The fastest steam locomotive in the world


Recommended Posts

Here is my first build for this GB.   It is LNER A4 No 4468 Mallard.   On 3 July 1938, this engine set a world speed record for steam locomotives of 126 mph.  This record still stands.  Wikipedia has a very informative article on the loco and the record setting run.

 

https://en.wikipedia.org/wiki/LNER_Class_A4_4468_Mallard

 

There are white metal kits of the Gresley A4 available but I'm not going to use one.   I have numerous A4 components in the spares box which I will chuck together to produce a static display model.   I intend to represent Mallard as it looked during the speed run. 

 

The first component is a Hornby bodyshell.  This is of Mallard in British Railway colours and so will need some modification.  The good thing is that it already has the double chimney.  The first batch of A4s were built with single chimneys which caused the exhaust to hug the top of the casing, obscurng the view from the cab.   The commemorative plaques were fitted in 1948 and so will need to be removed.  The valances covering the valve gear and cylinders  were removed durng the second world war to ease maintenance.  These will have to be added.

Components for the chassis.  The driving wheels are from a Gresley A3 but were identical to the A4 wheels.  I believe the chassis block is also from an A3.

Components for the tender.  I believe the tender body and chassis components were from two different releases of the Hornby A3.  The wheels are from a Hornby Mallard.

Most of the previous components (with the exception of the two keeper plates) are taken from the spares box.   The items shown below (coupling rods, connecting rods, cylinders and drain cocks) were bought especially for this build.

The tender will need a fair bit of work.  Mallard did use corridor tenders but not on the day in question.  The corridor connector will need to be removed and the rear bulkhead and decking replaced.

I've considered making this a multi-sensory model by sticking a piece of aniseed in the bodyshell so it smells like Mallard after the speed run.  :lol:  The Wikipedia article will explain why.

Fascinating subject choice boss and it seems you've planned this one well in advance :speak_cool:

Now, sound and lighting added to a model is one thing, even the 'real steam' on some trainset set-ups, but adding authentic smell is taking things to new levels!

Please stand back from the platform edge, a nerd is approaching! Stable mate Sir Nigel Gresley holds the post-war world steam record so it's a 1/2 for the big beasts! tbh don't understand all the hype about Flying Scotsman apart from a sociological perspective, but that's way off-topic.

It's a shame the engines got sheered off the roof by that low gantry 2 seconds after the picture was taken :whistle:

And yet my imagination actually likes the idea. Smell is so evocative. I think of the creosote used on the ties for the railroad running behind my grandfather's cottage. Can still almost smell it 34 years later.

126 mph, I believe!

You are quite right.  A typo on my part, I'm afraid.   I have amended the original post.

 

106 mph was quite old hat in the 1930s.  The GWR's City Of Truro first exceeded 100mph in 1904!

Let's not start that argument here otherwise we might have to mention the loco that @Mjwomack said that he

The.story of City of truros record is fascinating, simply put it seems a correspondent of the railway magazine no less logged it, bit great Western weren't sure they wanted a reputation for being speed freaks. How times changed

The first job is to wrk on the body shell.   I removed all the seperately fitted parts:  boiler handrails, buffers, safety valves, nameplates, whistle, glazing and cab interior.  I then started work to remove the commemorative plaques and the shedplates which are moulded on.

The chassis was not designed to fit on this bodyshell, so I widened the groove at the back to allow the tab to fit in it.  At the front there is no structure to connect to the chassis so I provided one.  It was easy.   It's just a big chunk of Milliput.  :lol:

While I'm working on the bodyshell, I decided to paint up the wheels.  The idea is to spray them silver from a rattle can and then paint the centres with a hairy stick.  I managed to disassemble the axles for the bogie and Bissell truck.  As I couldn't get the driving wheels off the axles, I cut slots in a piece of cardboard.  But then I realised I had to remove the wheels.  The wheelset and the chassis were not designed to go together so the bearings on the axles do not fit into the slots on the chassis.  Eventually I managed to remove the wheels using a fair bit more brute force and ignorance.  :)

Mallard really needs some carriages.  I have some really reeeeely old Hornby Railroad Gresley teak coaches with a dreadful attempt at a teak finish.

So I thought it might be nice to repaint them in something more like a teak finish.  The first setp was to disassemble the coaches.   The bogies simply pull off.  The body has to be unclipped at both ends.

The transparency assembly can then be unclipped in the middle.  The interior then falls out, as does a ballast weight.  The body ends simply slide out.

I've always really disliked the white interior of these coaches.  A simple repaint of this part will do wonders by itself for these coaches.  I was pleased to see that Hornby have actually provided different seating for the First class compartments.

Bissell truck

The old issue of the rear pony/Bissell truck - the LNER A4 Pacifics did not have a rear "pony truck" as used in most models. The rear carrying wheels were in Cartazzi axleboxes which were part of the frame but allows some sideways movement. The new Hornby A4 has the correct set up.

How Hornby still seem to sell these at £29.49 when pre-owned ones go for as little as £10 is a mystery.

Cartazzi!   That's the word.  I thought Bissell was incorrect as I typed it.  The model does have a Bissell truck, but the pivot arm will probably be hidden behind the valances.

 

The RTR Hornby A4 that I have is from 2005.  The rear wheels are fixed but they don't have any flanges.

I added the valances using 20 thou plastic card.

I reinforced the joint on the inside by packing it with bicarbonate of soda and dripping superglue on it.  It's not very tidy on the inside, but it is nice and robust.

Moving back to the carriage, I painted the interior.  Even this minor thing makes a huge improvement.

I used a magic eraser to remove the lettering on the exterior of the carriage.  I masked the sides and sprayed the roof to get rid of the plasticy sheen.  I used Lifecolor UA-563, which is Gray 36622.  I then lightly sprayed random patches of a slightly darker grey. In this case Lifecolor UA-036.

He really knows his stuff! Some very good commentary on the equally excellent photos

 

Now I want to build a Sentinel railcar!

I take it you mean this one😆

 

Egypt Railways - Egyptian State Railways Sentinel railcar (1951)

 

not my picture.

 

Not in the time period for this GB as built in 1951 - some spent their working life in Egypt  and one if preserved at the Buckinghamshire Railway Centre
