the layout of the wheels. So I settled for just a minor upgrade over the 4-6-2 for now. I may do some further research into other passenger locomotive types and design another Emerald Night variant. For now I like to stick strictly with passenger locomotives since I am not that much of a freight steam locomotive fan. Besides, I already made a 2-8-2 Emerald Mikado, and I am not a huge fan of it. The Emerald Night does not work well as a freighter, and I like designing Emerald Night variants.

As always, please rate, comment, and enjoy!

Quoting Jim Kolk Think you can alsm make an Emerald Challenger?
Apologies for the late reply. As far as an Emerald Challenger (a 4-6-6-4 setup)goes, I have seen some that have been done over on flickr. While it may look great on straight track, my real issue is that there will be a LOT of overhang either in the front, rear, or both. I design my MOCs as if they were actual official sets, so I try to make them as playable as possible. Having that amount of overhang really takes away from the overall feel and look of the MOC. This is also why I have not done a Mallet/Duplex locomotive in a while.

Quoting cyberfrank 2010 nicely done! I can t wait to see your real one again though.
I am unsure if I will make this one in real bricks. At some point the new version of my 4-8-4 Emerald Northern will be made into real bricks.

Quoting David Roberts I like the opening firebox door, complete with flames in the firebox.
That is a feature of the original Emerald Night set that I include in all of my Emerald Night class of locomotives.

Quoting Hunter Dobbs Superb, simply superb. I like thew Hudson redesign, I've been working on a concept myself, but how does the redesign affect the gear train?
There is no gearing since it is tender-powered by a PF Train Motor. Thank you for the kind words.

Quoting Commander Cold How did I know you were going to do this! Its very nice. I like trains, but monorail will always set in my LEGO mind.
Get out of my head! It is already very crowded in here... We all have our own personal tastes. I like monorails, especially the Disney ones, but I will always be a sucker for steam trains.

Quoting Murdoch 17 Good job! i think the Gray color scheme looks nice, and the improved smoke deflectors look even better! (Though as you said, they are not your idea)
I agree, the gray does look nice, especially with the new front end. Other than red, now I need to decide what the next one's color will be.

They are going to be awesome, rest assured.
