This is just 1 of many locomotives I am currently working on the (LMS) Coronation Class the 'Duchess of Sutherland'.

Wanted to have 3 headlamps. So I decided to go for the 2nd time it was used as a royal train when it hauled Prince Charles on the 22 March 2005 from Settle to Carlisle.

Model has working smoke/draincocks using a 2 vapouriser to generate 'steam/smoke. Tender is currently being improved. Just requires battery and something to control it. Torn between using a PFX brick or Hornby's new decoder which can be controlled via a phone. PFX I am familar with but sound is not great(I am no sound engineer). Hornby's solution I have yet to figure how to integrate chuffs with their superb sound (although I do know how to convert it to battery).

I appreciate this is not for the purist but their is a lot of complex techniques in the build that maybe of intrest to those who are. All 3d parts/stickers I have designed and made. 

This project has been on and off for many years.

 

Video testing the smoke/draincocks. Plus completed electrics in loco with 2 vapourisers/speaker/3 lamps. Also of intrest is LEGO bending for tapered firebox.

Nice work! I can't think of anything other to say besides this is a fantastic MOC!

Wow.

That's an amazing looking engine right there.

Hi Liam,

really looks fantastic!

Is it meant to ride on track or ist meant only as static display?

if it rides on track, which radii does it handle?

That's a magnificent piece of engineering!

Can you tell us where you bought the vapourisers? And what parts did you use for the chimney and the buffers?

Marvellous design! Neat ideas with the usage of parts and stickers 

Thank you Murdoch17 , ivanlan9 , SD100 and  Darkkostas25

CaL it will move. Smallest track radius will be R88. The driving wheels are 3XL and have been succesfully tested on R40.

 

Thanks Sven J. The buffers/chimney where designed and 3d printed by myself.

The best vapouriser have a capacitor plus a larger chip next to them (see picture). Vapourisers with the smaller chip(normally without capacitor) have a considerable delay when switching. Unfortunately they are now the most common.

Thank you!

On first look, I wasn't sure if your locomotive was LEGO. Great work on it. Plenty of details, but in a way that makes it more realistic than most MOCs. Keep up the good work.
