| This is my first Lego live steamer built using studless bricks and BBB wheels. |
| Side view of the front half. The BBB wheels are clearly visible. |
| A small locomotive for a small layout... |
| A 16-tooth gear was press fit onto the steam engine's shaft. |
| The articulation: two pivot points sandwich a U-joint used to carry power from the front haft to the rear one. |
| After a few laps, the wheels have lost their shine. |
| The live steam bits on the left, the Lego chassis on the right. |
| The large gear (40-tooth) at the front send power to a 12-tooth gear near the center of the engine. From there a second shaft, driven by a 20-tooth gear sends power to all the wheels via three U-joints (One for articulation and one per half-chassis for leveling). |
| This is the rear half chassis which carries the boiler, burner and fuel tank. |
| Bottom view of the front half of the chassis. |
| Rear half, bottom view. |
| This view shows that the chassis can accomodate a much tighter radius than my layout's R1 curve (60cm / ~2ft). |
| In this view, the chassis is up side down and the articulation of the axles is shown. |
| See the beast in action! (3MB) |
