MOCs of BR 9F (Evening Star) and BR 4T

[TomOOO]

Emmet would like to show of 2 new Engines in the Engine shed.

The first is BR Standard class 9F (Evening Star) in green livery.  This is the last of the steam trains built in the UK (hence the name) and although designated a freight (F), this class found itself a very capable passenger engine.  With a top speed of 90 mph and not needing a banking engine on inclines on the more difficult routes this is the largest steam train built in the UK.  And a favorite.  ( I hope these links from Pinterst work....)

Front view 

 

Notice the "flying boiler" design that is distinctive of this class

Side view

In the above you can see the 3 axle tender designed for this engine

The next picture is some detail of the underside with axle 4 of the 10 driving wheels driven by a medium motor.

 You can also see that the 3 axle tender uses a fixed single wheel plus 2 axle bogie.  This view also shows a pivoted rear coupling due to the long overhang, as the rotation is about the flanged 2nd and 4th driving axles.  The extra blanks come from Big-Ben bricks.

The next series are of Emmet showing us around the BR standard class 4T (tank) engine.  Note that this was never painted in green livery.

 

This MOC is rather tight on power function parts and it is all rather compact on the inside.  I notice in my pictures that the bricks need puhing back togther, but I was carting the engines around 

This is a side view

 

You can see the IR receiver in the coal bunker at the back, with the medium motor tucked just in front of that.  This drives the 1st axle via a gear reduction to give a nice smooth and controllable engine with a slow speed. 

Here is the underside of the engine.  It shows the 2-6-4 configuration of the wheels and that the 1st axle is driven as it was not possible to drive the rear axle due the compactness of the drive and fitting in the battery box in the boiler

In fact, 2 of the green slopes are not fixed, they just sit.

 

Some engineering work was done on some of the green slopes if you look at the top pictures.  I have 4 Emerald nights so I feel that this was OK.

Anyway, Emmet is very proud of the 2 additions to the engine shed , which now contains some 14 engines (I think) some are lego originals and some are MOCs - with many coaches and trucks.

Great looking builds! Keep up the awesome work!

Great locomotives!!!  Nice bogies system!

These look really quite good, even if the boilers are a little large in diameter. How well do they perform, especially the 4MT? I've never had much luck with steam engine drivetrains, does the L-motor help in that regard?

Beautiful MOCs!

The short model is really nice but the long one is the best in my opinion!

I know the boilers are a little large in both cases, but I like this design that comes from the Emerald night.  Both engines perform well, the 9F is geared the same as the EN and the 4T is geared down 3 times as it is a "branch line" engine.  The 9F runs better than I expected but it took a lot of work to get it to that stage, and my aim was working model that was reasonably robust rather then some of the amazing creations you see on this site.  The 4T was finished recently and it only took 3 rebuilds to get it work well.  Both need a little work on detail I know, but I don't get much time.  Thanks for the interest

Note : the emerald night has a design flaw with the valve gear that needs correcting before it runs smoothly, these engines use the same modification design.
