The Sava Railways Ten Wheeler 4-6-0 steam engine #982 "Lady", utilizing the fantastic new medium drivers from Big Ben Bricks.
About this creation
This is my Sava Railways #982 "Lady", a Ten Wheeler class 4-6-0 steam engine based off of the Grapevine Railroad's "Puffy" near Dallas, Texas. The real Puffy is an almost Sand Blue colored locomotive, but LEGO has not made a large enough variety of parts to be able to build this design in that color, and since I wanted to build the BM&R #425, a blue engine, I decided to go with a entirely different color, one I had not yet used for a steam engine.
If you look at her design, you'll notice there are a lot of similarities between Lady and my American 4-4-0. Both of the designs use the micro train wheels for the pilot truck as well as nearly identical pistons. What's signifigant about the pistons is that unlike my other designs, the actual piston does not move, rather, the push rod slides up and down the piston using a minifig box-wrench. Unfortunately, while this does allow for a truely round piston housing, the handles of the box-wrenches make the effective width of this "6-wide" steam engine to be nearly 9 studs!
I wanted to incorporate some brick built detail into the tender, instead of relying on purely stickers. In order to do so, I had to wrestle in some interesting SNOT techniques to create the effect I desired. However, I was still able to keep enough free space inside the tender so that I could swap out the wheels for a 9v train motor.
Here you can see how Lady negotiates the tight radius of LEGO's track geometry. Like my 4-4-0, Lady's pilot or pony truck floats beneath her, allowing her boiler to slide back and forth on top as she makes her way along the track. However, because her pilot truck is so much closer to her drivers than my 4-4-0, Lady is much more stable at higher speeds, which makes her a more reliable performer.
The comment I receive most often regarding Lady is on the detail of her smokestack or funnel. The design itself is pretty straight forward, but sometimes it's hard to make out. It's nothing more than a black palm tree trunk segment with a yellow radar dish and a micro train wheel on top, with custom length of black flex tubing stuck down the center to keep everything together. The American and Texas flags are custom stickers, which I designed specifically for use on this locomotive (though I will most likely be adding them to a few others.
As I've said in the past, cab interiors are my weakest point. But, as always, I've tried to incorporate a few standard elements into the cab, including dials, levers, firebox door, and drivers's seat.
