Gresley conjugated Walschaerts valve gear + suspension

[Aerolight]

I'm back baby 

Tried to get every angle but sure I missed some.

Sry no pics of the baker valve gear it hit hard when I realized it would be to large so it got tossed asunder in favour of this.

Wheels are custom but somewhere between xl and xxl i think - no binding on curves at all 

The limiter is not quite limiting enough so reverse is no so smooth easy fix but eFfOrT

The 9f is done but digital only - the mechanism is one I purposed to get the 9f to beat the t1 (and mallard) if the yanks manage it; but seeing I lack 10 million pounds a model will have to do. How and why the 9f you ask find out in 6-8 months when I finally get around to ordering the many parts (60ish cm long)

The running little 1/360 stud train set in a carriage is finished as has been for months but have been waiting as its probably my best Moc, people how have seen it think so at least (especially considering it has no modified pieces)

Forgive the odd driven (not here) tender it's just for a basic train that can pull the small train carriage with no traction tires as the set is driven by the bogies.

Awesome to see it move so smoothly.

Thanks it was a pain with my 3d printer as the holes need to be smaller than Lego standard to reduce play enough for the middle cylinder to move the same-ish distance as the outer 2

Realy smooth looking in action

Very cool looking running gear!

[LEGO Train 12 Volts]

Gorgeous!

Seeing such a small locomotive in action but with such full detail on the operating valves is amazing!

Another peculiarity is the movement: as already mentioned, is extremely smooth and without jerks!

Woooow! A small locomotive with such a complete mechanism...I watched the video several times, since it clearly shows all the parts and their movement! Really interesting! 

The use of a differential for actuating the reverser is a fantastic idea!

Ciao!

I agree that this model shows some incredible features. That you were able to integrate the reverser with it's clever actuation method, all the valve gearing parts and a full suspension is amazing. Great job!
